  2. Yes, it does help. Remember that I'm not a biologist and I don't know all of these answers.
    1 and 2 are right. I lean to a different answer for 3 although one function certainly is to support the body. I just don't know if that is the main function. 4 and 5 are right; your answer for 6 certainly is true but what about moving limbs so mark me as being unsure about 6.
    I agree with 7 and 8; I don't agree with 9. Chocolate contains caffeine and if anything caffeine will speed up and not depress; certainly it is not a depressant.
    I agree with 10. I don't have the foggiest about 11 and 12.
