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

SLIDE A slide show is a es of still images on a projection screen or electronic display device‚ typically in a prearranged sequence. Each image is usually displayed for at least a few seconds‚ and sometimes for several minutes‚ before it is replaced by the next image. The changes may be automatic and at regular intervals or they may be manually controlled by a presenter or the viewer.
