initial rate of reaction. I will measure the effect of the enzyme in 5 different concentrations against the controlled variable of the reactant. The enzyme which will be used is different concentrations of potato and the reactant used will be Hydrogen Peroxide. Hydrogen Peroxide which will be the buffer solution is a PH of 7.2. My hypothesis for the experiment is that as the concentration of the enzyme is increased the rate of reaction will be increased‚ producing oxygen at a faster rate. The results

exchange rate system. China has announced in 2005 the “end of its firm peg against the dollar‚ instead allowing it to trade within a narrow band against a basket of currencies.” China regime is managed floating system where the currency increases very slowly year by year and the China government prevent the currency from changing quickly in the short term. The reason why Chinese government intervene in the currency market is to lower exchange rate to increase employment‚ maintain a fixed rate to maintain

Activity One: 1. The two major variables that affect the rate of diffusion: a. The composition of the lipid bilayer (eg. more cholesterol‚ less permeability to polar substances) b. The structure of the molecule undergoing diffusion (eg. steric conformation‚ size‚ polarity‚ amount and strength of hydrogen bonding) 2. Urea was not able to diffuse through the 20 MWCO because the pores of the membrane were too small for the urea to pass through. The molecular weight of urea is 60.06 g/mol‚ over

Aerobic metabolism‚ uses fats‚ proteins and carbohydrates that are oxidized and turned into carbon dioxide and water. Anaerobic metabolism‚ uses only carbohydrates and enters the fluid‚ or cytoplasm‚ of the cell and is turned into lactic acid. Aerobic exercises are running‚ biking‚ and swimming‚ whereas anaerobic exercises are sprinting‚ jumping‚ weight training. 3. My activity is considered

Rising Divorce Rate Divorce rate is rising up year by year in Taiwan. According to Ministry of Interior’s research Taiwan’s divorce rate is the second highest of the world and it’s also the highest in Asia. There are some cause of divorce rate is rising and some effect it brings. First‚ according to Marital Crisis Management Association’s studies‚ a married person having extramarital relations is one of the reason cause a couple divorce. The effect it brings is distrust.

Science Coursework-Rates of Reactions Introduction Investigating how the concentration of sodium-thiosulphate (STS) and hydrochloric acid (HCL) affects the rate of reaction in the experiment. In addition I am also checking how different variables affect my experiment and also how I can make my test more precise‚ reliable and accurate. Strategy According to my results‚ as the concentration of STS solution increased the rate of reaction of my experiment was increased. Also as the concentration

Title: Erythrocyte Sedimentation Rate (ESR) Aim: To measure the erythrocyte sedimentation rate of a patient to see if there could be anything wrong. Introduction: The erythrocyte sedimentation rate (ESR) is the distance that the red blood cells sediment in a specific time interval. ESR is an easy‚ inexpensive and non-specific test that is used to help protect conditions associated with acute and chronic inflammation including infections‚ cancers and autoimmune diseases. ESR is said to be non-specific
