In the fermentation experiment using yeast with the different sugars what was the dependent variable

The dependent variable is fermentation rate.

Explanation:

When finding dependent variable phrase it like this:

depends on .

Where the first blank is the dependent variable and the second blank is the independent variable. For example, if I were to test the effects of pH on an enzyme, I would say the function of the enzyme depends on the pH level. This makes the function of the enzyme the dependent variable. In this case, fermentation rate depends on the different sugars. Hope this helps!
