Bio Lab Report Erica Patterson September 10‚2013 Intro to cellular and molecular Biology Lab Abstract: In the Biology Laboratory Manual by Darrell S. Vodopich and Randy Moore are results to a similar experiment. The studied the hypothesis of carbon dioxide production by yeast fed sugar is not significantly different than the carbon dioxide production by the yeast fed in protein. Their hypothesis is the one that has helped formulate ours. We also will be answering the same to questions “What

Science Lab on Electromagnets By Caitlin Hendriks Factors that Affect the Strength of an Electromagnet Purpose: To test how two different factors‚ the number of loops and the current intensity‚ affect the strength of the magnetic field of an electromagnet. Materials: Power pack‚ 4 connecting wires‚ switch‚ ammeter‚ paperclips‚ iron nail‚ copper wire. PART A: TESTING THE NUMBER OF LOOPS Procedure: 1. Create an

Title: The Effect of Varying Amounts of Substrate and Enzyme on a Reaction Rate Abstract In living organisms‚ certain reactions must take place rapidly to assist life. This occurs because of enzymes‚ because all reactions would take place too slowly to sustain life (Jacklet‚ 237). Enzymes are large protein molecules that catalyze specific chemical reactions without being used up in the process. Each enzyme has a region on its surface‚ called the active site‚ which recognizes a specific

with quadrants that contain the culture‚ a hemacytometer‚ was used to carry out this experiment. After the data was collected from using the hemacytometer‚ the results of the difference between the two cultures was to be determined through a t-test. As the test was conducted‚ the study shows that the difference between lacking an antibiotic and containing one is not different. An antibiotic in culture-A and culture-B does not affect the number of yielded yeast cells. Introduction. -- It is undetermined

I) Introduction In this lab‚ a test was conducted to determine how the relative redox activity of chloroplasts from spinach leaves‚ which were performing photosynthesis‚ would change when in the presence or absence of light. To observe these changes in redox activity‚ the chloroplasts were exposed to DCPIP‚ a chemical that changes color according to such activity. By determining the redox activity of the chloroplasts‚ it could then be inferred which chloroplasts were photosynthesizing more actively

Title: Observation of Macroscopic Chemical Changes‚ Alice Kimbrell‚ Chemistry 101-DS01:74589‚ 5/31/2013. Purpose: In this lab‚ I will observe macroscopic changes that occur when mixing together certain chemicals and household cleaners. The mixing of the chemicals provided with each other and with acid/base indicators demonstrates how matter can change‚ and how chemistry can be seen with the naked eye. By mixing household cleaners with an acid/base indicator I hope to demonstrate how these

Kathleen Kramas Cells and Heredity Lab Tuesday 2:00-4:50 22 OCTOBER 2012 Membrane Permeability Decreases as Molecular Size Increases Introduction: Red blood cells are vital to organisms functioning properly. They are microscopic cells that carry oxygen from the lungs to all the tissues throughout the body. Upon transporting oxygen‚ red blood cells also exports waste‚ such as carbon dioxide‚ to the lungs where it can be expelled. Red blood cells are made up of hemoglobin which is surrounded by a

INTRODUCTION The Gram Negative lab had two parts; the aim of the first part is to determine the concentration of gram negative bacteria in a water sample collected from a creek near Providence Road‚ Strickling. Gram negative bacteria have a cytoplasmic membrane‚ a thin peptidoglycan layer‚ and an additional outer membrane composed of phospholipids and lipopolysaccharides. Because gram negative bacteria have a relatively thin cell wall when compared to gram positive organisms‚ they are consequently

When Chemicals React! Mr. Bell’s honors level chemistry class conducted an experiment during their lab demonstrations‚ this consisted of elements such as phosphorus and calcium chloride in their experiment. This along with another hydrogen based sunstance produced‚ what looked like a pinkish-looking substance inside of their flasks that were at their lab stations. Sophmore Kelly Caudel said‚ “ I actualley enjoy doing the experiments in this class‚ because it gives us a chance to get away from

Battle of the Sciences: Dental Vs. Biochemical Engineering Deciding what I want to do for the next 60 years of my life is a pretty big step‚ especially at the young age of eighteen. Making this decision involves choosing a school that is well suited for me‚ and picking a field to major in. Fortunately‚ I have half of the process figured out. I have chosen to attend Augustana University this upcoming fall (Go Vikings!)‚ but am still undecided as to what my major will be. I have always been fascinated
