Introduction Chemical kinetics is the study of reaction rates. A reaction rate is the speed of the change in either reactants or products over a period of time. General kinetic rate equation is: Where [A] and [B] are the concentration of the species in the reaction. The variable k is the rate constant‚ which is a function of time and catalyst presence. The variables m and n are the order of reaction for their respective species concentration. The higher the value of the reaction order the

Fly Lab Shannon Ladd Introduction: Famers and herders have been selectively breeding their plans and animals to produce more useful hybrids for thousands of years. It was somewhat of a hit or miss process since the actual mechanisms governing inheritance were unknown. Knowledge of these genetic mechanisms finally came as a result of careful laboratory breeding experiments carried out over the last century and a half. A contributing geneticist named Gregor Mendel (1822-1884)‚ discovered through

Should Genetic Engineering Be Controlled by Law? “Just as the success of a corporate body in making money need not set the human condition ahead‚ neither does every scientific advance automatically make our lives more meaningful” ( Professor George Wald‚ Noble Prize winning biologist‚ The Dangers of Genetic Engineeering 1976‚ p.45) . Genetic engineering is the direct manipulation of an organism’s genes. It uses the techniques of molecular cloning and transformation to alter the

In this lab we are going to be observing the decomposition of piglets over a month’s time. There are theory questions that have been given to us before and after the lab. We look back at our original theory to see where we went wrong‚ and then correct it. The lab was disgusting‚ surprising‚ and very interesting. The first questioned to be answered is which piglet decomposes faster‚ a piglet that is in its natural state‚ that is burnt‚ that is buried‚ and that is buried in a wooden box? With

After the completion of the Human Genome Project‚ scope for genetic engineering was greatly expanded. Every part of human DNA was mapped and recorded for its role in the DNA. This also made changes in DNA possible‚ allowing scientists to remove or fix any mutations that could lead to harmful consequences. Due to the success of the project it is possible that in a few years couples may even be able to design their children by picking not only their children’s physical appearance but also their children’s

GENETICS EXAM I You may write all over this exam‚ but only your #2 pencil answers on the blue opscan sheets will be graded. Bubble-in only one answer for each question; there are no purposely tricky questions. If you think you have found a trick question or a question is not clear‚ ASK when leaving the exam room. You may leave when you are done. 1. Chromosomes‚ colored bodies‚ are composed of proteins and DNA; so are chromatids. At metaphase I there are 46 chromosomes aligned

There are a wide variety of genetic disorders that parents face during pregnancy. Parents are faced with the terrifying news of the disorders that doctors diagnosis their unborn children. In some cases‚ certain disorders are not discovered until after the birth of the new baby. Due to the fact that there are a wide variety of genetic disorders‚ there are also different ways these disorders can be detected‚ as well as the different ways they affect the unborn baby‚ the mother‚ and the treatment plans

Their genetic makeup allows them advantages over non-gingers as well as disadvantages. Inevitably‚ there are also plenty of misconceptions and stereotypes about redheaded people that have led to taunting‚ mistrust‚ and even violence throughout history. If you have ever wondered how to become a ginger‚ sit down because Zoe is about to give you a step by step guide. Step one: You must have the gene that causes red hair. This gene is recessive and comes from the MC1R‚ which is a genetic mutation

Effects of Crossing Over in Sordaria fimicola Abstract Sexual reproduction in organisms is a cause for genetic variation. This can be seen through the process of meiosis in Sordaria fimicola because of the effects of crossing over and independent assortment that occur in meiosis I. Before performing this experiment we hypothesized that we would be able to see that crossing over did indeed occur in the S. fimicola. We tested our hypothesis by growing our own culture and observing it under a

It can tear a family down and ruin a person’s life. But would knowing you have it early-on be beneficial or devastating? Controversy will always surround the idea of genetic testing. Knowing you carry the gene for Alzheimer’s can help prepare yourself for your overwhelming future. If you have close friends or family‚ you could also help prepare them and educate them about your disease. On the same note‚ if you have a
