The Gene Lab 1. Introduction The purpose of this report is to inform dog breeders of a very common genetic disease known as Progressive retinal atrophy (PRA). The report will also inform buyers of the disease so they are aware of the disorder and they can check to dog’s pedigree for the disease. PRA could affect any dog‚ as a result of this it is recommended that the offspring should be examined by a board-certified veterinary ophthalmologist and screened for the existence of the disorder.

baking Yeast helps raise the dough and also yeast is used in the process of making wine.The Reason why yeast was chosen to was to see how yeast can metabolize different sugars and how much Co2 they release when when metabolizing.To test the yeast at the lab we used 4 different types of carbohydrates which are known as Glucose‚Lactose‚Sucrose‚and Starch.The main thing that make some of these carbohydrates different from each other is if it’s a Monosaccharide‚ Disaccharide‚or Polysaccharide. Monosaccharide

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

Stoichiometry lab 1 Purpose: The purpose of this lab is to find the limiting reactant‚ also to find the percentage yield and percentage purity of the reaction that happens between Calcium Chloride and Sodium Carbonate. The other purpose was to know how the reaction can be balanced and created. Hypothesis: In this lab we are going to see a precipitation reaction. This is a reaction where two soluble salts Sodium Carbonate and Calcium Chloride are added together and the result is the precipitation

Introduction: The purpose of this lab is to apply Mendel’s laws to predict the probability of the occurrence of a single event‚ of two independent events and of certain traits in offspring of parents exhibiting traits. Gregor Mendel was an Austrian monk in 1866‚ who studied how traits were passed using pea plants. From his studies of inheritance‚ he created three laws of inheritance: the law of dominance‚ the law of segregation‚ and the law of independent assortment. He called genes ‘’factors’’

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

Stoichiometry Lab Stoichiometry is the end result of adding up chemical elements that were involved in chemical reactions (http://dictionary.reference.com/browse/stoichiometry). The word stoichiometry was obtained from two greek words meaning element and measure. This explains the definition for the term. A chemist named Jeremias Benjamin Richter was the chemist responsible for first realizing what stoichiometry was (http://www.chemteam.info/Stoichiometry/What-is-Stoichiometry.html). In 1972

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

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
