Using the razor blade cut all the cylinders to a uniform length approximately 4.5 cm long‚ making sure to remove the skin from the ends in the process. 4. Place all the cylinders into a Petri dish and cover to prevent drying out. 5. Remove a cylinder and cut into discs about 5mm thick using the razor blade. 6. Remove excess water from the discs by blotting

The aim of this experiment was to investigate the effect that a glucose concentration has on the rate of fermentation. This was done by adding a variety of different glucose concentration into a test tube‚ siting in a water bath. The carbon dioxide would be collected in the test tube and therefore would measure the rate of fermentation. The results parsley supported the hypothesis that‚ “If the glucose concentration increases‚ the rate of fermentation increases‚ therefore the more carbon dioxide

Introduction Eutrophication is an increase in the amount of plant nutrients in a body of water(Ford-2000). A Eutorhication process that takes a long period of time to occur. It involves the transformation of a new lake and an old one. Because it has clear water and low nutrient content the young lake is called oligotrophic‚ and the older lake is different in that it is murky water and has a high level of nutrient‚ which is called atrophic. This process is natural and since it is it takes a long
