Answer 2

Answer:

Your experimental variable is MOLD

Explanation:

You want to know what happened to mold if it's grown or not.

That's the variable you can't control and it's what you want to study.

The bread is a non-variable, you put some amount and that's it.

The sun is a variable but you control it, regardless of the "amount" of sun you use, but it's only about if there is or not the process of sun.
