Question

8. Nathan was planning an experiment to test if plants could live in an environment with high oxygen concentration. What are some possible questions Nathan could ask regarding his control set-up for the experiment?​

Answer 1

Answer:

The big issue Nathan is going to have is CO2 levels. He needs to control for those in his experiment. Since CO2 is such a trace gas displacing CO2 or having photosynthesis take it away is very serious as a problem. He needs to control since CO2 is so trace level because lowering it by 1/2 can kill his plants and he would think that the plants were dying from Oxygen.
