Answer 1

The scientist's scientific question is:

Does the amount of nitrogen affect the number of flowers on a plant?

This is because the only variable being manipulated in the experiment is the type of water used (regular vs. nitrogen-enriched), which aims to observe its effect on the number of flowers produced by each plant.
