I couldn't help noticing that you posted your whole homework here. Try giving your answers and then someone might help you understand where you are wrong and tell you where you are right.

Would you rather be poked by a needle or pee on a stick if given the choice between the two?
A urine dipstick test is a non-invasive procedure....pure and simple.
