James took two pea plants one in a dark closet and the other in a sunny window sill. both are located in air conditioned rooms. he then measured the growth of the pea plants after a week in thea experiment, sunlight is a(n)

I would believe sunlight to be an independent variable as the sunlight is the control of the whole experiment. You can tell because he placed one in a dark area and the other in a sunny area.

The dependent variable would be: Growth

Controls: The air-conditioning in both rooms

It is not constant because this would be the variable that would remain the same, for example, the type of plant was kept the same.

Hope this helps c:

C. definite shape, definite volume. that is a solid.
