HELP! please help I need this answer asap I don't really know how the points work but I set the amount to 20.
james took two pea plants, placing one in a dark closet and the other on a sunny window sill both are located in air-conditioned rooms. he then measured the growth of the pea plants after a week. in this experiment, the dark closet is a(n)____
1. dependent variable
2. constant
3. control
4. independent variable
If I remember correctly, it's the Independent variable, since the amount of sunlight (determined by where the plant was placed) controls how much it grows, but I'm not 100% sure. I know for certain that it's not 2 or 3.
