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

That’d be C. The rate of photosynthesis is dependent on the wavelength of the light(independent variable).

Answer 2

Answer:

will be the rate of photosynthesis

Explanation:

A dependent variable in an experiment is the process or factor that is altered or affected by a related factor called the independent variable. In the given experiment, effect of wavelength of light is observed on the rate of photosynthesis in plants.  

Here, the rate of photosynthesis is supposed to be changed when the experimental plant is exposed to various wavelengths of light. This makes the "rate of photosynthesis" dependent variable for the experiment as it is affected by the "wavelengths of the light" to which it is exposed.
