B2 aqa may 16th gcse answers here

i said that the mammal lost more energy through heat because it was warm blooded whereas the insect didnt so it could use more energy for growth? only thing i could think of

found it easy. i mean i didnt miss out any questions and had a good sight on what the paper was going to be about anyway as i spent 3 days 12 hours a day memarising the whole b2 book!

but what did you guys get for the large insect and small mammal percentage question? i honestly put down 6.6% (added all the kj's up then 0.64 divided by 9.6 or something x100) reading the question more thouroughly it said the eating energy and that was just 4.0 so i changed the awnser to 16% what about you guys?

and when the walker fell. he was more likely to die because the alchohol affectted him becuase the blood vessels cut out cos thermoregulatary centre responded to his cold body when he drank the alcohol?

I put something like because the blood vessels near the surface of the skin vasodilated due to the alcohol there was increased blood flow through the capillaries close to the skin so more heat was lost (I put through radiation but I don't know whether this is correct).

Ooooh that's what I put
Are you 100% sure that's the answer? I've seen what other people put, and even though it's completely different, it sounds correct!:/

I think it's correct because it links in with homeostasis. To me it seemed by FAR the easiest b2 paper I've tried even though others are saying it was really difficult. Anyone else agree?

I found it harder then I thought it would be... D:
Usually I have about 5 minutes to check everything but today I was still writing right until we were asked to put our pens down. And I misread the second last question and added all the numbers together to find the percentage of the total, but then I realised my mistake a few seconds before the exam was over and when I changed it I forgot to change my final answer from a decimal to a percentage because I was panicking.... ):

Luckily my Chemistry mark will bump it up but hopefully the grade boundaries will be low. ):

By the way what was the answer to the second part of the first question (About why animal cells explode with too much water and plant cells don't?)
