OCR Biology F212 Revision [3rd June 2013] (Now Closed)

Original post by Unsworth

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...

Thanks, always nice to have a guideline of what could come up!
But yeah, OCR will be bitches and do something like that... :tongue:

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 :smile:

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 :smile:
