    Oh myy.... My teacher gave us a booklet about airsacs and hinted that they could ask us something about them!!! He said "they may add something new into the syllabus for this paper" with a grin on his face... hmmmm.
    Um, im pretty sure they cand do that. Any changes in the syllabus/spec is announced at least two exam seasons in advanced, so atleast 6 months.

    On another note, can someone please sum up what we need to know about chapter 14? Its just a 2 double page spread on classification, but i dont understand most of it and i dont get what the spec is talking about for that section. How exactly do i define phylogeny?

    Phylogeny just shows the evolutionary relationships between organisms

    Do teachers see the papers before?

    Can you upload the booklet if it's in pdf?

    No teachers do not see the paper before, it comes in a closed envelope and they only take it out when they start to hand the papers out in the exam hall. The teachers get extra copies if there are any left but that is after the exam has finished.

    i'm sure you'll have a really nice one don't worry!
    what did your teacher say btw?
    Firstly, HUGE thank for the explanation. That totally makes sense now. It's just one of those things I needed to get straight in my head.

    Secondly, my teacher said that we essentially had the right idea between us:

    1. The leaves are thin so that all the cells within the leaf have some contact with air and therefore 02 all the time.
    2. They are large so that ther is a large underside (that will have many stomata) to allow air in and to increase SA for photosynthesis (see point four)
    3. Also, the Mesophyll spongy layer, the cells are loosely packerd and irregular to increase S.A further.
    4. Finally, respiration and Photsynthesis (obvs depending on whether it's day or night) help to maitin a concentation gradient and so lots of movement of 02 and Co2 in and out of the cells.

    Hope that helps.

    Got 99 in Econ and 91 in Core1 Math though, so I figured why not retake just the 1 unit as it shouldn't affect my summer exams really as retakes were quite early on.

    Is there a provisional mark scheme out for the EMPA (unit 3) we did? Or is that still not allowed yet? It would be great to know how I did >.>

    I don't know if you are just chatting ****. I never sat the exam so I don't know, I would need to ask somebody who sat the exam and does not talk out of his ass like you.

    My graph was messy because I had to change it...

    I'm pretty sure the one I changed it too was right though and if it's right im gonna get full marks even though it's an ugly looking thing lol !

    I used Relative Rate (1/time) sec^-1 I think?

    I remember some dodgy questions as well lol like why did you rotate the tube and all I could think of was to allow enzyme and substrate to be mixed properly or something and so you could identify when a curd appeared.

    Stupid stuff -.-
