FML pretty much sums this exam up. I tried to be smart and read through the AS book the day before and I ended up writing Clonal Expansion instead of Vegetative Propagation for the Elm question. For the last question I got 0.92 and 0.08 for the last question but put the answers on the wrong lines, knowing the w*****s at OCR they'll take two marks off for that. Now I've just done the worst thing possible by going over the paper.
Why is everyone (particularly on that facebook page) getting so worked up about the hedgehog question? Obvious three marks lulz:
1. Animal welfare groups believe all life has value in its own right. 2. Man introduced the hedgehogs to the islands and killing them is a harsh way to undo a human mistake. 3. Killing the hedgehogs will effect biodiversity and potentially food webs of the area in an unforeseen way.

OCR Chemistry tomorrow is going to be even worse.
I did the exact same! Don't worry, other people are lamenting missing out entire questions. Good luck with chemistry
can anyone tell me how to do the hardy weinberg, its seriously bugging me. it was 50 ladybirds in 296 that have the recessive characteristic, if that helps?

I think you got it the wrong way round. It was bb homozygous recessive for the red ladybirds (bb) and that was 296 of them.
so u do 296/ total(296+50 = 346) 296/346= q^2 q= root 0.855.... q=0.92 (2.d.p) according to hardy weinberg quation p+q=1. therefore, p=1-q, so p = 0.08
They were two seperate questions. Mutation and Natural Selection were the right answers (I think) for the question about how sheep evolved to be able to eat seaweed. The other question was 'comment on the ethical issues involved with killing hedgehogs'
I put mutation and natural selection for the seaweed question too but now I'm contemplating whether mutation is a process? I think the right answers were natural selection and evolution

i think i put natural selection and species isolation. it seemed like a good answer at the time :s and i seemed to remember something in the text book about for a particular group in a species to develop a characteristic distinct from the rest of the species they had to be isolated?

You were correct with Mutation and Natural Selection, mutation is definitely a process! Natural Selection and Evolution are pretty much the same thing, OCR often give you marks for either.

how do you know for sure? But thanks, you've given me some hope!
i would rather not think of that :P but i can say it was not an easy paper, far too many questions involved no actual biology...some people who did'nt revise were very pleased with themselves my college has alot of people that do maths and sciences and i can definately say even the brightest minds found it difficult...i now wish i did physics at A2 rather than bio!
aww, dont worry about it, hopefully the grade boundaries will be low enough for us to get a good grade
