Students are conducting an experiment in which they observe the heart rate of Daphnia, which are tiny water fleas. They place one group of Daphnia in water that has been cooled to 50°F. Another group of Daphnia is placed in water that is at room temperature, 70°F. A third group of Daphnia is placed in water that has been warmed to 90°F. After 10 minutes in the water, several individual Daphnia are removed and their heart rate is calculated and recorded in beats per minute. Based on the details of the experiment, which of the following scientific questions is being investigated by the students? Read a lengthy question 3 times

A. At what temperature do Daphnia best reproduce? B. How long can Daphnia survive in water that has been warmed to 90°F? C. What effect does cold temperature have on Daphnia metabolism? D. How does temperature affect the heart rate of Daphnia? S.IP.05.11
