Question

In an experiment, the hypothesis is If the wavelength of the light shining on a plant is shortened, the rate of photosynthesis is slowed down. If this experiment is performed, the dependent variable _____. will be the wavelength of the light will be the plant on which the light is shining will be the rate of photosynthesis cannot be determined

Answer 1

will be the rate of photosynthesis

Answer 2

Answer:

Option C, will be the rate of photosynthesis

Explanation:

A dependent variable is one whose effect or existence is affected by any kind of change in the  independent variable. An independent variable is not affected by any other factor with in an experiment.

Here in this case , the wavelength of light is an independent factor as it is being modulated during the experiment to study its impact on rate of photosynthesis. The variable “rate of photosynthesis” is affected by the variation in independent variable “wavelength of light”, hence “rate of photosynthesis” is a dependent variable .
