The effect of varying temperature on thee Rennin enzyme Abstract The purpose of this experiment was to see what affect different temperate had on the reaction rate of the enzyme rennin. The experiment was performed by placing test tubes filled with renin and milk into water bath which was heated or cooled to one of the temperatures trialed. The hypothesis justified because it found because it though data that the enzyme reacted faster with the 45° temperate because it was

Mrs. Lovejoy English J075 Essay #3 I would not be the kind of person who takes orders blindly whether it is from an authority figure or not. I personally would not like to be on the opposite end of this situation therefore I would find myself resisting the orders to end another’s life. Sometimes you don’t have the necessary amount of time to decide whether or not what you are being asked to do is the right thing or not‚ and in those kinds of situations people normally find themselves making

Part I - Illumination Experiments (1924-27) These experiments were performed to find out the effect of different levels of illumination (lighting) on productivity of labour. The brightness of the light was increased and decreased to find out the effect on the productivity of the test group. Surprisingly‚ the productivity increased even when the level of illumination was decreased. It was concluded that factors other than light were also important.

so deeply ingrained and powerful that it cancels out a person’s ability to behave morally‚ ethically‚ or even sympathetically. In 1963 Milgram carried out an experiment. He hypothesized that individuals who would never intentionally cause someone physical harm would do so if ordered by a powerful authority figure. To carry out the experiment‚ Milgram designed a shock generator- a large electronic device with 30 switches labeled with voltage levels from 30 volts increasing at 15-volt intervals to
