A friend оf yоurs wаnts tо cаrry out аn experiment to test how well plants grow under specific wavelengths of light. They propose setting up an experiment where they grow plants for several months under the following conditions: red light blue light red and blue light They propose using no light (darkness) as a control. They tell you that a control has to test the absence of the variable of interest, so they need to compare plant growth in the dark with plant growth under the three light conditions they propose. What is wrong with using no light (darkness) as a control for this experiment? Briefly explain your reasoning. What would be a more appropriate control to use to tell what the impact of specific wavelengths was on plant growth? Briefly explain your reasoning.
