ABSTRACT: Two separate variables were hypothesized and tested within the confines of the experiment on their effects on the productivity of lactase enzyme. The measurement of light absorbance levels of different solutions based on both the concentration of o-nitrophenol (ONP) as well as the pH of the solution tested. To begin with‚ differing concentrations of ONP were tested to find the absorbance levels of ONP. Three different pH values‚ 5‚ 6‚ and 7‚ in solution‚ were tested over a period of 8

In the following Mika and Myself reviewed the new Asus Crosshair V Formula ZAM3. Due to the relative newness of this motherboard there are several IO connections that are not illustrated in our Diagrams. However as you can see we identified most of all the major IO ports in Diagram one and two. So let’s start with what IO ports

Josh P. AP Biology 12-10-13 Lab Writeup The Effect of Transformation of pGLO in Bacteria Background/Objectives/Hypothesis: Genetic transformation is a process that primarily is inserting new DNA into an organism to change that organism’s trait. This process has many useful benefits when used correctly in different organisms. In this lab‚ bacteria was transformed by inserting DNA for Green Fluorescent Proteins. The DNA for these proteins were taken from bioluminescent jellyfish Aequorea

EXPERIMENT 3: IDENTIFICATION OF FOOD CONSTITUENTS IN MILK. INTRODUCTION: In this experiment two milk samples are given and its compositions are tested using different methods such as using benedict solution to test the presence of reducing sugar‚ using copper II sulphate to test the presence of protein‚ using K3( to test the presence of fat. However in this experiment‚ not only are the milk tested for its composition‚ the amount of the particular substance such as reducing sugar‚ protein and

Lab 3: Bromination of Acetanilide CHEM 2110 Hassan Alsaleh 0525970 Due date :11/02/2015 Q1: To find the limiting reagent we need to find the number of moles of acetanilide‚ and the number of moles of Bromine. Mass of Acetanilide used = 0.67g Molar mass of Acetanilide = 135.16g/mol[1] Number of moles of Acetanilide = (0.67g) / (135.16g/mol) = 0‚005 mols Volume of Bromine = 0.25ml Density of Bromine = 3.103 g/ml[2] Mass of Bromine = (0.25ml) X (3.103g/ml) = 0.78g Molar mass of Bromine

AP Biology Sunday‚ October 24‚ 2010 Enzyme Lab Write-Up Purpose: To observe how an enzyme affect the speed of chemical reaction. To describe how the concentration of an enzyme affects its ability to work. Hypothesis: Depending on the concentration of the catalase which the disk is soaked in‚ it will have a direct correlation on the rate of hydrogen peroxide being broken down into oxygen gas. Prediction: Since the rate of reaction can be lowered by the addition of
