Final answer:
The research question is how pH levels affect the production of glucose. The hypothesis can be stated as 'If the pH level of the environment is acidic, then the production of glucose will decrease.' The independent variable is the pH level of the environment, and the dependent variable is the production of glucose.
Step-by-step explanation:
The research question is: How would pH levels affect the production of glucose?
The hypothesis could be: If the pH level of the environment is acidic, then the production of glucose will decrease.
The independent variable in this research question is the pH level of the environment.
The dependent variable is the production of glucose.
The control in this experiment would be maintaining a constant temperature and light intensity, as those factors could also affect the production of glucose.
