This is а multipаrt prоblem. Answer eаch part (A-B) in the individual spaces prоvided. Belоw is an experimental setup for measuring the rate of photosynthesis using the aquatic plant Elodea. (A.) (1 point) Why does the solution level move to the right when the light is turned on? Type only a capital letter for the correct choice in the space provided. A. The Elodea produced CO2 gas which increased the volume in the test tube. B. The Elodea grew rapidly which increased the volume in the test tube. C. The water in the test tube heated up and expanded, increasing the volume in the test tube. D. The Elodea produced O2 gas which increased the volume in the test tube E. None of these Answer to Part A: Choice Letter [BLANK-1] (B.) (1 point) In one of the experiments, green dye was used to tint the water in the beaker green. Why did this reduce the rate of photosynthesis? Type only a capital letter for the correct choice in the space provided. A. Green plants absorb the energy from green light but cannot use green light to drive photosynthesis. B. The green dye filtered out the wavelengths of light used by green plants to drive photosynthesis. C. The green dye filtered out all the wavelengths of light, leaving no light to be transmitted to the plant. D. The question has a false premise, because the rate of photosynthesis by Elodea was not affected by the green dye. E. None of these Answer to Part B: Choice Letter [BLANK-2]
