Ok. Step by step.

1.) Open your biology book to the relevant chapter.
2.) Read the relevant chapter.
3.) When you see the answer to a question while reading the relevant chapter, write the answer in the appropriate question blank.
4.) For any questions that you still can't answer, there is Google. Wikipedia is actually also a good resource.
5.) Complete the assignment and hand it in.
6.) Pay attention and take notes in class in the future so that you won't have to freak out about simple review questions.

Seriously, it is not our fault that you might fail this class. It is yours and yours alone. If you need to pass this class, then stop being lazy and trying to get other people to do your work for you. Without any help whatsoever, and only using the resources available, you could probably complete this homework in half an hour. Instead, you transcribe it to a message board and then go off to do other stuff. That's pretty lame.

If you need to pass this class, then you need to put some effort into passing this class.

Now, harshness aside, if you do the homework on your own, yet find there are concepts that you just aren't getting, feel free to post about them. If you do this, be sure to post what it is that you don't get, what information you have found about it, and what about that information is confusing you. Show some effort like that, and I'm sure many of us will be happy to help.

But, no, we will not do your homework for you. :roll:
