AQA A2 Biology BYA8 (17th June): Written Synoptic Paper

Wow, I couldn't have wished for a better paper! The last part of question 2 was a bit weird, but it's AQA at the end of the day. I did the water essay, simply because it's the only one I'd done previously for a mock.

What did people put for starch? I said it was a storage of glucose, but my friend put carbohydrates. Cellulose for support? Although it's in the leaf so I'm not sure..

For the reducing sugar one did anyone put that the red colour would be deeper with more concentred sugar solution, so using a colorimeter to see which let less light through would indicate which had more sugar in?

xi) Vasoconstriction of arterioles limiting milk[2]
less volume of water passes, less water absorbed to milk

For that one I put reduced blood-flow means less oxytocin can be transported to the cells of the mammary glands. Kind of a guess though..=/

Noooooooooooooo I put reducing sugars go blue! lol and that the more reducing sugars there is present, the darker solution gets... think there could be one mark there ? loll

blue.... hahahaha.. sorry man just made me laugh.... lol

Initially it is blue. It goes from blue to red. Easy mistake to make.

i didnt put that colourometer thing.... how many marks would that be? 1?

green means relatively little sugar and as it progresses from green-yellow-red it means amount of reducing sugar increases

I put "taste it, and see which is tastier"

That may just be on the mark scheme!

Was anybody worried about people leaving early during this exam? I think the first person left around an hour in?!

No one in my exam hall is allowed to leave unless they have to use the toilet or the time is up.
