    i get this

    but epo causes this in BONE marrow cells. not just any old cells. is the process the same? maybe im just looking into it too much

    yes. because the hormone goes into blood stream , and it only binds to cells which have the EPO receptors.
    its like when adrenaline is released into blood , but only binds to the SAN node in the heard becases thats where the receptors are.

    I did this in my mock and I got my 5 marks i thought my teacher was linient with me though

    Ecoptic beat causes the Q-R-S wave to be reversed inverted

    The ventricle contracts too early when they are not filled with blood

    Therefore causing little or no blood to be pumped out to the pulmonary artries

    Therefore there was no change at all in the pressure of pulmonary arteries during this contraction,


    I dont understand the Mark scheme but I got full marks in my mock so

    But I have a question- I haven't been on this thread recently... what's with all the people saying they haven't looked at the pre-release? Surely that's just making the whole thing harder for yourself...
