Question

a student wants to design an experiment to test the hypothesis \temperature affects the reproductive rate of bacteria\. what should the independent variable be? image of various bacteria the temperature of the environment the type of bacteria used the culture medium of the bacteria the reproductive rate of the bacteria a student is testing to see the effect of light on the growth of a bean plant. she places one plant in sunlight and the other plant in a darkened

Explanation:

In an experiment, the independent variable is the factor that is manipulated to observe its effect on the dependent variable. The hypothesis here is that temperature affects the reproductive rate of bacteria. So we manipulate temperature (the independent variable) to see how it affects the reproductive rate (dependent variable). The type of bacteria and culture medium should be controlled (constant), and reproductive rate is the dependent variable. So the independent variable is the temperature of the environment.

Answer:

the temperature of the environment
