    I said about dna and cytochrome c is this right?
    Looks right enough, I put down DNA base sequence and protein synthesis

    yes then i said dna sequence and embryology for molecular evidence
    I wrote the same thing. I think I love you <3

    The first two marks were straightforward look at diagram and write the labels. The rest were all fair as Your teacher will have taught you the theory, all you are required to do is apply the theory. It is not guesswork. It brings together several ideas on biodiversity and enzymes which makes it challenging but it is all in the syllabus. You just have to ignore the urge to start writing immediately and process the information. I did not find it easy, but it was fair.
    I'm not saying I couldn't do them; I'm sure I had a fair crack at them but I just think it's unfair that the first question should have so much uncertainty about it- surely the first questions should be recall, and then getting progressively harder? We'll just have to agree to disagree on this one methinks -.-

    oh yeah of course. It said hyphae. That gives the game away
    ya
    what did you keep about how after a long time you can know whether its same species or different one?

    I think this was the only question where there was mention of student when the E.coli cannot break down agarose.
    think I messed that up coz for that I wrote about speciation coz its the one which determines about difference in species.
    I said DNA and Cytochrome C

    The question about how 18th century farmers how they could create better sheep, did you have to talk about; artificial selection? like isolation, selective breeding and then line breeding?

    oh ok. protein synthesis might be right too m not sure about this

    i said that too haha, it was a guess xD
    Ahaha! I hope we're right

    Is it possible to genetically modify sheep? O.o

    haha ya it did. I liked the paper.
    how was urs?
    meh a lot of suggest questions i guess, but not bad, could be worse... messed up the variaition question i.e did not write out about continuous and discontinuous, put protoctista instead of fungi etc you?

    put embryology and looking at anatomical, physical biochemical features but pretty sure this is not after a long time...!

    I said DNA and Cytochrome C
    this was about other two evidence
    i am talking about how over time you can be sure they are same species or not?

    EVERYBODY DO THIS!!!! If they receive a lot of complaints about this paper, it might make them lower the grade boundaries more!!!!!
    *goes off to write a complaint*
    Waste of your time, no they will not. If you read the past examiners reports you would have realised examiners are pleased when there is a difficult paper as it really shows who are the best students and who are the coasters. Do not waste your time writing to the exam boards as they are not meant to be your friends, they try to give you a paper which truly lets those with intelligence excell.

    what did people write for the variation question? i wrote genetics, environmental, anatomical, embryonoic.

    can someone put my mind at rest lmfao
    for the way methods changed when breeding cattle since the eighteenth century or some ****,
    i put antibiotics, crossed it out and put artificial insemination
    AKLSAESOHJ is this even slightly correct
    p.s so ****ed
    I put artificial insemination too.....

    Lol, I put "sequence of DNA" and "sequence of cytochrome c"

    Couldn't think of anything else. Worth a shot =/
    I wrote these two, but just as "DNA" and "Cytochrome C"... eek :eek:
