Biology help?
Do your own homework- that is what school is for. I can understand posting some questions that you are having difficulty with, but this is just pure laziness. Put down the video game controller, and do your own homework. I don't have a problem helping people with concepts they have difficulty understanding, but you haven't even made an effort here.
Reply:That's totally going to get someone to help you.
I doubt it was really 18 out of 100 of your questions...
This just looks to me like you forgot to do your homework.
Good luck on your next test. Report It
