Hi,
This your question is incomplete but i think it should read as;
William is testing what type of light best helps bean plants grow. He plants four beans in four separate pots. He places each pot in a different room and subjects them to different types of light, and he waters each plant the same amount. He uses sunlight, ultraviolet, fluorescent, and black light. William then measures the height and growth rate of each plant. What is the control for William’s experiment?
So the answer is sunlight.
You should appreciate the fact that variable is the type of light used, and the control is used to measure the effects of the variables, so since sunlight is the normal light, it is the control.
It is A, daylight.
The variable is the sort of light utilized, and the control is utilized to gauge the impacts of the factors, so since daylight is the ordinary light, it is the control.
Daylight introduction in the late spring can prepare your body to stock up on nutrient D3 that can last all through the fall and yield for the generation of more nutrient D, which prompts higher serotonin levels.
Skin that is presented to bright (UV) beams discharge a compound, nitric oxide, which brings down circulatory strain.
