Introductory Biology 1 Biology 1003 Fall Term 2011 Lab Number: 3 Title: Cell Energetics: Enzyme Role in Biological Reactions Name: Brandon Moore Student Number: 100819124 Lab day and time: Wednesday pm Date: Wednesday November 23‚ 2011 Introduction Enzymes are a key aspect in our everyday life and are a key to sustaining life. They are biological catalysts that help speed up the rate of reactions. They do this by lowering the activation energy of chemical reactions (Biology

Meiossis and Genetic Diversity in Sordaria Meiosis and Genetic Diversity in the Model Organism‚ Sordaria. By: Katie Fiorillo BIO110 Lab TA: Lauren Smith October 30‚ 2012 A. INTRODUCTION: In this lab‚ the organism Sordaria fimicola was used to explore factors contributing to genetic evolution of sexual reproduction. These organisms are found in “Evolution Canyons‚” which occur when two mountain slopes with very different climatic conditions congregate with a comparatively small valley

Presence of Alu element within PV92 on chromosome 18 in a mixed ethnical population and its connection with humans’ ancestral origins By Shiyu Song Biology 155Q LAB-A: 14:30-17:30 Dr. Jacob April 17th 2013 Abstract The Alu insertion (+) within PV92 on chromosome 16 usually reflects a person’s ancestral origin. This study aimed to find the correlation between the presences of Alu insertion (+) within PV92 on chromosome 16 within a population. We used PCR to detect the Alu insertions

Ketchup Lab Report Problem: People visiting fast food restaurants complained that ketchup was dripping onto their fingers and clothes. What could we do to insure that the ketchup will not drop all over the customers? Hypothesis: If I put one ketchup packet in a hotter bath then it will move faster down the styrofoam plate. Independent Variable: The temperature Dependent Variable: The viscosity of the ketchup’s “runniness” Constants: The type of ketchup

The purpose of the lab was to measure the effectiveness of antacids at neutralizing excess stomach acid. A neutralization reaction is when an acid and a base react to form water and salt. To illustrate‚ H+ hydrogen ions from the acid react with the hydroxide ions OH- from the base. Antacids are taken to relieve heartburn or indigestion caused by excess stomach acid. For instance‚ antacids such as alka-seltzers contain baking soda which is highly reactive with acids‚ settling the discomfort of indigestion

Osmosis Lab Research Question: In this lab‚ our goal was to look at the effects of different sucrose concentrations on osmosis in potatoes. Our research question was “How do the sugar levels affect the rate of osmosis in potatoes?”. Background Information: Solutions consist of solutes dissolved in a solvent. In all living organisms there are many different types of solutes including salts and sugars. The major solvent is water. There are different concentrations of solutes in various regions

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

Termite Lab Report The effect of ink on termite behavior Abstract Termites produce special chemicals within their bodies called pheromones. Because termites are usually found inside dark areas‚ pheromones help them communicate in these places. Past studies have suggested that ink inside ballpoint pens contains pheromones‚ causing termites to follow any trail created by the ink. If a pathway is drawn with an ink pen‚ then a termite will be attracted to the path and trace it due to the pheromones

Erin Gaudet SCI-220-01 Title: Hair Lab Object: Analyze hair samples Procedure: Same as in lab handout Results: See attached data sheet Conclusion: This type of lab analysis is important to the field of forensic science because you could link a person to a crime. The removal of hair from the body often denotes physical contact between a victim and perpetrator and hence a crime of a serious or violent nature. Forensic scientists would find this lab useful because they would be able to determine
