Microbiology-2460 Lab-003 March 31‚2008 Lab Report-Escherichia coli Abstract The purpose for this lab report was to identify and inform of an unknown bacteria that has been causing a patient to have lower abdominal and pelvic pain. To obtain the identification of this unknown bacterium‚ several biochemical tests needed to be performed in order to prescribe the correct medication to treat and cure the symptoms. Introduction In a lab today‚ I am to identify an unknown bacterium that is

1. Compare the hash values calculated for example.txt that you documented during this lab. Explain in your own words why the hash values will change when the data is modified. They change to keep authentication and integrity. 2. Why are the MD5sum and SHA1sum hash values the same every time you calculate for the “example.txt” sample fi le? What if they were different when you re-calculated the hash value at the other end? These are the same to verify authentication and integrity.

Budget Introduction: This Albedo lab was created to help explain the process in which the Earth reflects solar energy back to space. The fraction of radiation reflected by an object is known as an albedo. In relation to the atmosphere‚ as solar radiation reaches certain colors on the surface of Earth‚ more radiation is absorbed by darker colors‚ which in turn decreases the solar radiation that reflects back to the atmosphere. If a person was interested in learning more about factors of

1200-1350 Abstract: In this lab the density of hand-made clay balls were calculated to understand how scientists model physical effects and to understand logarithmic plots. The hand-made balls ranged from diameters of 2cm to 6cm and were measured with vernier calipers by each member of the group. A total of 6 independent measures of each diameter were taken to establish uncertainty. The clay balls were then weighed on a gram slider and then recorded. The first data set was graphed mass (kg) against

Acetic acid Salicylic acid Aspirin (containing an (acetylsalicylic acid‚ -OH group) an ester) The use of acetic anhydride instead of acetic acid‚ however‚ is a better preparative method‚ because the anhydride with the water to form acetic acid tends to drive the reaction to the right as shown below. An acid catalyst also is used to speed up the reaction.

catalase is first introduced for 10seconds‚ the rate of reaction was highest because that was when substrate and enzyme concentration stayed the highest. As the experiment is prolonged‚ substrate concentration will only decrease as it is limited but the enzymes will continue to catalyze the lower concentration which leads to a lower rate. The amount of H2O2 consumed in the time course determination test never exceeded the baseline because it is expected that the baseline reacts to
