determine whether or not a chemical reaction occurred after the mixing of various chemicals. The evolution of a gas‚ the formation of precipitation‚ and the change of temperature or color are all indicative of a chemical reaction. It was assumed that a reaction did not take place if the mixture of chemicals exhibited none of these characteristics. Several precipitation‚ complex-ion formation‚ redox‚ and acid-base reactions were performed. Redox: Decomposition Reactions In a 13 x 100 mm test tube‚ 2 mL

Microbiology Laboratory Report Identification of Unknown Bacteria 03/10/05- 04/01/05 Authors: Richard Hendricks‚ Jessica Prebish; NMU Abstract: Broth culture 16 was randomly selected by our group and subjected to qualitative tests for taxonomic identification. The culture did appear homogenous throughout the testing period and is currently retained by Northern Michigan University’s department of Microbiology. We suggest that culture 16 is an example of Escherichia coli. Background: Techniques

Chapter I History Expert Testimony DNA Forensics At every crime scene there always some evidence left behind. Forensic Science is application of science to the law‚ everything from finger prints blood‚ hair to all in DNA analysis is used. It is the basic root to solving crimes. Forensic science involves many factors relating to the human body and has the most accurate type of convincing when it comes down in the court room. This in return gives forensics specialists to utilize different hypothesis

How Enzymes Work In Different Environments By Sarah Smith Biology1111 October 20‚ 2011 Lab Partner: Nellie Greer ABSTRACT Peroxidase is an enzyme found in potatoes that catalyzes the breakdown of hydrogen peroxide‚ H2O2‚ into O2 gas and water. We examined the different pH environments that can affect the enzyme activity during the breakdown of H2O2. In order to do this‚ we added different levels of pH‚ low‚ medium‚ and high‚ into different test tubes with the enzyme and H2O2‚

Mallory Charland February 9‚ 2015 Mutations of E. coli Lab Report Advanced Biology Deducing Mutations of the Lac Operon of E. coli Abstract: In this lab we determined a possible mutation in unique bacterial strains of E. coli by observing the proper responses of wild type E. coli Lac Operon as a control group. Mutated strains of E. coli were placed in four test tubes‚ each containing a different substance (lactose‚ glucose‚ water and lactose and glucose)

Lab Report 3 In this lab‚ we will take a trip to the planetarium lab and will learn about Right ascension and declination‚ and altitude and zenith. After looking at the different points shown‚ we will log the altitude and zenith in the chart in our lab manual. Now we will look at the same points and label the right ascension and declination. Then we will learn about the easiest way to locate the star Polaris. As we started the first program‚ we answered a few questions to make sure we knew
