You place two fish in different sized tanks, after a month, you measure the length of the fish. What is the manipulated variable and the responding variable?

The manipulated variable is how many fish you put in the tank. The responding variable is how much the fish have grown.

Explanation:

A manipulative variable is the independent variable in an experiment or equation. It's called “manipulated” because it's the one you can change in the problem. A responding variable is something that “responds” to changes you make in an experiment. Hope this helps!

not the best question format lol but what i think might as scale color is controlled by a single gene with two alleles, the green allele and the yellow allele. when moths that are homozygous for green scales are mated with moths that are homozygous for yellow scales, 100% of the offspring have green scales.
