Kidneys couldn't work without the couldn't leave the body

Kidneys couldn't work without the urinary tract because waste couldn't leave the body.

Explanation:

Kidneys have an important function: to filter out waste or toxins. Each kidney is attached to a ureter, which is tube that propel urine from the kidney to the urinary bladder. That's why the statement should be this way: ''Kidneys couldn't work without the urinary tract because waste couldn't leave the body''.

Yeah, the answer is definitely b.assuming that you're a high school student or middle school student, you probably don't need your parents' to pick out your clothes anymore. and i don't know how it works at other schools, but i know that at my high school, you don't get to pick the book you read for an english assignment. your teacher picks that. the decision of what after-school job i should get, i would definitely make with from my parents and other people that i trust. ultimately, the decision is up to me, but i would need advice from people who are more experienced.

That’s what i was going to say.
