2 is definitely A. Because a trace fossil is a type of fossil that provides evidence of the activities of ancient organisms.

11 is definitely Saltwater Crocodile.

Look, people like Ms. Sue are here to help you, not give you all the answers to the quiz. Before you judge the way she's helping, maybe you should go back and get a life and learn. So in the end, Ms. Sue isn't stupid; you are.

YOU ARE CHEATING BECAUSE I HAVE THE SAME QUESTIONS ON ONE OF MY SCIENCE TESTS FOR 7TH GRADE SCIENCE. NOBODY SHOULD HELP YOU, YOU, YOU, NUMB SCULL CHEATER. THIS TEST IS FROM FLVSFT CONNECTIONS ACADEMY 7TH GRADE SCIENCE AND YOU ARE CHEATING!!! I AM REPORTING THIS TO THE PRINCIPAL OF MIDDLE SHCOOL!!!! YOU WAIT MISTER, YOU ARE IN BIG TROUBLE!!!!!!!!!

IceLady900, I don't see whats the big deal when you are also looking up the answers. How else would you get here. You make me sick. Looking up the answers and acting like everyone is cheating but you.
- 8th CCA Science - Gracelyn, Monday, October 26, 2015 at 11:45am
Icelady900, if you know that, than you're cheating. You probably came on here to see what the answers are or to tell the principal. I came on here for help and that's all. Some people see this site as a cheating site. I only use it for the intentions it was set for. I understand that this is cheating, but some people don't go to FLVSFT whatever it may be and some people may not have the same test as you. I may come across as mean, but I'm saying this the nicest way possible. Most teachers use the same curriculum, so it's common that this isn't a test for some students, rather a practice sheet or a homework assignment.
