organism used for this experiment was Saccharomyces cerevisiae (S. cerevisiae) which is often called baker’s yeast. S. cerevisiae has several characteristics that make it an ideal organism to use in experiments. S. cerevisiae is a single-celled eukaryote capable of reproducing through mitosis or sporulation. This means that the yeast has both a haploid and a diploid stage. In yeast‚ the haploid cells are n=16 and the diploid cells are 2n=32. S. cerevisiae has two haploid mating types MATɑ and MATa. When

Beer Lambert Law Lab Purpose: The purpose of this lab is to prove the Beer Lambert Law experimentally. The various solutions used for this experiment are tap water mixed with food colouring‚ Introduction: The Beer Lambert Law shows the relation between absorbance of light of an object‚ the molar absorptivity‚ the concentration of the substance‚ and the distance the light travels. The Beer Lambert Law states that there is a linear relationship between the concentration of a solution and the

Name: Taylor Wright Lab Partners: Cody‚ Jeremy‚ Haly‚ Eric‚ Brody Date: October 14th Class: Chemistry 20 Charles’ Law Lab Introduction: The purpose of this investigation is to demonstrate how water temperature affects the volume of a balloon. According to Charles’ Law‚ temperature and volume increase proportionally‚ as long as chemical amount and pressure remain the same. Research Question: How does the volume of a balloon react to changing temperatures? Hypothesis: If we increase the temperature

Newton’s 2nd Law Lab Introduction: The purpose of this lab was to prove Newton’s 2nd Law; which states accelerate equals force divided by mass (a=F/m). During this lab we were trying to find out the relationship between acceleration‚ force‚ and mass by using a air track‚ glider with picket fence‚ and photogates. Before I did the lab‚ I had already knew that acceleration‚ force‚ and mass were related. I just didn’t know how they were related. When recording the results of this lab we had to record

Charles’s Law – Lab Report Charles’ Law: Assuming that pressure remains constant‚ the volume and absolute temperature of a certain quantity of a gas are directly proportional. Mathematically‚ this can be represented as: Temperature = Constant x Volume or Volume = Constant x Temperature or Volume/Temperature = Constant Substituting in variables‚ the formula is: V/T=K Because the formula is equal to a constant‚ it is possible to solve for a change in volume or temperature using a proportion

Newton’s Second Law Lab Preliminary Questions 1. When you push on an object‚ the magnitude of the force on the object directly affects it’s motion. If you push harder on the object‚ it’s motion is larger. 2. If we have a bowling ball‚ and a baseball each suspended from a different rope‚ and hit each ball with a full swing of a baseball bat‚ the ball that will have the greatest amount of change in it’s motion will be the baseball. This is true because the baseball has a smaller mass than a bowling
