    Me tooo
    The first set of pages was awesome
    then came onto the hsw questions
    :eek:
    Yeah, so many random 2 mark questions about nothing interesting. I got bored so counted them and there was 26 lol.

    Knowledgey questions seemed pretty reasonable though .

    I didn't realise I completed question 2. I was writing some answers down for question 3 and I checked the time and about 15 minutes had gone, I was like that was quick, when did I do question 2?

    I went back and checked and realised question 2 was worth 4 marks, like wtf?!

    Ohh :L
    LOL
    I'm quite worried in terms of the markscheme, loads of people here have written different answers for the same question

    I know what you mean... I would hate to ever think I'd done well then not. That's never happened to me but that would be awful!

    Haha, thanks. I'd rather Bio was in the morning but ahh well.

    I have Chem on Fri then French on the 6th, joy. :p: Tomorrow is my 1st exam. Dw, revision will be done soon, no more for like 7 months!
    Sorry for the late reply thought it was time to actually start revising
    hahaa.. how did you find it? I thought i went okay..

    Can't even remember what question 2 was about >.

    Oxygen dissociation curve page was only 5 marks too, and like 3 of them were tissue fluid .

    why B has a lower change in mass or something
    i basically wrote about a reduced water potential gradient, thus losing less water etc..

    Oh gah that one I just wrote alotttt of different stuff haha.

    Went for some stomata covered by grease so water will take longer to diffuse out, also said the actual thickness of the leaf will be increased, increasing diffusion pathway so water loss is reduced through the leaf. And put less light will be able to be absorbed (no idea if this is true :P) so less photosynthesis will be taking place, hence less exchange gases required and stomata can close. And about water potential.

    Was a "**** it go for a mark " question .

    I put that that in B the grease covered the stomatal pores which did not allow water to leave through the stomata which prevented loss in eater which reduced loss in mass not sure if that is right tho
    well i thought it didnt completely prevent water loss, because on the graph it did show water lost from the leaf covered in grease so i wrote it increased the distance of the diffusion pathway therefore reducing the amount of water lost :confused:

    No, it doubles each time:

    1 cell splits, so 2 cells produced. These 2 cells split, so 4 cells produced. These 4 cells split, so 8 cells produced.

    3 cycles required for all that .

    some animal cells have cell walls.... its cellulose cell walls that are only in plants?
    I'm pretty sure only plants/prokaryotae have cell walls.

    You should of drawn it out in the exam.

    C will represent the cell:

    C
    C C (1)
    C C C C (2)
    C C C C C C C C (3)

    work together, someone make a new thread, everyone puts down all the questions they can remember, suggests answers are used as the real asnwers. done
