Yeah, I got 8% from using the lower value.
A friend of mine thought you might get a mark for using the median mortality rate, aka, 15%, but I'm not so sure - It was only 2 marks, so I figure one for appropriate working, and one for the answer.
I'm sure they'll use the range of 8-16, as they ideally need to appease to the optimists and the pessimists, plus the inbetweeners :P

also what did you answer for the 'why is it a problem that WAT is in a big mass rather then in droplets for blood presssure'

Was that the question?
I thought the question was, why do lipids in BAT exist as droplets rather than one big mass?
Anyhow, I didn't really know how to answer this. I put something along the lines of, small droplets are easily transported in the body and since BAT contains ucp-1 protein, distribution of heat is more efficient.

Wasnt the question along the lines of why its an advantage that BAT is stored as droplets rather then big mass.... ? Or was this another question?

probably, i cant remember. Only that there seemed to be no connection to any point in the specification at all, so i just guessed that if the fat is in one big mass it would press on the arteries and increase blood pressure, probably totally wrong

That question made me lol. (Not literally, as I'd be DQ-ed xD)
4 marks? It just seemed like a waste of a page :P

That was the question.

I put something about a greater Surface Area:Volume ratio in smaller droplets, therefore it is broken down much more quickly and can release energy quickly.

but I remember I was in doubt with the second one, as that could be interpreted both ways. However I forgot the question entirely lol, can someone post those?

It was about the advantages. I just said it had a higher surface area, so enzymes that break down the fat can get to it easier, allowing for the rapid generation of heat :s-smilie:

oooh at least someone put the same as me! :biggrin:

haha
bit of a strange paper on the whole.. didn't really feel like you had to know that much actually biology to really answer the questions...
loved the multiple choice questions at the very beginning!

Guaranteed 8 marks on multiple choice questions alone! :biggrin:

But I know my friend doing the exam put the same thing as you, so I'm relatively unsure :s-smilie:

I think the 2nd one was like "Phytochromes can respond to all wavelengths of light"

Which is false because they can only respond to red/far red light?

I hear you there. Too much analysis questions, not enough actual questions.
Barely anything on muscles, homeostasis or aerobic/anaerobic respiration either :angry:
