Read the paragraph below. What is the dependent variable?

Dr. Weingaertner wants to know if water temperature affects the growth rate of guppies. She sets up an experiment with two aquariums. Aquarium #1 has 100 guppies and in kept at 73 degrees Fahrenheit while aquarium #2 also has 100 guppies and is kept at 80 degrees Fahrenheit. Both aquariums have the same amount of water, receive the same amount of light and have the same gravel bottom. All the guppies are fed the same amount of food at the same time of day.

• the water temperature

• the growth rate of guppies

• the amount of food given

• all of these
