Allison and Heather are going to conduct an experiment to see whether salt affects the growth of plants. They gather five groups of identical plants and give the plants in each group water with a different salt concentration. What is the outcome variable (dependent variable) for their experiment?

The dependant variable is the growth of the plants.

Explanation:

The independent variable is what changes the dependent variable.

for example, the type of salt concentration ( Independent variable ) is/ isn't going to change the growth ( dependant variable ) of the plant.

genetic variation will increase because of a new habitat and food source.

explanation:

the answer would be   10%
