Question: What

Answer 1

Answer:

Hi there!

Your answer is:

Dependent variable: Plant growth

Independent variable: Day length

Explanation:

The independent variable is Intentionally manipulated by the researchers. We know exactly what it will be each day, because we control it! Since the scientists are controlling the day length, that is your independent variable.

The dependent variable is NOT manipulated by the researchers. We are studying what the dependent variable does in reaction to the changing independent variable. Since we are recording & studying how the plant grows based on the day length, that is your dependent variable!

I hope this helps!
