To set up this experiment‚ two twenty-five gallon aquariums‚ 3 petri-dishes‚ 200 flies‚ rotten bananas‚ and yeast were used. It was decided that there would be 80 vestigial flies and 20 wild type flies to total to an initial population of 100 drosophila. In the sexual selection circumstance‚ the vestigial drosophila’s carrying capacity is somewhere around 80

BIO 211 Lab Section 11 February 15‚ 2012 Effects of Temperature on Enzymatic Activity Abstract Temperature is a measure of kinetic energy. As this movement increases‚ collision rate and intensity‚ and therefore reaction rates‚ increase. This experiment was conducted to determine if there is a minimum temperature that increase kinetic energy and denature enzymes to slow enzymatic reactions or fail to catalyze them. The experimental results indicate an increase in temperature will increase reaction

Introduction It is believed that many Christians or even atheists are familiar with the final meal that Jesus shared with his Apostles in Jerusalem before his crucifixion. They would refer to it as The Last Supper. It is one of the most important events recorded in bible which is appeared in Synoptic Gospels .
