Milam is doing an experiment on fish expansion life. So, he has two tanks: one with salt water and another with regular water. He placed five fish in each tank. He recorded the results within five weeks. Two fish died in salt water while a fish died in the regular water tank. Can someone please help me find the independent variable, the dependent variable, and the control variable?
