Switzerland has the highest standard of living‚ trumping Canada‚ Italy‚ Argentina‚ and India. Based on the analysis of the seven aggregate statistics (refer to Appendix “A”)‚ Switzerland leads the other nations by having the highest GDP per capita‚ lowest government debt and lowest tax revenue as a percentage of GDP‚ lowest unemployment rate‚ lowest inflation rate‚ highest life expectancy‚ and second highest average level of education. These impressive statistics indicate that the Swiss government

What are the general requirements for a fatigue crack to form and propagate? The general requirements for a fatigue crack to form and propagate are: The presence of a local plastic stress; The presence of a tension stress; The presence of a cyclic stress (repeated or fluctuating). Eliminating any one of the above three requirements will stop

Biology Coursework: Preliminary Work 8/12/2013 Intro I am going to investigate a factor that affects the rate of enzyme activity What are enzymes and how do they work? Enzymes are biological catalysts - catalysts are substances that increase the rate of chemical reactions without being used up. Enzymes are also proteins and thus have a specific shape. They are therefore specific in the reactions that they catalyse - one enzyme will react with molecules

September 20‚ 2010 EXPERIMENT Acids‚ Bases‚ and Neutrals Problem Are common house-hold products pHs balanced and neutral? Information pH measures how acidic or alkaline a solution is. Its concept was introduced in 1909 by biochemist Soren Sorensen. The scale ranges from 0-14. Solutions that range from 0 to 6 are considered to be Acidic. Solution that’s on the Acidic end of the scale is low in ph‚ high in hydrogen ion‚ and low in hydroxyl ions. An acid have a sour taste‚ reacts with metal‚ are

Reaction of Enzyme Amylase Research Question: How will changing the percentage of sodium chloride concentration affect the rate of reaction of enzyme amylase‚ measured using the absorbance of starch and iodine with a spectrophotometer. Introduction: Amylase is an enzyme that is involved in the human digestive process. Found in both the human pancreas and the human saliva‚ amylase breaks down starch into sugar so that large molecules can be easily digested1. Like all enzymes‚ amylase must be kept

Experiment 4 – Effect of Temperature on Enzyme Activity Aim To study the effects of temperature on the activity of amylase enzyme on starch solution. Introduction Enzymes are widely known as biological catalyst. Almost all cellular reactions are controlled and guarded by enzymes. Virtually every metabolic reaction which takes place within a living organisms are catalyzed by enzymes. Enzymes are complex three-dimensional globular proteins. Some of the enzymes are built up off proteins and
