Introduction The aims of the lab session was to familiarize with the principles‚ operation and application of a light spectrophotometer. This report discusses an experiment to study the relationship of absorbance and concentration‚ the interaction of electromagnetic radiant energy(ERE) and matter which is an important aspect of the Beer-Lambert ’s Law. This law states that the absorption of a compound is directly proportional to the concentration of that particular compound. This is because (a &

different possibilities of side effects. Antibiotics work by finding something in the pathogen that is different in the host cell and attacks it to stop the pathogen from reproducing and causing more harm. The side effects can range from loss of hearing all the way to discoloration of the teeth. Some may take these drugs and have no side effects at all except to obtain better health. While others may no receive any good from the medication and have horrible side effects. The mode of action also has

The effect of osmosis on artificial cells with different concentrations of sucrose Alex McRae Biology 120-902 Grand Valley State University 1 Campus Drive Allendale‚ MI 49401 mcraeal@mail.gvsu.edu Abstract In this study‚ we tested the validity of osmosis in artificial animal cells. Osmosis is the diffusion of free water across a membrane. The purpose of the study was to calculate the rate of osmosis in artificial cells containing different

Experimental Laboratory Report: An investigation into the rate of osmosis Liana Gohery - 98332250 12/12/2014 Word count - ………3000……….. 1. Abstract This study was conducted to investigate the effect of concentration gradients on the rate of osmosis. Osmosis is the cellular transport of water‚ this study was conducted to show the significance of the rate at which this occurs. Dialysis bags were filled with three different concentrations of sucrose solutions and two with water. They were

To whom it may concern‚ It has come to my attention that Liam‚ a young man of 23‚ had recently been diagnosed with severe liver damage. The disease had developed from 10 years of heavy drinking and as Liam was so young the disease was obviously more susceptible. After many advanced treatments being used on him‚ the only chance of saving Liam’s life was through a liver transplant‚ but sadly Liam was refused the transplant. Liam had begun drinking

Enzyme lab report. Introduction. An enzyme is a protein molecule that speeds up the rates of chemical reactions by many folds. They recognize‚ bind‚ and change specific reactants. They do not change thus can catalyze the same reaction again and again. Activation energy also known as an energy barrier is the amount of energy needed in order to begin a chemical reaction. Catecholase catalyzes the reaction rate of catechol oxidation. Catechol is found beneath the skin of many plants such
