Introduction During the course of this lab‚ we explored whether or not certain processed foods contained Genetically Modified Organisms. Genetically modified food is an important subject in the world today. Ever since Flavr Savr came out with their tomatoes grown from genetically modified seeds in 1994 genetically modified foods has become ever more popular amongst distributors of produce (Mestel‚ 2013). The world’s population has grown by around one billion in the last decade (US Bureau of the

Exocytosis Lab Report Rough Draft Abstract: In Paramecium caudatum‚ trichocysts are 10^3 secretory vesicles that are released from the cytoplasm. We first observed how the presence of Alcian blue dye triggers normal secretion of trichocysts‚ and we then tested four different hypotheses in order to determine how the presence of Ca++ ions in the extracellular and intracellular environment affects the secretion of trichocysts. Our first our hypothesis tested whether extracellular calcium is

December 8‚ 2013 Soil Analysis Lab Report Intro: Soil is produced over hundreds of years through the weathering of rocks and the decomposition of organic material. Soil contains nutrients that are taken from decomposed animals and plants which turn to detritus. Nutrients such as nitrogen are added to the soil in these ways by organisms such as nitrogen fixing bacteria. Soil is important because it is the fuel to the plants that we need in order to survive and for all species to survive. Soil

this experiment‚ the amount of titrant dispensed correlates with the amount of copper; therefore‚ the amount of copper in brass was calculated by using the data recorded. In this experiment‚ the analyte is copper and the sample is brass. The concentration range of copper in brass is 50-95%. When copper reacts with iodide it forms a precipitate (CuI) along with iodine. As shown in this reaction: 2Cu2++ 4I- 2CuI(s) + I2. Iodine is formed because copper

A. Goal and Purpose: Session 1: In this lab‚ we will achieve a simple Friedel-Crafts alkylation of anthracene. The choice of anthracene as an aromatic substrate stems from two considerations. First‚ there is a question of regioselectivity. Second‚ anthracene and its derivatives are highly visible under UV light. Session 2: In this lab‚ we will complete a partial conversion of 9-acetylanthracene using m-chloroperoxybenzoic acid (mCPBA). We will also determine by NMR‚ the regiochemistry of the

Anxiety Lab Report Abstract: The aim of this study is to investigate the relationship between cognitive anxiety‚ somatic anxiety and self confidence in two different situations; non-stressful and stressful. It is to examine the effects on anxiety of a simple golf putting task. The stressor used in this experiment can be described as situational‚ namely the stressor of social comparison‚ the type of stressor that leads many performers to question their own ability which in turn evokes symptoms

of water as it goes from dilute to a more concentrated solution. Active transport is the movement of molecules from low concentration to high concentration against the concentration gradient. Energy is required for movement to occur. Water Balance- Salt concentration in blood depends on how much water is reabsorbed by kidneys and how much is excreted in urine. The concentration of salt in the blood can be higher if there is excess of sweating‚ not drinking enough water and eating salty food. Some
