Published: Mon, 5 Dec In this experiment, I am going to determine the effect of different concentration of caffeine on the heart rate of Daphnia.
Daphnia is assumed as the substitute of human being in this experiment to investigate the effect of chemicals on the heart beat of living organisms. Thus, when they are inhibited by caffeine, the stimulatory signal remains active for a longer period of time resulting in a greater sense of alertness (a CNS effect) but .
