    Yeah i wrote create average, then compare with the other
    I got the frog thing wrong, totally! Forgot about SA:V ratio.
    Got 9 for the amino acids? I think..
    then the second part i wrote about introns and multiple repeats which im not sure is correct
    9 is right!
    and yeah for the second part you had to write about introns, which are basically bases that are non-coding.

    I got this :3, wasn't too sure though! It was just a guess
    I was gonna put this but then I thought it can't be that simple...the question was asking HOW they measure the EPO concentration in people's blood
    I put they could count the number of red blood cells in various samples of blood from healthy people as this would be proportional to the amount of EPO (more EPO=more red blood cells)

    i wrote it allows comparison as the patients body mass differs?

    Take blood samples of healthy people, and create an average conc of EPO in their blood?
    But the athletes may have different levels of EPO to other people.

    I must have read the graph wrong because I didn't get 9 at 1996 I read it around 9.6, so got a percentage of 45.8%. Ah well that'll teach me for rushing.
    Dont worry about it!
    it was only two marks and a lot of people will have stuffed up the calculations.
    You can always retake it like i've just done, so no worries

    Ermm only a positive correlation, there may be other factors effecting the rate.
