Staphylococcus aureus‚ otherwise known as Staph‚ is a bacterium that has naturally acquired resistance to many current antibiotics. Specifically‚ the MRSA (methicillin-resistant Staphylococcus aureus) strain has acquired resistance to methicillin. Staph frequently colonizes in human nasal passages‚ which serve as reservoirs for transmission. The following texts focus on Staph’s nasal colonization and mode of transmission‚ inspired by the research of Dr. Alexander Cole at UCF’s Burnett School of Biomedical

. Yes‚ comparably to TLC plate 2 and 3. The benzophenone is more neutral but as the same time its nonpolar‚ being that Silica gel in TLC 2 was polar and the solvent ethyl acetate-hexane is non-polar it moved relatively with the solvent. The stationary phase in TLC 3‚ alumina is non polar and the solvent ethyl acetate is polar so from the ideal that polar does not attract non-polar benzophenone stick stronger to alumina non-polar rather than moving up with polar solvent ethyl acetate as it did in

Review 2: Text DNA is a very special and important molecule that is in our life‚ DNA is found in the nucleus. DNA stores the data needed to make poly peptides‚then data in a nucleic acid is transferred to messenger RNA‚ which escapes the nucleus into a protein. According to the DNA and protein article DNA is used in many things but DNA is used to make pol-peptides. They are another word for proteins. When a cell makes a protein the direction are resembled from the part of an DNA. DNA strand and transcript

Amoxicillin Amoxicillin is a penicillin antibiotic. It fights bacteria in your body. Amoxicillin is used to treat many different types of infections caused by bacteria‚ such as ear infections‚ bladder infections‚ pneumonia‚ gonorrhea‚ and E. coli or salmonella infection. Amoxicillin is also sometimes used together with another antibiotic called clarithromycin (Biaxin) to treat stomach ulcers caused by Helicobacter pylori infection. This combination is sometimes used with a stomach acid reducer

The Titration of a Basic Solution of Unknown Molarity with a Standard Hydrochloric Acid Solution Abstract The aim of the experiment was how to determine the molarity of a solution. My hypothesis was if I have to determine the molarity of a NaOH solution‚ then I would have to use a standard solution of HCl solution because I would need to neutralize each other to determine the concentration of the solution of NaOH. The method that I used for this experiment was titration. Titration helped

Kayla Adkins Forensic Chemistry Exam 2 I have been honest and observed no dishonesty. 1. In specific detail‚ describe a published procedure for the definitive identification of Heroin utilizing gas chromatography-mass spectroscopy (GCMS). Heroin is a white crystalline powder with no odor and a bitter taste. It is a derivative of morphine in that the –OH (hydroxyl group) is replaced by an acetyl group‚ -OCOCH3 and has a molecular formula is C21H23NO5 with a molecular weight of 369.42

EXP-10 CHEM 233L SYNTHESIS OF p-BROMOANILINE Introduction: In this experiment‚ p-bromoaniline was synthesized in three steps starting from aniline. Since the amino group of aniline is a strong activator of aromatic ring‚ direct bromination is impractical (equation 1). In order to make a desired product‚ amino group needed to be protected as the acetamide which also maintained ortho and para position but slowed down the rate of reaction (equation 2). Slow reaction rate would increase

Writing a Synthesis Essay/Paper A synthesis essay draws on two or more sources and combines their ideas into a coherent whole. The word "synthesis" means to combine related things in a meaningful way‚ with a specific purpose in mind. When you synthesize‚ you blend the parts in such a way that you create something that is worth more than merely the sum of the parts. For our purposes‚ synthesis means putting together the arguments of various authors in a way that sheds new light on the discussion

Minimum Wage For years there has been disagreement over whether the minimum wage should be raised or not. Some believe that by raising the minimum wage‚ many Americans would be able to rise above the poverty line and have access to their dream.
