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 independent

a. will be the wavelength of the light
b. will be the plant on which the light is shining
c. will be the rate of photosynthesis
d. cannot be determined

The correct answer is A. will be the wavelength of the light

Explanation:

In an experiment, there are two main variables: the independent variable and the dependent variable. In the case of the independent variable, this refers to the factor or element that is manipulated on purpose to understand the relation of the independent variable with the main phenomenon being studied (dependent variable).

This implies, in the experiment presented the independent variable will be the wavelength of the light because this is the factor or variable that is being manipulated. On the other hand, the dependent variable would be the rate of photosynthesis because this is the element studied that is affected by the independent variable.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
