    That was my thinking too. And it did say "minimum phosphate required for growth" or soemthing - ie I think we can assume that it can survive without the 'junk DNA'.
    But we know that the 'junk' DNA is junk at all... it has a purpose, hence that question about why calling it 'junk' is misleading.

    it said minimum phosphate in soil needed for healthy growth against % of junk dna
    and it also said assuming that junk dna is junk

    but i still think its positive as when it undergoes mitosis, it cant not replicate the junk, so if it junk dna, then when it does undergo mitosis its wasting phosphates - so if theres more junk dna it needs more phosphates from the soil as theres literally more dna. however if it only has a little junk then it doesnt need that many phosphates in the soil as less are wasted with junk dna which are not needed

    why did a lot of ppl put 2.3micro metres.....that is too small to be measured.....the ruler showed 46mm, therefore it is surely 46000microcmeters

    I think because the picture was magnified, so you had to use the actual size = image size/magnification to get the answer, but not sure.

    Mag = Actual size/ Magnification so it was 46mm/20,000

    Then I multiplied it by 1,000... For some reason ah well. 1 mark.
    Overall I didnt like nthis paper.. But the strip felling essay was pretty good.. The ecology section was def the best bit.

    this paper was horrible! i got 2.3 micrometers for the first bit. didn't see 'to the nearest micrometer' eek! it was 46mm, so that is 46000 micrometers, divide by 20000 (magnification) is 2.3. for the graph thing i did positive correlation. i have no idea why. i cant even remember the question. i just got confused so thought i would draw a diagonal! i did succession for that q, and RNA for the other. i wrote SO MUCH CRAP. that one about 'why is a food web important in an ecosystem', surely it's just so animals can eat other things to stay alive! what a dumb q. i couldn't figure out what it was asking. i think i wrote about energy transfer too. i didn't look at auxins or plant hormones at all, because i really didn't think it would be on it. oh well, i was wrong! i thought that was an awful paper, but so were the past ones, so i was expecting it to be a killer. hopefully mammalian physiology and behaviour won't be so bad on friday. but knowing my luck IT WILL.

    Yeah, most people I've spoken to, including myself, wrote something along the lines of what you put. I mentioned energy transfer too.
