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

exists in our small intestine and our small intestine uses acid to break down food. The result from the lab prove my hypothesis correct because lactase worked well at body temperature and it also worked well at pH of 4.5 to 5.5 mg/dl proving that lactase works best at an acidic pH number. The lab shows that the highest amount of glucose is made by temperatures close to body temperature. In our our lab‚ we found that at 35 °C 500 mg/dl glucose was produced‚ which was the highest number of glucose that

AIM: Finding the gravitational field strength by using a simple harmonic motion of a spring and slotted masses. INTRODUCTION: When a mass suspended from a spring is displaced‚ due to the acceleration‚ kg s-2‚ from its equilibrium and released it will oscillate up and down with a kind of motion called simple harmonic motion‚ shm. The period (T)‚ time taken to measure for one complete oscillation‚ of this motion is: m/kg =

A PIECE OF BREAD (by Mrs. Wilma C. Aruelo) It’s been long years of sufferings and now I stood at the bar of justice with my pale young face "Am I guilty or not guilty?" It’s a question that always lingers on my mind. "I will tell you just how it was. My father and mother were dead. My little brothers and sisters were hungry and asked me for bread. At first I earned the bread by working hard all day. But somehow‚ the times were hard and the work fell all away. I could get

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

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

BREAD MAKING TIME LINE Depending on the type of yeast you are using the steps to making bread will vary. Using the basic bread dough recipe‚ this time line is based on using dry active yeast. I am also basing this time line on the straight dough method which is the direct method of making bread. STEP 1 To make your dough‚ your ingredients must be accurately measured and weighed as well as be the appropriate temperature. Wet ingredients are usually weighed rather than measured to guarantee
