Q
- What is the dependent variable in this experiment?
An experiment was designed to investigate the effect of caffeine on the heartbreak of water fleas. Two populations of water fleas were cultured. Both populations had water with the same mineral content, were supplied with identical amount of bacteria as food, received the same amount of light, and had their temperature maintained at 20C. Every two hours, water fleas from both populations were selected and their heartbeats were monitored. The fleas of population A had caffeine administered five minutes before their heartbeat was checked. The fleas of population B were given nothing.
A
The heartbeat of water fleas.
