    What did you put for why increase in phosphate meant the embryo was growing? I had no idea, I think I wrote something about the presence of phosphates in DNA and cell membrane structure but I'm not sure if that was the sort of stuff you were meant to talk about.

    I think it's just simple diffusion.

    Yeah but 2.86 and 2.9 are the same, did it say to how many significant figures?

    for the FEV and walking up the stairs question I didnt refer to oxygen as it was about the max vol of air breathed out (didnt say about breathing in) so i said it couldnt expel the co2 rich air, a build up of lactic acid would form causing pain and fatigue

    Yeah I got 70 for the SV. Did you get 66.7 bpm? I have a feeling it's wrong because it might be a trick question, idk.

    Also, I got 2.85 (or something like that) times higher after calculating the area using pi r squared and then divided? No idea if that was right as some people just divided the diameters directly.

    I got 2.86, and for the tick box I got 75 but my original answer was 66.7 too so I see what you were thinking- I'm not sure which is right to be honest
