    How did everyone find it?

    I didn't think it was too bad but some questions had me stumped. Still think I did okay though.

    why did they need to count the dna fragments to ensure it had been fully digested?

    will i still be able to get a good essay mark with 3 well described points on the cycle one?? ran out of time but don't wanna kid myself here guys, don't think the examiner is gonna be best pleased ahhahahaha. pupa one was weird, for the reason there was a descrease in RNA did people write that there was a less transcription of the genes coding for proteins in pupa tissue as it was being broken down to release the amino acids to form adult tissue? and then for the increase in RNA did people just write that there was an increase in transcription of the genes coding for adult tissues??
    Yeah thats basically what i said. I said RNA levels fell in the beginning half because tissues are being broke down, not made etc

    And RNA levels were high towards the end because adult tissue was being made. ;D

    what!?!! :eek:
    yeah the first bold line i expected to be an hour, but it wasnt, i think the graph was 30 minute intervals, which was quite misleading.... could be wrong though

    I thought the 80% question was easy...

    the hormones was at the level exactly 2, and the nervous stimulation was at exactly 8.

    so they add up to 10... so 8 = 80% O.o

    Unless i missed the point and got it wrong.

    For the essay i went for the cycles, not sure if its allowed to put what i stated in it, but i went for menstrual, photosynthesis, respiration, nitrogen, carbon, (life in general for intro) and coudlnt really think of anything else.

    i got 5:1 or 1:0.2

    and like 80%, 57%, 48%, but for the last 2 i was think overal this had made by the 2/3 hours mark, not how much was being made at the 2/3 hour mark

    1st hour, nerve at 8, hormone 2, 8+2=10, 8/10 = 80, 2nd hour was like 8 to 6, 8+6=14 8/14 = 58 ish? 3rd hour 8+8.5 = 16.5, 8/16.5 = 48 ish?

    I said add up all the fragments and if it comes to more than the total length of DNA then you know its only been partially digested rather than completely digested.

    Paper was horrible...no muscle..no action potential and the bit with the mapping was soo confusing. Its so ironic how i thought i was gna mess up the essay and do okay on the paper but it was the absoulute opposite :/ ahh i was so prepared for nerve impulses and musclesss!
