Answer 5

I knew that...but I'm not sure how that relates to this problem. I"m not seeing how the kidneys will affect the excretory system.

Answer 6

Well, it says the kidneys prevents the buildup of wastes and extra fluid in the body..so if it weakened it wouldn't prevent it as much.

Answer 7

so there would be more fluid in the body that wouldn't pass through?

Answer 8

Yes.

Answer 9

so the answer would be D. right?

Answer 10

Yeah, I think that's right..but C also does..but D sounds like the best choice..
