Effect of Temperature on Peroxidase Ability to Break Down H2O2 By: Rodneika Crutcher Abstract Temperature affects the ability of peroxidase to break down hydrogen peroxide. In this experiment our professor extracted peroxidase from potato tissue. In order to determine how temperature affects peroxidase we created solutions and measured their absorbance levels after water bath treatments. The more absorbent the solution was the less hydrogen peroxide there was in the solution. This means the peroxidase

sulphuric acid which reduces the pH of water. The result of these reactions is increase in the solubility of heavy metals and consequently pollution of water resources. The Sarcheshmeh copper mine is one of the largest porphyry copper mines in the world which is located in south-eastern Iran. Chemical analysis of over than 600 water samples taken from streams and springs in the mining region and surrounding area of pit showed extensive changes in water quality and composition due to the passage of water

From this experiment I learnt that the bigger the size of the jelly is the more time its going to take for the colour change to take place‚ the colour change represents the rate of diffusion‚ the smaller the block of jelly is the less time its going to take for the colour change to take place which means the rate of diffusion

Draft 2 The political change that occurred during the French Revolution was based on the political philosophies of the 18th Century Age of Reason. The French Revolution hoped to use reason and natural law to reform the French government because of its inability to serve the needs of the nation. However‚ evident by the dramatic change in the revolution‚ the political philosophies used were not consistent throughout the period of 1776 to 1815. The beginning stages of the French Revolution were characterized

An experiment to investigate the factors which affect Resistance in a wire What is resistance? A potential difference (V) applied across a wire of length (l)‚ there is in the conductor‚ an electric field (E). In this electric field the free electrons are not however under continuous acceleration (Ee/m). This is because they repeatedly collide with the moderately massive vibrating atoms losing their kinetic energy. The vibrating atoms having gained this kinetic energy now vibrate more. The resulting
