    What did everyone put for the butterfly question (part B) what would have made the scientists results more accurate... I said they should compare them to other butterfly's living near nuclear power stations or something like that?

    I put about peer reviewing and looking elsewhere for similar situations that help prove the theory, I hope it's right!!

    I said they should measure approx. how much radiation the butterflies may have come in contact with, at different distances from the spill

    I wrote that they should compare DNA to see evolutionary differences, and difference in species. I also stated that they should increase the sample size to gather an accurate representation of the butterfly population (for reliability).
    Oh and I put 800% for that question, I'm pretty sure that's correct because 160/20 x 100 is 800%

    But I've most likely completely messed the whole paper up.

    I attempted the question like 10 times and got different answers each time! Can you explain please how it was 700%? (Although it's over now)

    I remember one reading was 20 and the other was 160

    It asked for percentage increase (which I didn't read) so to go from 20 to 160 it increased by 140. 140/20 is 7.
    7 times 100 is 700.

    Sorry I'm bad at explaining

    I'm glad it makes sense to you now I didn't realise until after the exam that I'd done it wrong. I think many people misunderstood that question It was tricky
