Laboratory Report The Plasma Membrane I. Introduction The Plasma membrane is the edge of life‚ the boundary that separates the cell from its surroundings. It controls the traffic of materials in and out of the cell. (Reece‚ 2011). It is incredibly thin that is very vital in maintaining the integrity of the cell. Not only does the plasma membrane bind the other organelles‚ it also forms a dynamic structure which gives them their remarkable activity and selectivity. (Hickman‚ 2008). Diffusion

growth was for water treated B.pumilus and the lowest mean root growth was the salt water treated control. Water treated V.paradoxus has a higher mean root growth compared with salt water‚ with a high margin of error. B.pumilus has the largest difference between root growth between water treated and salt water treated. (Table 1) Table 1: Individual results of Brassica mean root growth (mm). These were treated with Bacillus pumilus and Variovorax paradoxus under water and salt water (100mM‚ NaCl)

Lab Report – Strong Example Problem/Question Does using a base coat before painting nails prevent chipping? Background Information When painting nails‚ some manicurists use a base coat before applying the polish. The purpose of a base coat is to help the polish stick to your nails more easily. Base coats also help to protect your natural nail from the staining effects of colored polishes. Ridge-filling base coats fill in the grooves and cracks in the nail to create a smoother appearance

of positive and negative charges that are useful in order to conduct energy. Simultaneously‚ we have also found out that saltwater conducts energy because of the solid salt it contains and when it is dissolved into water‚ the elements sodium and chloride from the salt separate or break up because of the very reactive traits of water (H2O)‚ thus‚ causing the production of positive and negative ions that are able to carry energy and consequently conducting electricity. The particular

Organic Chemistry II Lab 9 Fermentation of a Carbohydrate: Ethanol from Sucrose * Introduction Ethanol is one of the oldest alcohols and also the least toxic one. Industrially‚ ethanol is made most economically by hydration of ethylene. However‚ ethanol that is intended for human consumption must‚ by law‚ be prepared by fermentation. By either method‚ ethanol‚ of course‚ has the same formula‚ structure‚ and properties. The fermentation takes place with the assistance of enzymes from yeast

Experiment 4: Qualitative Analysis of Cations and Precipitation Reactions The overall goal of experiment four was to determine the identity of unknown cations presented to the student. But in order to know the identity of these unknowns‚ in part 1‚ Ag+‚ Pb+‚ and Hg22+ were presented to the student in aqueous solutions and then precipitated through experimentation. In part 2‚ the same procedure was enacted to determine which substances precipitated through qualitative analysis. Solubility rules

Lab Report: Toothpickase and Enzymes September 19‚ 2012 Olivia DePhillips Lab Partner: Joy Morgan Meyers Signature: Introduction Enzymes are biological molecules that catalyze chemical reactions. In enzymatic reactions‚ the molecules at the beginning of the process‚ called substrates‚ are converted into different molecules‚ called products. Almost all chemical reactions in a biological cell need enzymes in order to occur at rates sufficient for life. Like all catalysts‚ enzymes work
