Question

refer to the scenario. a scientist sets up an experiment to see how colored lights affect the height of plant growth. he grows one group of plants in full sunlight, one group under red lights, one group under blue lights, and one group under green lights. all the plants are exactly that same type and all receive an equal intensity (brightness) of light. at the end of the experiment he measures all the plants. what is the independent variable? sunlight the height of the plant the color of the light the intensity of the light

Explanation:

In an experiment, the independent variable is the factor that the scientist changes or manipulates. Here, the scientist is changing the color of the light (sunlight, red, blue, green) to see its effect on plant height. The height of the plant is the dependent variable as it depends on the color of the light. The intensity of light is kept constant.

Answer:

C. the color of the light
