An experiment was designed to investigate the effect of caffeine on the heartbeat of water fleas. Two populations of water fleas were cultured. Both populations had water with the same mineral content, were supplied with identical amounts of bacteria as food, recieved the same amount of light, and had their temperature maintained at 20 degrees Celsius. Every two hours, water fleas from both populations were selected and their heartbeats monitored. The fleas in population one had caffeine administered five minutes before the heartbeat was measured. The fleas in population two were given nothing. Which is the independent variable?

• water temperature

• heartbeat

• caffeine

• population 2
