When Chemicals React! Mr. Bell’s honors level chemistry class conducted an experiment during their lab demonstrations‚ this consisted of elements such as phosphorus and calcium chloride in their experiment. This along with another hydrogen based sunstance produced‚ what looked like a pinkish-looking substance inside of their flasks that were at their lab stations. Sophmore Kelly Caudel said‚ “ I actualley enjoy doing the experiments in this class‚ because it gives us a chance to get away from

Staphylococcus aureus AATCC 6538 gram positive (+ve)). The result was taken after 4 hours‚ 8 hours and after 24 hours. 2.4. Physico mechanical measurments: 2.4.1. Tensile strength and elongation: The tensile strength and elongation of treated fabrics were measured according to ASTM procedure D/3822 (14). 2.4.2. Stiffness test: The stiffness of the treated fabrics was measured according to ASTM procedure D/1388(9).

Bioinformatics Lab Report Hypothetical Phylogenetic Tree: Using a cladistic approach‚ we constructed a hypothetical phylogenetic tree of many different plant taxa by comparing their morphologies. We first decided to sort the various types of plants into groups based on morphological features. After sorting these plants into five different groups we began to determine how the plants differed from eachother in the group and what features set them apart. From this we started to create

Lab Report Enzymes (must be typed) Name: Amanda Gallegos Date: 2/15/15 Section: BIOL 101GL What is the Hypothesis of this experiment? (3 points) -The highest temperature will affect the reaction rate of enzymes. What is the dependent variable? (1 point) -Change of rate/product/color/absorbency. What is the independent variable? (1 pt) -The temperature. Explain in detail the procedure that you followed (including amount of substrate‚ enzyme etc‚ and the whole procedure including incubation times)

hemolysis time between methanol and ethanol was not statistically significant (P = 0.0666‚ t = 2.0577‚ df = 10); the same result was found between the results of ethanol and propanol (P = 0.0888‚ t = 1.8851‚ df = 10). The difference between hemolysis time for methanol and propanol‚ however‚ was found to be statistically significant (P < 0.05‚ t = 2.0577‚ df = 10)‚ as was the difference between urea and ethylene glycol hemolysis time (P < 0.001‚ t = 20.9104‚ df = 10). The results were expected to show statistically

the percent yield by dividing the expected yield‚ the amount of product that should be produced based on your stoichiometric calculations‚ by the actual yield‚ the amount of product that is experimentally obtained from a chemical reaction. In this lab‚ I have determined the reaction for mixing two reactants together; I measured out 0.005 moles of each reactant‚ lead (II) nitrate and potassium chromate. I dissolved‚ mixed‚ and made them react to make products; I compared the mass of the two reactants

Enzyme Lab Report Introduction The objective of this experiment was to determine if changes in pH or temperature affected the activity of enzymes‚ specifically the enzyme sucrase. Enzymes are protein molecules that act as biological catalysts to increase the speed of the reaction or to lower the activation energy of that reaction. However‚ the activity of an enzyme can be affected by physical factors such as pH and temperature because these factors alter the structure of the enzyme (Freeman‚ 2011)

Themes of W.H. Auden’s "The Unknown Citizen" Conformity and Anonymity in the Modern World "Social Security Number? Birth date? Nine digit telephone number starting with area code? Mother’s Maiden Name?" In many ways‚ we are simply faceless numbers to modern society‚ not individuals with feelings and emotions and dreams. W.H. Auden‚ a well-known English poet and dramatist‚ discusses this important theme in his poem "An Unknown Soldier." Auden‚ being a modernist‚ is concerned with this modern idea
