I would love to help you with your homework, however I have 3 questions for you:

1. What will you learn if I answer your questions?

2. How are you planning to pay me for helping you? (money is acceptable)

3. Have you read: http://www.biology-online.org/forumrules.php
(pay special attention to: 2, 3 and "ammendments" section)?

I'll only charge 5 CAD. I've got you both beat. Though being from the internet I can't guarantee every answer to be right, but that's the risk you pay.

At the first he came with PLEASE (all-caps) and in the end he said that way. I am not sure he has the answer, just to show us the ego :P

So what was the point of posting? Was it quizz (strange title though)?

Or maybe you have doubts on your answers, so post them, and tell us which one are doubtful and we will help. And for free with that. But we do not do your homework for you. I am done with mine, and won't help you for free :twisted:
