Biology 102 Lab Report: Ventilation and Oxygen Consumption in Fish Methods: The lab consists of two experiments repeated over a period one hour with fifteen minutes interval‚ in order to determine the effect of weight and temperature on ventilation and oxygen consumption of Carassius auratus‚ commonly known as goldfish. Each experiment was carried out by five groups. Measurement of ventilation was determined by recording operculum movement of the fish. Oxygen consumption was measured using oxygen

Molecular Biology Lab Report Mapping DNA using Restriction Enzymes Ava II and Pvu II to cut Bacterial DNA Abstract The objective of this project is to map bacterial DNA‚ which is derived from E. coli‚ using restriction endonucleases with gel electrophoresis. The DNA fragments‚ after cutting has occurred‚ are separated using agarose gel electrophoresis. The DNA fragments are placed in the gel‚ and an electric current is run through the matrix of the gel-like agarose. Migration of the fragments

Abstract The objective of this lab was to measure the amount of protein from a piece of beef liver . This was done by taking the liver‚ blending it and then using a centrifuge to separate the supernatant from the pellet. Once that was completed‚ ammonium sulfate was added to the supernatant‚ chilled and then spun for a second time. Next‚ 20 mL of water is added to the pellet‚ stirred and the volume was recorded. The teacher calculated the total mass of liver to be 10.098g. Lastly a spectronic

Labset Three Worksheet 1. What is a carbohydrate profile? Why are they used as a diagnostic or identifying tool? (2) Carbohydrate profiles are specific information on the type and amount of carbohydrate that a product contains. It is used to identify and differentiate two closely related species. 2. What are the carbohydrate profiles of the organisms you tested? (2) The yeast carbohydrate profile came out with glucose and fructose positive and Mannitol negative. The staph epidermidis

Sang Kim Enzyme Catalyst Purpose/Problem: There are four parts to the Enzyme Catalyst lab - Activity A‚ B‚ C‚ and D. In activity A‚ the characteristics of enzyme actions will be observed. The main purposes are to determine the rate of an enzyme catalyzed reaction‚ to study the characteristics of an enzyme mediated reaction‚ and to observe the effect of heat on enzyme activity. The purpose of activity B is to use the Titration Protocol to determine the initial amount of H 2O2 present

Lab #2: Energy in Cell Virtual Lab - Week 3 NAME: ________________________________________ 1. What is the importance of the light and dark reactions in photosynthesis? Photosynthesis works by absorbing light. Our sun gives off energy and the chlorophyll from the plant absorb this energy. The energy is then used to separate water into hydrogen and oxygen and then they combine hydrogen and carbon dioxide to make sugars. 2. What happens to food energy during photosynthesis? During

Michelle Kim 2012.1.20 Biology Iso-osmolar Concentration of Carrot Cells Lab INTRODUCTION For a more thorough understanding of this lab introduction‚ the concepts of‚ iso osmolar‚ membrane‚ equilibrium‚ and concentration gradient evaluated. Iso osmolar can be known as the point in which the substance of experimentation faces no change despite the amount of solute inside the solvent( because the solvent and solute concentration is equal. This is where the line on a graph would cross on the
