interesting investigation into the effects of different chemical concentrations on a metabolic process and whether or not an increase of caffeine would increase the rate of metabolism in multi-celled organisms. These daphnia have been kept in a freshwater habitat at room temperature beforehand. Hypothesis It is predicted that a higher concentration of caffeine the daphnia are subjected to will increase the heart rate more than compared to a solution of a lower caffeine concentration.
