can survive in extreme environments. Halobacteria are also useful by being a good organism to perform DNA transcription‚ translation‚ and transformation on (Kramer‚ 2006). There are two different types of Halobacteria that are being observed in this lab. The first is NRC-1‚ which is also called the wild type strain. Although the pigmentation of the Halobacteria is caused by the production of the membrane protein‚ bacteriorhodopsin‚ which is a red‚ the wild type strain is pink in color. This pink color

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

Enzymes Lab Report Inroduction In this lab we explore an enzymes activity and how it can be affected by changes to its environment. An enzyme is a protein and is a catalyst to chemical reactions. It helps accelerate reactions by lowering the activation energy‚ which is needed for reactions in cells to progress at a higher rate. Activation energy is the minimum amount of energy needed for a chemical reaction to occur‚ yielding products from a given set of reactants. (Unit 7: Enzymes lab) Products

The Effect of Concentration on Absorbance Background Information The purpose of the “Determining Solution ‘Concentration’ Using A Spectrophotometer” lab was to use a spectrophotometer to find the relationship of concentration and absorbance obeying the Beer-Lambert law‚ which states concentration and absorbance are directly related‚ to then further determine the concentration of three unknown solutions. With the assumption that the solutions obey the Beer-Lambert law it is predicted that as concentration

technique is: Number Moles Concentrated Solution = Number Moles Dilute Solution. An instrument called a spectrophotometer detects the amount of light that passes through the sample and the percent transmittance can be recorded from the meter. In the lab‚ multiple homogeneous solutions are made. There was not a way to determine the differences in concentrations‚ but the Spec 20 made it possible to measure the difference. The Beer-Lambert Law is a graph used to record

Schoffstall Introduction In a normal human being the heart correctly functions by the blood first entering through the right atrium from the superior and inferior vena cava. This blood flow continues through the right atrioventricular valve into the right ventricle. The right ventricle contracts forcing the pulmonary valve to open leading blood flow through the pulmonary

Name : Andi Nadya Amanda Period : 4 Grade : 11 Enzyme Lab Report Question How heats effect the length of reaction time of an enzyme? Hypothesis I think the heat will make the length of reaction time of an enzyme become slowly. Heat is one of a way to denature the substrate. It means the heat will break down the structure of substrate in order the reaction of enzymes that we activated into it become slowly. Method for Collecting Data First I will record the length of reaction time

The Desert Biome Natashia Granger Bio/101 The Desert The desert is a dry barren area of land; it is in the Southwestern United States or areas of extreme heat and dryness. Deserts characteristically receive less than ten inches of precipitation a year. About one fifth of Earth’s surface is desert. Desert can be hot or cold
Premium Desert Precipitation Rain
to John Muir‚ “In every walk with nature‚ one receives far more than he seeks.” Desert hikers explore a desert for things such as different species of animals‚ a new environment or even a vacation. Not only for the enjoyment‚ but some may go out for business references. Regardless of‚ they must fully prepare themselves in order to survive in a desert. Inexperienced desert hikers do not fully prepare. Because some desert hikers are inexperienced‚ many dangers await them such as‚ the scorching heat‚
