Help with marine science questions!?

Kara, I have noticed that you keep posting your entire homework ignment/exam questions. The fact that you are not trying these problems out on your own and are using this website as a means to cheat the system is really only cheating you. You will find that this may make people less willing to help you out. Try these problems yourself and if you are stuck on one or two, then post it with your guess and why you think that is the answer, then we may be more willing to help.
