    LOL anyone put how the dialysis thing can selectively reabsorb???? (this is the 1marker about whats different between the 2 or something)
    I put that the dialysis membrane acts a as a partially permeable membrane, so larger molecules cant get across or something so hopefully it's something along those lines.

    definitely not just "membrane". Inner membrane for sure
    mark scheme will say
    (inner) membrane

    3 marker on auto and heterotrophs anyone? i basically did the 2 defentitions etc to fit the question and then just how they need organic mols like glucose for respiration, muscle contraction etc, anyone?
    i put plants produce oxygen for aerobic respiration

    Would I get a mark if I write negative feedback for the first one and positive for the second?
    You wouldn't get marks for naming what feedback mechanism they were.

    I put autotrophs can produce carbohydrates whilst heterotrophs cannot, therefore heterotrophs need to eat and digest these substances to get amino acids and glucose for energy etc.

    but it was specifically pointing to the inner membrane, because it was 3d?

    I doubt it. It pointed specifically at inner membrane.

    It said how heterotrophs rely on plants, so I think you should have said that plants produce Oxygen from photosynthesis, which heterotrophs need for aerobic respiration.

    And talk about how heterotrophs release the chemical potential energy stored in the complex, organic molecules for biological processes.

    doesn't sensory and motor neurone connect to the relay neurone? hence two synapses?

    Yeah that's right. Just mentioning limiting factors won't get you the mark.
    How many marks was this question? Completely left out the Calvin cycle stuff, just spoke about limiting factors, think it would get me one?

    Why is everyone so sure about CO2 conc being the limiting factor, surely Temperature could also be a limiting factor?
    Yes it could, I doubt you'll be penalised either way.
