    What did you put for the classification one? That was like almost a trick question but I read it again like 5 times because I was paranoid

    I somehow got the base pars one right, after like 7mins of thinking
    Which classification one? :O cant remember

    Oh yeah was it just me that found the fill in the table of A's T's C's and G's a bit awkward? Or was it just because I didn't read it at first.

    I thought strand A was a piece of DNA and strand B was a piece of DNA at first, as opposed to them being the 2 strands of 1 piece of DNA. And I read 74 base pairs, as 74 bases xD.

    Guessing it was supposed to be A's from one matched T's from the other, and C's from one matched G's from the other. And total adding up to 148 bases .

    Think that's what I ended up doing in the end.

    was the frog egg question why the frog eggs were more or less prone to the effects of the pesticide :s I have feeling I wrote the answer wrong, cause I wrote an answer for why the eggs would be easily 'attacked' so to speak by the pesticide.

    the person who was saying cell wall is cellulose in plants is talking RUBBISH. Prokaryotics have cellulose cell wall, eukaroytics have peptidogylan. BUT THEY ARE PLANTS. K THANKS BYE.
    What fish question?

    And Loooool I knew that animal cells dont have cell walls when I was in primary school... A level students not knowing that is worrying, oh well atleast they bring down grade boundaries

    The question was about how its hard to identify its MRSA-so i said it could be a disease that is also resistant to methicillin but isnt MRSA.

    And i found the 1 mark q's quite odd as well. I don't think i got the "why is it better to use 10 leaves when dealing with micrograms" one.
    I wrote that 1 leaf wouldn't weigh very much, but 10 leaves would have a weight :s

    DNA Hybridisation, with the table asking which to were most paired. I put the top one I think, as the bottom two were both the same species.

    Yes 55.56% is the general answer most seem to have gotten. So yeah, pretty much confirmed unless 90% of the people here are wrong .

    Why is cell wall any less safe than chloroplast and starch storage. They're all right.

    i really cannot remember!! =(
    But the one after i talked about more temp needed to seperate the ones which are closely related etc.. hydrogen bonds. I dunno i've dropped so many marks i can see my self get out of the 'A' boundary.

    Ooh yeah, I was like WHY have the bothered putting in the "hybrids" from the same species :|. Just made the table confusing to read, but yeah it was Grus americano (or sumit) and Grus monachus I think. As they had the highest % hybridisation out of the 3 non-same-species data.
