The branch of biology dealing with interactions along organisms and between organisms and their environment is called Ecology, I believe.
Answer:
ATP production.
Explanation:
The result will be the production of ATP molecules if we place thylakoids in a beaker with a solution that mimics the chloroplast stroma in direct sunlight. The thylakoids are able to formed ATP in the dark because H+ gradient is required for ATP synthesis. The scientists find out that the light reactions were not necessary to establish the H+ gradient required for ATP synthesis by ATP synthase.
I think the correct answer would be C. It would be restricting water and/or nutrients, instead of supplying ample quantities of both that would not change the results of the experiment. This is because you are still supplying the same amount of nutrients and other things needed by the plant so the ratio of the growth of the plants will still be the same.
