    That was seriously good. I really, really, really appreciate that. How you turned 2 pages of notes into 1 sentence.

    I dont know about your plans for the future, but looking from the rest of your post, you'd be great as a private tutor (as a student job or something). Rep to be given too...
    Lol thats nice of you.. Glad it helped Haha i'll consider tutoring

    How did you find todays paper? Ah i want the answers!

    I was not pleased with that paper. It's as if OCR designed the paper to specifically target the weak points in my revision. <_<

    -Find the difference between percents, and water potentials to be 19.444444, then multiple that by 7. Add number to -1850? <- I did it this way, but I think it may be wrong. I ended up getting -1664

    I did this one, it seemed obvious to me. Overall I think it was an ok paper really, nicer questions than I imagined.

    Will they EVER do a question on the heart though? I swear on this and all past papers of the new specification there hasn't been one. My teacher suggested they may be saving it for a synoptic question for the A2 paper

    for the people who did this exam as a retake- what did you get in the first/second time that you did it? did you find this one harder?
    from reading some of these posts, it seems to me this exam was harder than jan 2010. i got 100% in it back then.

    yup, it was 2 marks the symplast and apoplast is how water travels across a route however this asked about cell membranes

    2 Functions of cytoskeleton?

    -1700 anyone?
    -1800 I got. My teacher did the exam paper whilst we were doing it and she got -1600.. she said there is likely to be a range and she got -1600. Maybe we have hope

    I got -1600 because I ran out of time and just had a guess. Im pretty sure thats not the right answer though if you work it out mathamatically. Im suprised your teacher got that.

    Let's hope bronchus is right then xD

    For that water thing - I'm pretty sure the question was, "How does water move across the cell surface membrane?"
    Surely symplast and vacuolar are describing what the water does once it's passed through the plasma membrane, not describing how water actually enters the cell in the first place?
    I put that water on its own is small enough to pass through the bilayer via osmosis, but if there are solutes / larger molecules with it, then channel proteins may have to facilitate the diffusion.?
    Bronchus? Why bronchus?.. I thought its trachea then bronchus then bronchioles then alveoli????!! My teacher said it was bronchioles!? :confused:

    i took F211 originally in june, and spent the whole hour very stressed out, due to waking up at 8.52, sprinting to school (only live round the corner) and spending the 1st 10 minutes out of breath (i wasn't in school uniform either haha, just joggers and tshirt)

    anyway, i found this exam alot better. i finished with 20minutes + to spare. Probably because i did a mad amount of revision because i'd learnt it over a year ago, so wanted to make sure i was okay with everything.
    I got a 59/90 last time, so hoping this will push my overall UMS up from 240 to at least 260

    God knows.. i have no idea how I got that. I think I did some subtracting and dividing.. im not sure. Hopefully they have some range!! Did you get bronchus or bronchioles?

    I did this as a re-sit. For me last year, it was lack of revision and no exam practice so I got 61. June paper went really well so i re-sat this but i found this paper quite similar to ours last year cos IF i had done ALL my revision very well with exam practice that paper should have gone wowwwwwwwwww.. but i didnt so..

    I said 'growth and protein synthesis', is that right?
    well, thats G, S and G2...so yes

    For the bronchus/bronchi/bronchiole debate, i thought about it for a while, then decided that the alveoli connect to the bronchiole, and the bronchi lead off from them, so i put bronchi.
    It wasn't bronchus because there were two branches of it.

    I put its responcible for the movement of organelles inside the cell, e.g golgi vesicles
    and there seemed to be extentions coming out the cell so i assumed they were flagella. So they were responcible for the movement of flagella.
    :rofl: This made me laugh for some reason. But I see what you mean. I just winged it for that question though.

    with the water potential question did it specifically say when 50% were plasmolysed? I didn't know what water potential to state because i didn't know at which % plasmolysis it can be considered to be at the water potential.

    Well theoretically it should be -1664 but I just said -1700 as it was an estimate
