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

fits the shape of the active site‚ the enzyme will alters its shape so the active site embraces the substrate and maintains a firm grip‚ known as induced fit. This allows for great variations of enzymes. Abstract In this experiment‚ my lab partners and I tested how time effects a catalase reaction. The amount of hydrogen peroxide was recorded after the reaction for the certain time given has taken place. We used sulfuric acid to stop the reaction with the catalase from occurring. This process is known

LAB 1 1. Describe the function of the following pieces of safety equipment and how each might be used: (10 points) a. Eye Wash (2 points) The eyewash fountain is used to rinse chemical splashes off the eyes. They are used by rinsing the eyes 15 to 30 minutes with water. b. Fire Blanket (2 points) Fire blankets are used to extinguish small fires. They are used by covering the small fires with the blankets until it extinguishes. c. Shower (2 points) Safety showers were made to eliminate any

Lab Report Janice Chisholm SCI207: Dependence of Man on the Environment Instructor: Lee Ott April 28‚ 2013 1. What patterns do you observe on the information table 4? While observing the information in table 4‚ it appears that the number of fish changes from time to time and the oxygen increases and / or decreases when this occurs. 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water?

Keep swirling the solution until a pink color is visible throughout from the phenolphthalein. 8) If over titration occurs ask the teacher for further instruction. 9) Write down the final volume in the NaOH buret 10) Subtract the final volume of NaOH from the initial volume. 11) Repeat this process at least twice more.

Tim Readmond AP Biology Lab Report I. Title a. Modeling Diffusion and Osmosis II. Introduction a. If one places a 1.0 M solution of glucose inside a bag and then places that bag into a beaker containing a 1.0 M solution of sucrose‚ the percent of mass lost in the bag is 10.5%. The solution in the bag is hypertonic while the solution in the beaker is hypertonic‚ which is why water moves from the bag to the beaker and the bag loses mass. b. The purpose of this experiment is to see whether

II. Genetic variation is accounted for in Meiosis I due to crossing over. No formal hypothesis was made due to the fact that this lab was a simulation and observation of prior knowledge. The lab did not go as expected for prophase was supposed to be the second longest phase in exercise 3A but Metaphase ended up with the higher percentage (Table 3.1). Because this lab was solely based on observation‚ there was little space for error‚ but as mentioned above‚ metaphase ended up with the higher percentage
