Question

Which experimental procedure would provide the best evidence for the effect of light on plant growth?

Options:
Plant seeds in different souls and expose them to different amounts of light, then measure plant growth
Plant seeds of the same variety in the same conditions and vary only the amount of light, then measure plant growth
Measure plants receiving different amounts of light in their natural environments
Measure plants of the same variety grown in environments that receive different amounts of light

The experimental procedure that would provide the best evidence for the effect of light on plant growth would be to plant seeds of the same variety in the same conditions and vary only the amount of light, then measure plant growth. This controlled experiment allows for the isolation of light as the independent variable, while keeping all other variables constant. By comparing the plant growth under different light conditions, the true effect of light on plant growth can be determined.

Answer 2

Which one out of my options

Answer 3

The second option, "Plant seeds of the same variety in the same conditions and vary only the amount of light, then measure plant growth," would provide the best evidence for the effect of light on plant growth. This experimental procedure allows for the specific examination of how different amounts of light affect plant growth, as all other variables are controlled.
