Chemical Change Definition in Chemistry

Chemical Change Definition in Chemistry A chemical change, also known as a chemical reaction, is a process where one or more substances are altered into one or more new and different substances. In other words, a chemical change is a chemical reaction involving the rearrangement of atoms. While a physical change can often be reversed, a chemically change typically cannot be, except through more chemical reactions. When a chemical change occurs, there is also a change in the energy of the system. A chemical change that gives off heat is called an exothermic reaction. One that absorbs heat is called an endothermic reaction. Key Takeaways: Chemical Change A chemical change occurs when one substance is transformed into one or more new products via a chemical reaction.In a chemical change, the number and type of atoms remains constant, but their arrangement is altered.Most chemical changes are not reversible, except via another chemical reaction. Examples of Chemical Changes Any chemical reaction is an example of a chemical change. Examples include: Combining baking soda and vinegar (which bubbles off carbon dioxide gas)Combining any acid with any baseCooking an eggBurning a candleRusting ironAdding heat to hydrogen and oxygen (produces water)Digesting foodPouring peroxide on a wound In comparison, any change that does not form new products is a physical change rather than a chemical change. Examples include breaking a glass, cracking open an egg, and mixing sand and water. How to Recognize a Chemical Change Chemical changes may be identified by: Temperature Change - Because there is an energy change in a chemical reaction, there is often a measurable temperature change.Light - Some chemical reactions produce light.Bubbles - Some chemical changes produce gases, which can be seen as bubbles in a liquid solution.Precipitate Formation - Some chemical reactions produce solid particles that may remain suspended in a solution or fall out as a precipitate.Color Change - A color change is a good indicator that a chemical reaction has occurred. Reactions involving transition metals are particularly likely to produce colors.Odor Change - A reaction may release a volatile chemical that produces a characteristic scent.Irreversible - Chemical changes are often difficult or impossible to reverse.Change in Composition - When combustion occurs, for example, ash may be produced. When food rots, its appearance visible changes. Note a chemical change may occur without any of these indicators being observed. For example, the rusting of iron produces heat and a color change, but it takes a long time for the change to be evident, even though the process is ongoing. Types of Chemical Changes Chemists recognize three categories of chemical changes: inorganic chemical changes, organic chemical changes, and biochemical change. Inorganic chemical changes are chemical reactions that dont generally involve the element carbon. Examples of inorganic changes including mixing acids and bases, oxidation (including combustion), and redox reactions. Organic chemical changes are those the involve organic compounds (containing carbon and hydrogen). Examples include crude oil cracking, polymerization, methylation, and halogenation. Biochemical changes are organic chemical changes that occur in living organisms. These reactions are controlled by enzymes and hormones. Examples of biochemical changes include fermentation, the Krebs cycle, nitrogen fixation, photosynthesis, and digestion.

Whats the Average College GPA By Major

What's the Average College GPA By Major SAT / ACT Prep Online Guides and Tips If you’re still in high school, you might be curious about how college GPAs work and what you can expect for grades given your major of choice. Just like high schools, colleges vary in how they calculate GPA. Grade inflation also significantly affects college GPA at most schools, causing many students to end up with higher GPAs in college than they had in high school. In this article, I’ll give you the facts about average GPAs at different types of colleges and within a variety of college majors. What's the Average College GPA? The average GPA for students at four-year colleges in the US is around 3.15, or a B average. This is much higher than it’s been in the past, a trend that demonstrates that grade inflation is a very real phenomenon for colleges. For example, a C used to be the standard average grade, but now a B is considered average. Why is this? One factor might be that professors are more vulnerable to student critiques in online forums and are sometimes forced to answer to angry parents if they give poor grades. The job of a professor can partially depend on how pleased his or her students are with the class, which is inevitably tied to what grades students get. As college becomes more and more expensive, both students and parents expect high grades so they can feel as though they're getting their money's worth. This is also a likely reason for grade inflation, especially considering the disparity in average GPA between public and private colleges: according to GradeInflation.com, public schools have around a 3.1 average GPA, whereas private schools have around a 3.3 average GPA. Grade inflation might also be happening because professors don’t want to jeopardize students' future chances at grad school or job opportunities by doling out low grades in an academic environment that has now come to expect Bs as the norm. However, telling you the overall average GPA across colleges and majors is somewhat meaningless as a statistic since GPAs vary so drastically by school and by major. Many schools give students two different GPAs: a cumulative GPA that takes into account all their classes, and a major GPA that only includes classes that count toward their major. In the next few sections I’ll get more specific about the average GPAs you can expect for different major fields and types of schools. GPAs by Major Science majors tend to have lower GPAs on average, with chemistry being the major with the lowest average GPA. Meanwhile, education majors earn the highest GPAs on average. Why this disparity? Grade inflation is more rampant in non-STEM fields because assignments are usually more open to interpretation, and there aren’t always clearly defined right or wrong answers. Professors tend to give students the benefit of the doubt due to the factors I mentioned previously (i.e., the impact of student evaluations, the expectations of high grades by students and parents, and professors being "too nice"). If a student gets a problem wrong or follows incorrect procedure in gathering data, it’s clear that he or she will earn a lower grade. If the student doesn’t write a clear enough thesis for an English paper, on the other hand, it’s a more subjective situation. The majors I’ve listed here come from a 2010 report by Dr. Kevin Rask of Wake Forest University. It’s difficult to say what the average GPA for one major is when you’re looking across a bunch of different schools. Each program is different, so the average GPA for these same majors at your college might be much higher or lower than indicated in the table. Major Average GPA Education 3.36 Foreign Language 3.34 English 3.33 Music 3.30 Religion 3.22 Arts 3.19 History 3.19 Computer Science 3.13 Political Science 3.11 Physics 3.10 Geography 3.09 Philosophy 3.08 Geology 3.03 Biology 3.02 Psychology 2.98 Economics 2.95 Math 2.90 Chemistry 2.78 Bonus: Curious about what the easiest college majors are? Read more here! Chemistry is a tough subject (except when it's between u and me, baby). GPAs by School Below, I've listed 10 schools for each category of selectivity (highly selective, selective, and less selective) and their average GPAs so you can get a sense of the distribution of college GPA. Here's what I mean by these levels of selectivity: Highly selective schools are schools that have a less than 15% acceptance rate Selective schools are schools that have a 20-50% acceptance rate Less selective schools are schools that have an acceptance rate higher than 50% You’ll notice that the most selective colleges have higher average undergraduate GPAs. This could be because they are more vulnerable to the factors I listed earlier that contribute to grade inflation. Moreover, because these colleges are admitting increasingly higher-achieving students, it’s more difficult to set standards in classes that are high enough to prevent most people from earning As. I consulted GradeInflation.com to find these GPAs. The years next to the GPAs indicate the most recent GPA data available from the school. All schools are arranged alphabetically. Highly Selective Colleges College Acceptance Rate Average GPA Brown University 9.3% 3.63 (2012) Columbia University 6.1% 3.45 (2010) Cornell University 12.7% 3.36 (2006) Dartmouth College 10.4% 3.46 (2014) Duke University 10.8% 3.51 (2014) Harvard University 5.2% 3.65 (2015) MIT 7.2% 3.39 (2015) Princeton University 6.4% 3.39 (2014) Stanford University 4.8% 3.57 (2011) University of Pennsylvania 9.3% 3.44 (2015) Selective Colleges College Acceptance Rate Average GPA Bates College 21.9% 3.36 (2006) Boston University 25.1% 3.16 (2014) Carleton College 21.2% 3.42 (2004) Emory University 22.0% 3.38 (2012) Grinnell College 28.9% 3.34 (2007) Kenyon College 33.8% 3.42 (2015) Lehigh University 25.2% 3.17 (2012) Spelman College 40.1% 3.16 (2013) UC San Diego 34.2% 3.14 (2015) Vassar College 23.8% 3.58 (2015) Less Selective Colleges College Acceptance Rate Average GPA Butler University 65.1% 3.25 (2007) Drury University 72.4% 3.30 (2013) Furman University 61.2% 3.20 (2014) Hope College 84.0% 3.39 (2009) James Madison University 75.2% 3.15 (2013) Portland State University 92.0% 3.14 (2011) Rutgers University 57.8% 3.09 (2013) University of Alabama 53.3% 3.13 (2015) University of Northern Iowa 80.8% 3.02 (2014) University of Utah 66.2% 3.10 (2013) Want to build the best possible college application?

Average college GPAs won't mean much for you if you're still in high school, but it's good to know how GPA works in college because it can impact your future career. If you end up going through a job recruiting process toward the end of college, your GPA will likely be one of the factors that is strongly considered by recruiters. As I've said, however, GPA varies quite a bit across different schools and majors. Recruiters will be looking at how your GPA compares with that of other students at your school who are in the same field. Overall, your experiences with projects and other jobs will carry more weight than will your GPA in most hiring decisions. It's safe to say that if your college GPA ends up being at least a 3.0, most employers won't be concerned with it. Another matter to take into consideration is grad school. You'll have to be a little more serious about keeping your GPA up in college if you plan to go to grad school (especially if you have your sights set on law school or medical school). Grad programs want dedicated students who are passionate about the field of study they've chosen. A high college GPA in relation to your peers in the same field will demonstrate that you were able to consistently exceed expectations. If grad school might be on the horizon for you, don't slack off during your freshman year of college! You should make sure your GPA is solid from the beginning so you don't mess up your plans later on (but also try and have fun sometimes because college is awesome). Let's face it, we all kind of want to be lawyers just so that we can be as cool as Saul Goodman (aka James McGill ... you should really watch Better Call Saul) Conclusion: What's the Average College GPA? Figuring out the average college GPA is not as straightforward as you might assume it is. Because students take such different classes at a wide variety of institutions, it’s difficult to compare one GPA directly with another if both students aren’t attending the same college and taking similar classes. Overall, college GPAs have risen in recent years due to grade inflation caused by a variety of factors, including the easier accessibility of professor reviews, parents' expectations of students' grades, and grad school competition. Don’t choose a major or a college because you think you’re going to be able to get a higher GPA in that program. If you work hard in a field you truly enjoy, the good grades will most likely follow!

The Sky Is the Limit Essay Example | Topics and Well Written Essays - 500 words

The Sky Is the Limit - Essay Example The main challenge I encountered when writing my essays is related to sentence construction. This was problematic especially in my in-class essays since I had to write these within a certain time frame. I often mixed verbs when writing and this negatively impacted on the grades which I obtained. However, my out of class essays have been much better since I took my time to try to construct meaningful sentences. My first out of class essay was not that good but the second one was much better. I wrote about the topic related to internet censorship in the second out of class essay and I scored a better mark compared to the previous assignment. This comes with effort and perseverance and I am glad that I am improving on a daily basis since I always learn something new through practising to write. The other important thing I have realized is that writing skills can be improved when one is aware of what he or she is writing. The topic must be clear and it is important to carry out some research to gather as much information as possible before writing the actual essay. This helps you to remain focused while at the same time avoiding irrelevant material that might not interest the reader. Essentially, a good essay must be well thought and it should show direction where a reader can be in a position to follow what the writer is trying to say. The other important I have discovered when writing an essay is that one should first draft it to come up with a sketch of the final draft. This helps the writer to revise the work so that he can be able to edit the mistakes. It is also important to read the essay aloud so as to be able to see any grammatical mistake.  Ã‚  

Law - Civil Procedure (Hong Kong) Essay Example | Topics and Well Written Essays - 1500 words

Law - Civil Procedure (Hong Kong) - Essay Example James (1854) 5 De G.M. & G. 876 and its brethren (Novello v. James (1854) 5 De G.M. & G. 876). This undertaking is not given to the party against whom the injunction is sought, but to the court who is overseeing the proceedings from which the injunction came (Zuckerman, 1994, p. 546). The reason that the plaintiff has to give this undertaking is in the event that either the injunction is dismissed for any reason, or that the defendant wins in a trial on the merits. In either of those cases, it must be shown that the defendant was kept from exercising his or her lawful rights, and was harmed by this. Therefore, the money given as an undertaking must be equivalent to what monetary damage that the defendant would experience because of this loss of rights. This undertaking is a safeguard for defendant’s rights, as the court is sworn to give both parties equal treatment, and it is a matter of â€Å"elementary fairness† that this undertaking is given (Kirklees Borough Council v. Wickes Building Supplies Ltd. [1991] 3 W.L.R. 985). However, the entitlement to damages is not independent of the undertaking (Fletcher Sutcliffe Wild Ltd. v. Burch [1982] F.S.R. 64), and whether or not the defendant is entitled to the undertaking is not decided by the material event, such as the injunction being dismissed or the defendant prevailing on the merits, but, rather, is a discretion of the court (Attorney General v. Albany Hotel Co. [1986] 2 Ch. 696). This discretion is not limited in any way (Cheltenham and Gloucester Building Society v. Ricketts [1993] 1 W.L.R. 1545. This means that the court does not necessarily have to grant the defendant the damages that have been deposited, even if the defendant prevails on the merits and even if the injunction is dismissed, and this discretion about whether or not to award the defendant is essentially unbridled. This brings up the question of what the undertaking is meant to compensate. The injunction usurps the defendantâ€⠄¢s rights in some way, and this is a harm that is suffered by the defendant. For instance, perhaps the defendant is enjoined from keeping open his business after he has already opened it, because the plaintiff seeks an injunction based upon the fact that defendant is, say, operating a business that is not zoned for a particular area. As it turns out, the zoning for the area is proper, and the existence of the business in this area is also proper. Yet Defendant has now lost several days or even weeks of business. This is a clear harm to the defendant, yet the court does not have to award the defendant the undertaking if the court deems this to be fit, and this discretion is not limited, therefore the defendant probably could not prevail on an appeal on the matter, as appeals courts are loathe to interfere with judicial discretion. This is obviously an injustice, but, since an undertaking is not a function of tort, criminal or contract law, it is difficult to classify it, so it is di fficult to state what is proper when examining judicial discretion on the issue. One clear way that the defendant may get the undertaking would be when it is clear that the injunction should never have been granted (Norwest Holst Civil Engineering Ltd. v. Polysius [1987] CA Transcript 644. However, there is a difficulty in ascertaining when an injunction should

Religious and Ethnic Groups Essay Example for Free

Religious and Ethnic Groups Essay Religious And Ethnic Groups The religious and ethnic groups that I have chosen to write about are Jehovahs Witnesses and Pacific Islanders. The reason I have decided on theses two choices is because I feel that out of my choices to write about these two I know the least about, and I wanted to know more. I always have been interested in different religions since I do not have one myself, but never found the time to pursue research into very many of them. I have never really thought about researching other ethnic groups, but I feel it is a good idea to do as much research as possible to connect as well as I can with my patients. I will be touching on the same subjects with both choices and show what I learned through this journey. My selected religious group of Jehovahs Witnesses differs from other religious groups because they refuse military service and blood transfusions, refuse to salute the national flag, do not believe in abortion, do not observe traditional holidays like Easter, Christmas, or their birthdays, and go door-to-door preaching and handing out literature (Engardio, Shepard, n.d.). Jehovahs Witnesses do not usually associate with people outside of their religion, and you can not be a member unless you have been baptized. Jehovahs Witnesses believe that Jehovah is the creator of all things and is the only true God, while also believing that the Holy Spirit is an active force and not a person (Watchtower online library, n.d). They also believe that paradise is here on Earth and they do not believe in Hell (Bourque, 2012, Ten things you didnt know about Jehovahs Witnesses). The experience with Jehovahs witnesses with others that do not share its beliefs or practices has not always been a positive one. When they go door to door they often are greeted with rejection because they consider secular society to be morally corrupt and under the influence of Satan (Wikipedia, Jehovahs Witnesses, para.3). It is also very difficult to have a relationship of any kind to get to know them because of their lack of association with others  outside of their own religion. The ways that Jehovahs Witnesses have contributed to American culture are by winning 50 out of 62 supreme court battles, and set many precedents regarding many religious freedom issues (Engardio, Shepard, n.d.), they have a way of convincing criminals and immoral people to change how they live, they are also usually one of the first responders on a scene of a natural disaster to help people, like in the Boston Marathon bombing. They were also guinea pigs for having bloodless surgery which is now widely available to anyone (Engardio, n.d.). Some examples of discrimination or prejudice that the Jehovahs witnesses have endured are; raids on their houses of worship, unlawful detention, denial of employment and education, and confiscation of their property (Engardio, n.d.). On August30, 2012 Naplenews.com posted a story of two teachers suing a school district for discrimination by declining to re-hire them after finding out they were Jehovahs Witnesses (Bhasin, 2012). Posted on annarbor.c om December13, 2011 a nursing home illegally fired an employee for requesting certain days off during the week because of her religion, which happened to be Jehovahs Witness (Higgins, 2011). On both of these sources the employer was the source of discrimination and court cases came about because of the discrimination. During my research on Jehovahs Witnesses I learned more than I expected to learn. I now have an understanding on why they do not salute the flag, do not donate blood, and do not socialize much outside of their own religion. I also learned that they do believe in divorce and dancing, which most people believe they do not do. I believe everyone believes in their own personal beliefs. Understanding why they do, or do not do things is important to know so that way I can make educated judgments, and better support a variety of people. The Ethnic group I chose is Pacific Islander to get more familiar with their ways and traditions. They differ from other ethnic/racial groups because they often live a laid back style counting on one another as they are all extended family that works together for the better of their community. Pacific Islanders did not have a form of written language for centuries using music to as a way of expression. They would play wood drums made of hollowed logs, play small and large gourds, play split bamboo, and use their voices as a way of express ion. They also have traditional weddings where it is a whole family event, and the family pays for it. When there is  a funeral everyone wears black and extended family prepares food for up to five days (Swain, n.d.). The experience of Pacific Islanders with other groups have been positive. Pacific Islanders in general get along well with others and are very family oriented, which draws people to them. Pacific Islanders have contributed to American culture in many ways. They have been leaders in every aspect in government, business, science, medicine, the arts, education, and the armed forces (Washington, 2013. par.3.). Many Pacific Islanders have also been awarded the medal of honor. A specific example of discrimination against Pacific Islanders is in 1974 a suit was filed against Alaskas Wards Cove Company. The all white management segregated them from everything. They made them work in racially segregated jobs and were segregated when it came to housing and eating. When it came to the signing in 1991 of the federal Civil Rights Act this suit was still pending and excluded these specific people and allows Alaskas Wards Cove to operate above the law, and continues its discriminatory practices (Lee, 1992, par. 3.). Once again the source of this discrimination is the employer, which happens to have an all white management team. What I did find on Pacific Islanders has helped me understand a little bit more about them. Pacific Islander can mean different things to different people, and it is important not too generalize the race. I now also understand that it is their culture to have strong relationships with their families and their community. It was interesting to find out that music has played a big part of their culture when they had no written language. I enjoyed doing this research and finding the reasons behind why these groups believe in what they believe in. The biggest discrimination similarity that I found between these two groups that I researched was mostly employer discrimination. The biggest differences that I found between the two are they are of different races and believe differently in religion. If I could draw any conclusions from these comparisons I would say that employer discrimination seems to be predominant, even to this day. I feel that in doing this research that no one is exempt from discrimination, and we all have to stand up for what is right and for what we believe in, while still respecting others beliefs.

Globalisation - Australia and Asia Essay examples -- essays research p

Edward Said states, â€Å"No one today is purely one thing. Labels like Indian, or woman, or Muslim, or American are no more than starting points.† Said’s idea illustrates the evolution of relations between communities as a result of globalization, and the understanding and recognition of other cultures through the interpretation of cultural borders. In this essay I will analyse to what extent globalisation is affecting identity formation, and also the roles of cultural borders in today’s world. I will assess whether through globalisation of the media we are in fact overcoming cultural borders and traditional stereotypes and in turn forging a mutual respect between foreign communities, or as Said argues (Said cited in Crary & Mariani1990), whether globalisation and Western media dominance through peripheral and Third World societies is perpetuating Western superiority, â€Å"the ever rolling march of commodification, the old form of globalisation, fully in keeping with the west, which is simply able to absorb everybody else within its drive† (Hall 1991), and spreading hegemony, with little or selected representation of local culture. I will be using studies of Australia/Asian relations to illustrate these ideas. In order to apply these ideas to Australian and Asian relations, we must first establish how we some have come to realise that â€Å"no one today is purely one thing†, as opposed to years gone by. As Said (1978) and others have shown, Europe, from which Australia’s culture originates, has traditionally viewed Asia and Asians with contempt and inferiority, and â€Å"one of its deepest and most reoccurring images of Other† (Said 1978, p.1). Asians have been â€Å"repeatedly characterised by some western texts as alternatively lazy, stupid, mindless, barbaric and untrustworthy [which has] served as a guarantee of the ‘superiority of the Briton, American, German or Australian over many years† (Birch, Schirato & Srivastava 2001, p.5). As Said (1978, cited in Crary & Mariani1990) and Birch et al. (2001) show, Asians have been represented as inferior and essentially different to their colonising European counterparts. Australians, too, have looked (and argu ably continue look) upon Asian people (and in light of this essay any other people) as essentially different to themselves.

How to Maintain Biodiversity

There are several important ways in which humans can slow biodiversity loss, although there is no way to bring back the species that have already gone extinct. Protecting Areas Creating protected areas where human activity is limited is the best way to prevent deforestation and exploitation of organisms and the resources they need to survive. In order to truly make a difference, much planning needs to go into the creation of a protected area. It needs to consider all elements of the ecosystem it is trying to protect, so that it isn’t too small.It needs to include all resources that are utilized by its inhabitants; for example, leaving out a stream where half of the mammals go to drink would not make a protected area very effective. Preventing Species Introductions It is often much easier and less expensive to prevent a problem from developing in the first place than to try to fix it once it occurs. This is the case with invasive species, which can wreak havoc when introduced t o ecosystems that aren’t prepared to deal with them.Many governments prohibit bringing foreign plants and animals into their countries without authorization; some even go so far as to disinfect landing planes and the shoe-bottoms of people on them. Informing / Educating Education is a powerful tool, and the more people know about biodiversity loss, the more they will be prepared to help slow it. Spreading the word about detrimental human effects on plants and animals can encourage people to change their ways and effect changes to preserve biodiversity.Slowing Climate Change Climate change is the documented cause of several extinctions that we know about, and has likely caused hundreds of species to go extinct about which we may never know. Any efforts as individuals, organizations, or governments, to slow current human-caused global warming is a step towards slowing biodiversity loss. Promoting Sustainability Sustainable agriculture is much better for the environment than gra zing and cropping that rely on clearing swathes of forest or field.

Dna Dna and Alternate Dna Structure Essay

Dna Dna and Alternate Dna Structure Essay Dna: Dna and Alternate Dna Structure Essay DNA BY Navdeep Singh Period 4 Date 5-18-2015 Mr.Sanchez Chemistry B Inside the human body there lies something very unique to us that we call the DNA. It is predicted that there are over 3 billion base-pairs of DNA inside the average human. DNA itself is huge so let’s cover the basics you need to know about it. The DNA includes, RNA, Double-Helix, Base-pairing and an alternate DNA structure. It may seem amazing but beware your DNA can be damaged and or Replicated. In crime DNA comes very handy because detectives use forensics. Every living thing on the planet or most things have a DNA inside of them, therefore DNA is said to have evolved over the trillions of years. Translation is the final step on the way from DNA to protein. It is the synthesis of proteins directed by mRNA template. The information contained in the nucleotide sequence of the mRNA is read as three letter words (triplets), called codons. Each word stands for one amino acid. During translation amino acids are linked together to form a polypeptide chain which will later be folded into a protein. The translation is dependent on many components, of which two are extra important. First of all; the ribosome which is the cellular factory responsible for the protein synthesis. It consists of two different subunits, one small and one large and is built up from rRNA and proteins. Inside the ribosome the amino acids are linked together into a chain through multiple biochemical reactions. The second component is the tRNA, a specialized RNA molecule that carries an amino acid at one end and has a triplet of nucleotides, an anticodon, at the other end. The anticodon of a tRNA molecule can bas e pair, i.e form chemical bonds, with the mRNA's three letter codon. Thus the tRNA acts as the translator between mRNA and protein by bringing the specific amino acid coded for by the mRNA codon. Transcription sequences are found close to the ends of the sequences that are not coded. There are two types of bacteria. In the rhoindependent terminators, inverted repeat sequences are transcribed, they can then fold back on themselves in the hairpin loops, causing RNA pol to pause and resulting In release of the transcription. On the other hand, rhoindependent terminators make us use of a factor called rho, which actively unwinds the DNA-RNA hybrid formed during transcription, therefore releasing the newly and improved synthesized RNA. In eukaryotes, terminations of transcription occurs by many and a various different processes depending on the exact amount of polymerase that have or has been used. Now For the Pol 1 genes, In it Translation is stopped by using a terminal factor, through a mechanism that is very similar to rhoindependent termination sequence that includes a polykaryotic termination. Transcription of the poll III genes that end after transcribing a termination sequence that includes a polyuracil stretch, by a mechanism resembling rho-independent prokaryotic termination. The Termination of the Pol II transcripts, however, is far more complex and very complicated. The DNA has a strand which is called the Double-helix. Hybridization is the process of complementary base pairs binding which in time forms a Double-Helix. Melting is the process by which the interactions between the strands of the Double-Helix are broken, separating two nucleic acid strands. These bonds are very weak, and can easily be broken very fast. They are also easily separated by gentle heating, enzymes, or the brute force of physical force. The melting occurs sometimes at a certain point that is in the nucleic acid. T and A are the richer

The Asian Longhorned Beetle Prevention and Control

The Asian Longhorned Beetle Prevention and Control Trees favored by the Asian longhorned beetle are predominantly maples, but infestations have also been discovered in horse-chestnuts, poplars, willows, elms, mulberries, and black locusts. Currently, there is no known practical chemical or biological defense against the Asian Longhorned Beetle and, in North America, they have few natural predators. How Trees Killed Are Killed by ALB The Asian longhorned beetle is a black insect with white speckles that grows a long antenna. The beetle chews its way into hardwood trees to lay eggs. The eggs produce larvae and those larvae tunnel deep under the bark and feed on living tree tissue. This feeding effectively cuts off the trees food supply and starves it to the point of death. How ALB Spreads Studies have shown that an Asian long-horned beetle can fly as far as several city blocks in search of a new host tree. The good news is that the beetle tends to lay eggs in the same tree from which they emerged as adults - they usually limit their flights under normal conditions. Prevention Unfortunately, there are no methods developed to practically prevent or control Asian longhorned beetle. If you detect the presence of ALB, the only thing that will help is to contact local forestry officials for consultation. They can take steps to contain the outbreak. The only way currently known to combat the Asian Longhorned Beetle is to destroy the infested trees. While cutting down mature trees is not a great solution for the tree owner and a tragedy, it is preferable to permitting the Asian longhorned beetle to spread.

Developing rigorous hypotheses Essay Example | Topics and Well Written Essays - 500 words

Developing rigorous hypotheses - Essay Example In effect, should deductive approach have been used exclusively in this study, the researcher would have had to focus the experiment on testing and examining the theory so that a firm theory or conclusion would be derived from the effect of the proposed scheme as a labelling scheme (Hardy & Bryman, 2004; Creswell, 2007). Meanwhile, it was not possible to use deductive approach alone, a reason for which no rigorous hypothesis was developed based on the experiment. As it has been explained earlier, the reason for refusing to use deductive approach alone, which would have called for the need to have a rigorous hypothesis was that there is no common test-bed based on which the performance, scalability and efficiency of labelling schemes can be assessed. Meanwhile, Sapsford & Jupp (2006) indicated that for a rigorous hypothesis to be set, based on which a deductive research will be carried out, it is important that there will be an easily substantiated framework or platform based on which the hypothesis can be tested. In the absence of such a framework or platform, the hypothesis set fails to be considered a rigorous hypothesis but only a guiding hypothesis that specifies to the researcher what needs to be achieved with the study. Also writing on research approaches, Riley et al. (2000) suggested that in such a scientific research as this where cannot be a rigorous hypothesis due to lack of a test-bed based on which the hypothesis will be justified, it is important that a combined approach that involves an inductive approach is used. It was based on this that the experimental framework used a combined approach comprising deductive approach and inductive approach. Yin (2009) explained an inductive research approach to be one which provides the researcher with greater flexibility and opportunity to modify the research emphasis depending on the accumulated findings throughout the research process. As a result of this, instead of exclusively basing on the

Sphalerite Essay Example | Topics and Well Written Essays - 1250 words

Sphalerite - Essay Example As sphalerite is soft and fragile it is mostly best left unset as collectors or museum pieces. Gem-quality material is usually a yellowish to honey brown, red to orange, or green There are a number of ways sphalerite is formed; bacteria also play a role in its formation. In the regions where there is low oxygen solution such as flooded tunnels the bacteria's take in zinc and sulfur from the water and combine them to create a byproduct of sphalerite known as sulfide, which reacts with the metals including zinc creating insoluble products. This build up of microbial precipitation by the bacteria have led to the discovery of large zinc sulfide deposits by the miners. The biofilm formed is grey in color and is further developed naturally to form sphalerite. Sphalerite is a cubic crystal with zinc and sulfur atoms tetrahedrally coordinated. This structure is similar to that of diamond. The hexagonal analogue is known as wurtzite structure. The lattice constant for zinc sulfide in the zincblende crystal structure is 0.596 nm, calculated from geometry and ionic radii of 0.074nm (zinc) and 0.184nm (sulfide). It forms ABCABC layers. Sphalerite is obtained from underground mining. ... It forms ABCABC layers. Mining Sphalerite is obtained from underground mining. It is the ore of zinc that is formed in veins which are layers of rocks and minerals formed underground. It is found in sedimentary, igneous and metamorphic rocks. Sphalarite accumulates in deposits which can extend far underground. Thus underground mining is most suitable; other methods would be too expensive and difficult. The underground excavation is determined by strip ratio method which is the total amount of waste materials that need to be removed in proportion the amount of ore. Thus minimum possible waste is extracted. The underground mine of sphalerite consist of sophisticated network of tunnels, shafts and equipments. It is entered through a shaft, a horizontal tunnel or an adit which is a horizontal entry way. There are several levels in the underground mine and sphalerite in mined in rooms called stopes. It is drilled and blasted out taking care of the ceiling so that the mine does not collapse. Sphalarite mining process involves a number of equipments. Continuous mining machines are used which cut through rocks and pull them up, even separating the unusable ore from waste rock all in one system. Dump trucks are used in the mine to carry material to appropriate locations to different parts of the mine. At times shuttle cars are also used. Today in the modern era mining is a highly technological and mechanized process. Sophisticated vehicles, rail systems and state-of-the-art drilling systems are bought from manufacturers and suppliers. Ventilation systems pump in fresh air while removing poisonous gases and dust. Also, the roof is supported by timber, concrete or even steel supports. Steel rods are
