    for the light intensity question, wouldnt you talk about how light intensity is no longer the limiting factor and so c02 or something else must be - then explain this in terms of the calvin cycle?

    So annoyed. For the structure of shady leaves I wrote they would have more chloroplasts to maximise light absorption instead of talking about palisade mesophyll, for the light intensity question I forgot that stomata would be open for longer at higher intensities ffsssssssss, and I forgot about stem cells for red blood cells, and many other things

    Do you think the grade boundaries will actually be as high as 45 for an A?!
    Me and most of the people in my class found this paper harder than last years and that was 41 for an A so hopefully not.

    Posted from TSR Mobile
    I put that as well. I also said it may have a thinner waxy cuticle for the shade leaves just in case.

    the question asked how the plant is adapted to shady environment? how does a thick waxy cuticle help thats for desert arid conditions to prevent water lost by transpiration

    i put larger leafs, to increase surface area

    Phew!


    I put the cortex because it was a glucocorticoid. I'm not too sure though.
    it was defiantly in the cortex!!

    it said in the Q that the fever causes the set point of the body to increase, and therefore the body feels the need to shiver to increase its body temperature to the higher set point. Shivering causes skeletal muscles to contract which causes heat production

    huh, i wrote they would have i wider range of accessory pigments to absorb as much light as possible?
    i'm glad someone else went down this route as well

    I resat this paper and overall I found it hard. Too many suggest questions and not enough testing of the actual specification. The dialysis question was horrible. They gave too many marks for minimal points of the spec. so too hard to get marking points. I hope the grade boundaries are low but it depends how everyone else found it.

    Yes but also in that question we were told fever increases body temperature. Hence you would normally want to reduce temperature back to optimum via negative feedback. So why shiver if this increases temperature?

    I put interquartile range for the bars
    So did I, asked my teacher, and he said because of what the axis error bars is wrong, and it needs to be something about the range.
