lol so theres like a flood of questions, you guys can come here and we'll try to figure them out together till the key is posted!

my first question is: for the diagram of the cell membrane, did you guys get B as the thing that receives the chemical signals?

feel free to post your own questions!
:)
for dolly, i got the one that said the dna was identical to sheep A, cause thats where the nucleus came from
also, what did everyone write for the introduction of foreign species
 
I forget about the chemical signals



For the dichotomous key it was something that had to make sence. I put:

1a: Has legs.....go to 2
1.b No legs......go to 3
2a Four legs....... (organism # here) (dog)
2b 8 legs.............(organism #) (spider)
3b. Has fins..............(organism #) (fish)
3b No fins..........(#)(earthworm)
