This answer is from gooogle. I’m not copying, I’m giving credit

Explanation:

Projectile motion, also known as parabolic motion, consists in launching a body with a velocity that form an angle α with the horizontal. In the following figure, you can see a representation of the situation. This motion is characteristic of projectiles, moving objects being affected only by gravity.

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
