AndrewGuerrero BIO 125 Lab Due November 14‚ 2012 Practical Exam 1. a. The symbionts (Paramecium) of the termite belong to the kingdom Protista b. Paramecium living in the intestines of termites breaks down the cellulose walls of wood fibers releasing proteins that are absorbed by the termites’ digestive system. Paramecium benefit by having an environment to thrive and they ingest the wood fibers for their own nutrition as well. 2. c. An important ecological effect

Crystallization: Lab Report Theory/Introduction The purpose of this lab is to understand the concept of purification through crystallization. Crystallization is the process of purifying a substance‚ with the most adequate solvent. The process of crystallization came to be based on the principle of solubility. First‚ we must choose a solvent. The solvent is crucial to crystallization because it’s what will allow impurities to dissolve. Therefore‚ when selecting a solvent it is important that it

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

Abstract: The Enzyme Lab results where when the liver was frozen‚ its reaction was fast‚ and when it was hot‚ it was slow‚ and the liver that was at room temperature reacted slowly to medium. Introduction: The Enzyme Lab is to conduct investigations to determine the most favorable conditions for the most efficient enzyme activity. Variables to be used testing include temperature‚ pH values and surface area. Enzymes are proteins that speed up the rate of chemical reactions‚ which would otherwise
