Question

identify three (3) constants for this experiment.
a pet store owner wants to see what will happen if they feed tanks of goldfish different amounts of food. one tank of goldfish is fed the normal amount which is once a day, a second tank is fed twice a day, and a third tank is fed four times a day during a six - week study. the fishes’ body fat is recorded daily.

Explanation:

To identify constants in the experiment, we analyze factors kept unchanged. The type of fish (goldfish), the duration of the study (six - week), and the environment of the tanks (assuming same tank conditions like water quality, tank size) are constants. The independent variable is the feeding frequency/amount, and the dependent is fish body fat. So constants are aspects not manipulated, like fish species, study duration, tank environment.

Answer:

Constants could be: the type of fish (goldfish), the duration of the study (six weeks), and the non - feeding - related tank conditions (e.g., water quality, tank size).
