    That sounded like an horrific paper haha
    Yeah it was pretty bad! I did it as a mock and I'm just so so glad it was January and not one that could have been ours tomorrow The grade boundary for an A was like 71 though so you could drop almost 30 marks and still have gotten an A which seems like quite a low boundary to me!

    i will put forward my guestimates of what i think may come up, but take it with a pinch of salt :u

    - dna replication
    - immune response
    - smoking/smoking diseases
    - water
    - compare & contrast a globular/fibrous protein
    - conservation in situ/ex situ
    - domain/kingdom classification system contrast/compare

    but as it's ocr they may just make half the paper on enzymes like last summer...
    please make it this!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!1

    just done the June 2012 paper... haha what a joke. :/
    It's going to be a real pain if the bulk of the exam tommorow are "Suggest"and "How science works" type questions- would have spent hours memorizing the Bio spec for nothing!
    praying for a good, content-heavy paper tommorow! (unlikely though- it is OCR afterall..)

    Animals in natural habitat, behaving normally
    Maintains biodiversity in that area


    Hard to get food to animals
    Hard to observe animals over a large area
    Difficult to prevent poachers 24/7

    What is everyone doing today, as it's the day before the exam?

    I'm personally just reading through everything, double checking. I'll flick through papers for a bit with a mark scheme, then relax for the evening so I am fresh tomorrow morning.

    As there may be more than one strain that year, say there is flu 1 and flu 2, you have to have vaccines for both!
    (Unless if they stick both dead forms in one vaccine... Then my argument is invalid:s )

    Correct 4 marks

    You could also say:

    • Less disruptive then removing from habitats
    • Large Populations can be protected
    • Recovery is greater (than ex situ)

    But you got full marks from your points
