Question

Jorge has made a hypothesis that the more you feed him out the shinier it’s fur will be because the mouse will be healthier

What should be a control in an experiment testing this hypothesis

A. How shiny each mouse fur is
B. The amount of food he feeds each mouse
C. The kind of mouse used in the experiment
D. How Jorge presents his data in his lab report

Answer 1

I think the correct answer is B

Answer 2

Answer: Option B

Explanation: in this case, the independent variable is the amount of food for each mouse, and the dependent variable is how shiny is the mouse.

So the control should be how shiny is a mouse with a normal amount of food, so when he changes the amount of food of the other mouses, he can compare the fur of those mouses with the fur of the control one.

Then the only thing that needs to be controlled is the amount of food that the scientist feeds to each mouse, then the correct option is B
