    Ok, i'm freaking out!!!


    WHAT and WHEREABOUTS was the electron transport chain q, because I CANNOT remember doing it!!!! ??!!!!
    There was a 6 marker on it at the back of the booklet.

    oooooooooooooh you missed it :shock:

    It was in the very first question, the table, which looked like this:

    photosynthesis | aerobic respiration | anaerobic respiration
    produces ATP
    in organelles
    involves ETC

    I almost missed it out actually, I did 1 b) first & then looked up! You probably just forgot you did it because it was such a short one & the very first question.

    in my book it says birth rate = number of births each year for every 1000 people in a population.
    I just said "The number of births within a population over a period of time". Not specific enough?

    ****e. There goes a mark.

    I think I probably got 63/72 altogether.
    haha no worries man its just a mark. I dunno what i've got but looking at the questions im guessing roughly just above 50 I HOPE. I really need an A in this paper so im begging its ok.


    for the human pop questions i put:

    1.Describe the data
    - Life expectancy in UK is greater than in Sudan for both males and females (stated the values) ... In both UK and Sudan, life expectancy for females is greater than males (stated the values) ....

    2. Explain
    - Sudan is an LEDC - poor sanitation, healthcare, diet. In general, a lot more men are sent to war than women, where they are more likely to die than if not going to war.

    LOL i couldn't think of any other reason except war??! so stupid but i dunno it might get the mark?? what did you put?

    Let's get ourselves on here by complaining about HSW questions.
    Yeah they might lower the grade boundaries.

    I put the same, something like "the number of births in a population during a given time frame (usually a year)". Per 1000 never even occurred to me, I suppose I thought it depended on population size.

    Flip i put nautral selection :/ i was gonna put directional but i got confused:/
    it did say what type of natural selection is this? aha but i couldnt think so put selective pressure then "survival of the fittest" and in the explanation put something like the ones with the functional enzymes will survive and pass on their genes whereas the ones with dysfunctional enzymes wont.. its only 2 marks! be fine.

    (please say it was, otherwise I may have missed a page out!!! :O )

    dunno they might want the out of 1000 thing. I said, the number of births in a population in 1000 ...... dunno why i said 'in' 1000, bad use of the english language lol. hopefully got the mark. im sure other answers may be acceptable though!

    btw can you remember if there were any other questions after the 1:1 ratio one and if so what was it? not the genetic cross one. and was the genetic cross one worth 3 marks? also for the one did you get two different genotypes for the black fur section... and then 1 each for the other two (choc and cinnamon) ...

    I said same as you for describe without quoting the data, I didn't see the point.

    For explanation I said healthcare in UK was more widely available, Sudan was a poorer country and food was less likely to be available. I then said male's are more likely to die due to y chromosome being shorter than the x chromosome and so some less desirable traits on the x chromosome of males will be expressed even if recessive due to no competition.

    Joking, I just said about healthcare and food

    i put the exact same things you have except I didnt put war in. For some reason though - war was the first thing that came to my mind. So I Just put that uk had better nutrition, sanitation and healthcare.
