    56744243[/url]]We all wasted a lot of time learning an awful lot of content that they didn't seem to care one bit about. Nothing on any actual biology! Though apparently F211 was like this, and I redid F212 and I can tell you it was all pretty straightforward and recall, so hopefully F215 will make up for it! Last year it was 63=A and 78/79= 100%UMS at an approximation!
    Last years paper was soooo nice compared to this one too! Less worried now because I'm pretty sure the grade boundaries will be very low. Wonder what f215 will be like? T_T

    Hope this year is similar, I think I got about 49-52 and I want an a*
    I think I could be on 52-54, but i need 100% UMS for an A* since my school messed up my practicals, so I've worked really hard for it! Hopefully it is about 40 for the A!

    For the question on why dextrose is added to the dialysis fluid, was the answer to reduce its water potential so that its isotonic with the blood and prevent haemolysis?
    That's what I put!!

    I did the same for anaerobic respiration, there wasn't much more to mention
    Argh completely forgot about the voltage gated channels and myelinated, would I just get three marks for mentioning, axon, dendrites and cell body?
    Yeah I think so, don't really understand the point in the question as it seems to be almost obvious in how they are similar? No idea what else there would be to mention so yeah seems like 3 valid points in my opinion.

    I guessed this and just said calcium ion channels remain open for a bit

    i said positive feedback too! total guess
    I don't think it was +ve feed back becuase the beta cells are not a target tissue of insulin. I thought it was a subtle hint at the refractory period in action potentials so said it took time for calcium ions to be pumped out of the membrane and potassium ions to re-establish the resting p.d.

    I wrote that then changed it to stem cells; bone marrow right at the end. Kupffer cells break them down, not make them.[/QUOTE]

    in my book it says that it recycles RBC

    I said that the ATP hadn't yet been hydrolysed so it was still making the potassium ion channels remain closed so ca2+ still came in etc etc
    I said this. I also said it takes time to metabolise the glucose into ATP so the process still continues for a bit longer even after the glucose concentrations in the blood fall.

    Pathogen causes fever, which is increase in body temperature.

    Why does fever cause shivering.

    Now shivering increases body temperature further so that's not the reason. This question was so difficult! I put shivering means increased respiration to produce more ATP to for protein synthesis to produce antibodies to destroy pathogen. Was really unsure about this.
