Answer:
Variables that cannot be associated with its population dynamics, in this case, for example, different streams with the same characteristics (for example, orientation, force direction, etc).
Explanation:
In this experiment, examples of dependent variables may include the growth rate, the survival rate, and the birth values of freshwater mussels.
The dependent variables are those you have to measure exactly in the experiment. In this case, dependent variables are represented by population values of freshwater mussels under different stream conditions.
The correct answer is letter A. The disk soaked in distilled water is the controlled variable because it is the only differential factor from all of the other variables which are all disinfectants. Controlled variables are elements that are not changed throughout the experiment. When something is unchanged it is better for scientists to analyze the relationships of other variables better.
