    CFCs are greenhouse gases, along with: water vapour, carbon dioxide, methane, and nitrous oxides.
    I meant because I thought I remembered it saying name another, which made me think since CFCs is really a category rather than one gas, it wouldn't be accepted.

    It'd be pretty harsh if they didn't accept CFCs. I'm almost certain you'll get the mark.

    You get 0.75 if you do 90/120.. I don't know which one is right because I don't know if you have to convert it to metres or not.
    of course it is 0.0075 why won't you convert it to metres?

    I can't quite remember what the protective eye question was but was it sclera or conjunctiva, or both?

    The conjuctiva doesn't really protect the eye, it lubricates it. I put sclera, but technically it could also be the cornea.

    I put that he will transport more oxygen every breath because he uses anaerobic respiration so to avoid the heart having to beat constantly and quickly which may cause the arteries to be blocked, it beats less frequently but with more force to deliver more oxygen every time. Thus, lower heart rate..
    Anyone agree?

    I put conjunctiva, what does the sclera protect the eye from? the conjunctiva makes more sense.

    Also is sulfur dioxide not a greenhouse gas? That's what I put

    Snail one I talked about how mutation caused lighter snail shell allele which acted as camouflage against the secondary consumer in the previous question, so these passed on their alleles to their children and the black snails became extinct
