    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

    LAB Report #3 Introduction: In this lab we have focus on Isolation of bacteria from environment. Microorganisms are found throughout the environment: in the air and water; on the surface of any object such as clothes‚ walls‚ furniture; in soil and dust; and on and in our own bodies (skin and mucous membranes). In order to demonstrate the ubiquity and diversity of microbes in the environment‚ samples from immediate areas of the environment and/or from your body will be obtained and cultured

    Enzyme Activity Over Different Concentrations and Effects The goals of this experiment were to examine the effectively of enzymes on samples of different enzyme concentrations and substrate concentrations. In addition‚ the experiment tested how effective enzymes are on samples of pH levels and temperature levels. A. Effect of Enzyme Concentration Hypothesis: With half as much enzyme concentration then the reaction rate will be half as much than when the enzyme concentration is equal

    affecting Enzyme Activity: The effect of pH on enzyme activity Background Knowledge: An enzyme is a biological catalyst – which speeds up the reaction rate‚ without itself getting altered. Enzymes are proteins with long polypeptide chains that are folded up into three – dimensional shapes. An enzyme acts on a substrate to convert the substrate into a product useful for the organism.The active site is a special region on the surface of the enzyme where the substrate binds to the enzyme.

    Lab Report: Halogen Reactions Purpose: This experiment will allow for exploration into some of the properties of Group 17 elements (halogens) and their compounds. More specifically‚ the solubility properties of these halogens will be used to predict their reactions. The relative electronegativities of the halogens will be determined. Halides‚such as Cl-‚ Br-‚ and I- will be used to make these determinations. Because this lab is qualitative rather than quantitative‚ there are no calculation
