OCR Biology: 08/06/2010 Molecules, Biodiversity, Food and Health

too much maths!
i find enzymes ok, cuz humany stuff interests me...but biodiversity (and that whole section) is too boring *yawn*
quick question: do we have to know about the roles scientists played in finding out about dna, like Chargaff and Griffiths etc?
and, do we have to know what the organic bases look like, like adenine is a ring like structure etc?

Imagine what was running through our minds about being the first ones to do this papers. meh that was a horrible paper when we first done it in June 2009, lot's of people thought they messed up after they came out of the exam room, got an A on my retake. Just learn everything thoroughly, OCR can be unpredictable.

After lookign at the June 2009 [first time i did it] and the Jan 2010 resit of F212 paper..

Jan was wayyyyyyyyy easier..
now cos OCR really are unpredictable you dont know what will happen..

i've still gotta cram immune system.. vaccines and drugs..smoking..diseases...biodiversity..and conservation all by the end of today..

is there any point in learning the DNA stuff? or Biochemistry stuff?

whats people's opiniions on the long answer question to come up..?

I underestimated how 'How Science Works'-y this paper would be. Knew all the stuff but not so great at noticing links where it's been applied differently, if that makes any sense?!

The June 2009 had a last Q based on smoking, about 10 marks based on it, and another 9 based on a graph/results of a smoker/non-smoker study.

I haven't seen a lot on Malaria/TB/HIV in the past papers though.

I hope traps/methods for catching animals comes up... Hit tree with stick - catch falling things on white sheet - this is like the peak of my scientifical biology knowledge

I don't think we need to know the roles of scientists, i haven't seen it on the specification, and we haven't been taught it.

I just think we need to know that adenine and guanine are purines and uracil, cytosine and thymine are pyrimidines.

didnt know that, but now i do - thankss
wasnt the specimen paper almost entirely biodiversity :/
maybe they'll forget to put that whole part in, and only make it about human stuff - thatd be good (like chemistry - no green!)

im retaking it, so at least ive got a c in it if i screw it up
but yeah im good on everything mostly, apart from the stuff on the immune system, like how the t an b cells work, but i do get the primary and secondary responses, so if anyone could help me on the t and b cells that would be great

Couldn't agree more!!!!
