Question

Which is the best hypothesis for the scientific question "how does light intensity affect the rate of photosynthesis"?A) light intensity, co2 concentration, and temperature are factors that determine the rate of photosynthesis.B) light intensity has no effect on the rate of photosynthesis.C) if the distance between the source of light and the plant is increased, the rate of photosynthesis will decrease.D) light intensity has an impact on the rate of photosynthesis.

Answer 1

Answer:

D

Explanation:

A hypothesis is based on assumptions. Assumptions, on the other hand, are developed from the limited evidence available. In this case, it can be rightly assumed that light intensity has an impact on photosynthesis based on what is observed in the environment. However, to prove or disapprove the hypothesis, controlled experiments need to be conducted.

A good hypothesis is also simple and clear.
