Plate Tectonics Ever since the beginning on time‚ Humans believed the ground is solid and immobile. But this is not true whatsoever. The Earth is every-changing and continually in motion. The stability of the Earth is not at all what we think it is. Thinking about the rotational axis of the Earth‚ and possibly of what the Earth may become at a certain point in time‚ has a great influence on understanding all aspects of living things‚ either in the past‚ present‚ or future. The study of Plate

November 5‚ 2014 Bioinformatics Leigh Ann Santana DNA Extraction Lab DNA extraction is an important process because the DNA first needs to be purified away from proteins and other cellular contaminants. Cell are needed‚ because that is where the DNA is located. Inside almost every cell in our bodies is a nucleus‚ and inside each nucleus is about two meters of DNA. The following steps are needed to purify DNA from a cheek swab. Collect cheek cells‚ Burst cells open to release DNA‚ separate DNA

Essay Honey Spot By Jack Davis Jack Davis uses many dramatic conventions in his play‚ Honey Spot. The three main devices focused on in this essay are the interlude‚ tension and dramatic irony. The interlude informs the audience about what is happening without any dialogue. Tension is created by language or dialogue or by actions. Dramatic Irony is a strange or unusual coincidence. Normally the character in the play would not be aware of the coincidence‚ but the audience is. In this paragraph

EXECUTIVE SUMMARY: The main objective of this project was to carry out a design on the Propane distillation column for a process that produces 1‚3 Butadiene. The raw materials used are Butane‚ Oxygen and Water and the process capacity is 100 000 tonnes per annum nominal. In the previous work it was stated that the plant is located in China. The main location of the plant is in the capital city of the Gansu Provence‚ Lanzhou. This was decided as the location over other provinces due to the excellent

Expt. 8.1 Thin Layer Chromatography (TLC) Analysis of Analgesics Krista Jinks CH 211L Section F 10/27/14 I. Abstract: The objective of this experiment was to analyze analgesic tablets by TLC to determine what analgesics they contain. The analgesics that could be in the tablets included ibuprofen‚ acetaminophen‚ aspirin‚ and caffeine. Through the use of TLC‚ unknown substance #62 was found to be Bayer Aspirin because it only contained aspirin. II. Introduction: 1. Briefly describe

Discussion: Extraction and crystallization- The purpose of this lab was to extract and crystallize compounds in a mixture using acids and bases. 1 gram of the unknown was dissolved into 30 mL of ethyl acetate. The mixture was then transferred to a separatory funnel. Using aqueous solutions of different pH we were able to separate organic acids‚ bases and neutral compounds from each other. Using three 10 mL portions of HCl‚ we reacted the HCl with the base in solution. This made it possible to

technique of thin-layer chromatography‚ or TLC. The active ingredients of Excedrin were caffeine‚ acetaminophen‚ and aspirin with Rf values of 0.11‚ 0.38‚ and 0.61‚ respectively. The lone active ingredient of Tylenol was acetaminophen with an Rf value of 0.39. The elution sequence obtained in the experiment is as follows: ibuprofen (least polar)‚ acetylsalicylic acid‚ acetaminophen‚ and caffeine (most polar). Purpose of Experiment: The objective of this experiment is to determine the active ingredients
