    The mean hemolysis times of sheep erythrocytes in 0.3 M urea‚ thiourea‚ methanol‚ ethanol‚ propanol‚ ethylene glycol‚ diethylene glycol‚ and triethylene glycol were calculated‚ and paired‚ two-tailed t-tests were conducted to determine statistical significance. It was found that the difference in 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

    The Catalase Lab Stephen Human Anatomy & Physiology 9/30/12 Problem- How do different environments affect the reactivity of catalase? Hypothesis- If more catalase is added then more oxygen (kPa) will be produced in a faster rate because there is more catalase to react upon. If less catalase is added then less oxygen (kPa) will be produced in a slower rate because there is less catalase to react upon. Variable- Independent- Amount of Catalase (Filter Paper) Dependent- Amount of

    Aim: To Find and test the Iron content in different food sources INTRODUCTION: A Redox titration was used in order to perform this experiment. Reduction/oxidation (redox) process occurs when electrons are transferred from a donor species (the reducing agent) to another acceptor species (the oxidizing agent). It happens between an analyte and a titrant. A redox titration is done just as a normal titration is done‚ however instead of titrating an acid against a base‚ an oxidizing agent is titrated

    Botany Lab ------------------------------------------------- Introduction This study observed the effects of different body fluids and solutions relative to breaking down bacteria‚ specifically in the human body. The enzymes we studied‚ lysozomes‚ help the body lyse‚ or break down bacteria by targeting peptidoglycan in bacterial walls. The solutions and fluids studied were saliva‚ mucus‚ tears‚ a stock solution of lysozomes‚ and distilled water. The solutions were placed in agar containing Micrococcus
