by observing cellular respiration only when photosynthesis occurs

Answer 1

The correct response is:

by observing cellular respiration under the absence of light.

This method allows scientists to measure the amount of oxygen consumed during cellular respiration, as photosynthesis does not occur in the absence of light, enabling a clearer understanding of oxygen usage solely for respiration.
