    What on earth was that genes question about drugs in the body? Enzymes? Conversion? It stumped me completely
    I wrote some genes are resistant agaisnt certain drugs and thus passed on to offspring.
    Edit: whoops got confusied between this and antbiotic resistancy.

    I put boy. One of my friends put the girl but I see it as if you got cancer on your arm due to exposure to ionising radiation, your child isn't going to get it too so for it to be passed on the damage would have to be done to the sex cells
    Yeah, I put the boy too, because it's an environmental change that cannot therefore be passed on genetically- but I was a little confused as to why they would have 'genetic changes' in their cells because of radiation, so...

    I also cannot do percentage change...


    I got 33.3 recurring?!?! But most of my friends got 700.

    Probably some of the easiest 6 marks questions in any OCR paper ever
    Completely agree, never felt so confident about a set of 6 mark questions before

    I have an A* in maths from taking it a year earlier than 80% of my year at school so should be ashamed of myself if I got the percentage question wrong but none of my friends got 700

    Well, I haven't got a clue... I haven't the foggiest what calculation I even carried out!

    And I'll guess we'll never know as we don't get the papers back

    It's kind of annoying that we don't get the papers

    Yeah,even though I'm never doing biology again, I still really want to know exactly how well I've done- not just a final overall grade

    Is this for the GCSE triple science exam? Because we have ours next week and thats OCR B1,B2 and B3. Just wondering if this could somehow be the same paper just sat earlier by various places?

    Anyone think that the grade boundaries will drop? For Physics P4 P5 P6 last year (June 2014), 33/60 was an A* which is probably because everyone did not do so well. It seems as if most people did not do too well on this paper either

    If it's ionising radiation it can knock electrons of atoms and alter the DNA :eek:

    I wrote about it being a different sperm and egg and how that makes them genetically different because of the various different combinations of alleles that come from the parents
    I wrote that there are 2 fertilised eggs, and one splits in two whilst the other stays the same, which is why babies A and B are genetically identical but not baby C :confused:

    Grade boundaries will be high for this B1 B2 B3 exam I think

    I agree. It was a pretty easy exam and they won't just give you the marks easily.
    Biology has the highest grade boundaries out of the sciences.
    Physics has the lowest grade boundaries because it is generally harder.
