Osmosis Lab Problem: What’s the order of the concentration for each solution and how does it affect the movement of water? Hypothesis: Experimenter thinks the order of the solutions according to their concentration is D‚A‚E‚C‚B‚ from smallest. And the water will pass through semipermeable tubing bag from low to high concentration to thin the concentration inside the bag. Osmosis is a diffusion of water particles and is one of the passive transport that the molecules try to reach equilibrium is

cheese. Lactic acid bacteria(LAB)‚ a bacteria that can be found in the production of cheese‚ its stress gene was investigated in the experiment by using various biochemical and genetic techniques to identify and extract. The characterisation of the strain illustrates how identification of strains differ using different methods‚ such as gram stain and 16s rRNA screening. After the characterisation‚ the stress gene isolation assist the further understanding of the gene on LAB be giving different stress

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

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

indicated by a very pale pink color. To calculate the molarity of NaOH‚ the following equation was used MNaOH x VNaOH = MKHP x VKHP therefore the molarity was .125 M. INTRODUCTION This lab experiment covers the preparation of standard solution and the acid/base titration. The first part of the lab is to prepare a standard solution of Potassium hydrogen per. A standard solution is a solution of known concentration‚ in which it is prepared using exacting techniques to make sure that the molarity

The 7 Deadly Sins and 7 Cardinal Virtues ======================================== Overview -------- The "Seven Deadly Sins"’‚ also known as the "Capital Vices" or "Cardinal Sins"‚ are a classification of vices that were originally used in early Christian teachings to educate and instruct followers concerning (immoral) fallen man’s tendency to sin. The Roman Catholic Church divided sin into two principal categories: "venial"‚ which are relatively minor‚ and could be forgiven through any sacrament

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
