Unknown Lab Report Unknown Organism #6 Ann Le (Phuoc) May 6‚ 2010 Dr. Carrington Microbiology Lab- MW 12:50 Le 1 I. Introduction My unknown organism #6 is Morganella morganii‚ which is a gram-negative bacillus rods commonly found in the environment and also in the intestinal tracts of humans‚ mammals‚ and reptiles as a normal flora. (3‚ 5) This bacterium Morganella morganii‚ was first discovered in the 1906 by a British bacteriologist named H. de R. Morgan. (2) Despite its wide

The effect of ATP (adenosine triphosphate) on bioluminescence in fireflies. Introduction Adenosine triphosphate‚ also known as ATP‚ is the supply of energy found in every cell that we need in order to do essentially everything (Anonymous‚ 2008). It is an energy source for biochemical reactions such as muscle contraction‚ active transport‚ molecular synthesis‚ and in fireflies‚ also known as lightening bugs‚ bioluminescence (Biology Book). Bioluminescence is the process in which living organisms

Maryely Ramirez Professor Theresa Sterner Bio Lab 105 04 November 2013 The Effects Environmental Temperature and pH have on the Activity of Porcine Pancreatic Amylase Introduction There are many types of enzymes and each has a specific job. Enzymes are particular types of proteins that help to speed up some reactions‚ such as reactants going to products. One of them is the amylase enzyme. Amylases are found in saliva‚ and pancreatic secretions of the small intestine. The function of amylase is

Erin Gaudet SCI-220-01 Title: Hair Lab Object: Analyze hair samples Procedure: Same as in lab handout Results: See attached data sheet Conclusion: This type of lab analysis is important to the field of forensic science because you could link a person to a crime. The removal of hair from the body often denotes physical contact between a victim and perpetrator and hence a crime of a serious or violent nature. Forensic scientists would find this lab useful because they would be able to determine

The objective of this lab was to recreate the color profile of a given solution. In this case‚ the solution was Powerade. The final solution should match the absorbance values at the peak wavelengths (420nm and 628nm) in Powerade. This lab was done using deionized water‚ FD&C Blue #1‚ FD&C Yellow #5‚ FD&C Red #40‚ and a spectrometer. To obtain the correct color profile‚ FD&C Blue #1 and FD&C Yellow #5 were utilized in the sample solutions. The experiment was conducted over two days; the first day

The purpose of the lab is to identify the compound based on a constant composition by performing a serious of tests. The hydrate is solid crystals compound and appears to be dry: since an ionic compound (salt) is crystallized from an aqueous solution (water)‚ by heating the hydrate the water is released from ionic structure; therefore it is possible to measure the weight of the ionic compound and calculate its ratio to the liquid in the hydrate. The goal of the lab is to establish the identity

Morgan Kimmerle Monday Lab Dr. McCorkell Abstract The purpose of this study was to cross and analyze the reciprocal crosses of wild flies and mutant flies. In this lab Drosophila melanogaster commonly known as fruit flies were used to understand some important genetic principles that were once proposed by Gregor Mendel. Mutant traits can be autosomal dominant‚ autosomal recessive traits‚ or even sex-linked dominant and sex-linked recessive. F1 and F2 generations were obtained by performing

The lab required pressing two toothpicks against the skin simultaneously. It was difficult to press down both toothpicks at the same time and this skewed the results. When the toothpicks weren’t pressed down at the same time‚ it felt like one point‚ then another

Introduction In the amylase lab‚ it was being tested if amylase‚ an enzyme found in saliva‚ would be denatured by being put in an acid or high temperatures. This lab is about denaturing amylase. It is tested by exposing it to pH and temperature changes. It is then mixed with Benedict’s solution‚ is a solution that changes color from blue to reddish brown when maltose is present. Amylase breaks starch into maltose‚ so is the amylase isn’t denatured‚ it should change colors. Amylase is an enzyme
