Daphnia’s heart rate will increase. If we add cold water‚ the Daphnia’s heart rate will decrease. If we add epinephrine‚ then the heart rate will increase. MATERIALS AND METHODS A pipet was used to place the Daphnia with water on a glass slide. The slide was then placed under a glass microscope to be observed for the experiment. A tally counter was used to count the heart rates of the Daphnia when it was placed in warm water‚ under ice and in epinephrine. RESULTS When we experimented what the
