    i swear you have to times the minutes by 4 to get 8 eggs? because 3 divisions makes 7 eggs
    no when cells divide they split into two so 1 would split to 2 then 2 split to 4 and finally for split to 8 three divisions

    For the evapotaion I put, the pesticide will become more concentrated as the water is evaporated off.

    6 marks is nothing, don't worry.

    Erm well that's rounded wrong, so I'm not sure. The number of DP would be okay, just would have had to put 55.56

    How did you work out the time for the cell cycle?

    I got 774? You had to times the minutes by 3, from what I've seen in questions I've done off the old spec.
    I got 2046

    I'm pretty confident the grade boundaries won't be much higher than normal, a lot of mistakes that a lot of people will make.

    I thought the paper was okay. No massive shocks. I'll have made some really stupid mistakes though so I will probably be looking at a C/D. Probably have high-ish grade boundaries.

    How..?
    Didnt the question say one cell cycle = 4hrs18min

    work out 8 cell cylcles?

    I did 4hrs = 240mins

    + 18 mins

    x 8

    Maybe I misred the question, I was in a rush :s

    Don't remember the exact numbers but they were basically diagnols in the base pairs, if that makes sense, lol. I think the only number we weren't given was 20?
