Question

IV - amount of water
DV - Rate of photosynthesis
What’s the hypothesis

Answer 1

Answer:

$H_{0}$: The amount of water will have no effect on the rate of photosynthesis.

$H_{1}$: A larger amount of water will increase the rate of photosynthesis.

$H_{0}$ means null hypothesis, a hypothesis where the independent variable, in this case, the amount of water, has no effect on the dependent variable.
