WJEC BY2 Biology AS - 1st June 2015

I said it goes from egg to larvae, then to pupa before becoming an adult

Can someone create an unofficial mark scheme please? I'm sure many people will want it!

Also what did people get for two differences for the butterfly Q?

What did you get on the question about movement of blood flow from atrium to ventricle, and ventricle to aorta, and the other one? (letters)

On the aveoli question was it blood cells or blood vessels?

On the aveoli question was it blood cells or blood vessels?

I said there would be a pupa stage in the cycle, and that the initial lava would not look like the adult/imago

I put A C E i think

They were blood vessels on the diagram I think

Cos I used that as one of my answers: good blood supply, transport, maintain conc-n gradient

YESSS I put those two! As well as loads of other things...



Hey, I put that too, but do you reckon it was ACD? http://classes.midlandstech.edu/carterp/Courses/bio211/chap18/Slide23.jpg

Not sure what the last Q was but perhaps it was isovolumetric relaxation?

It was ACD that's what I put, I think you could have however had a different letter for the first and last box, D could have been B I think, because it stressed 'a' in the question, implying there were more

A C E but not sure on E



I said vertebral column.. what else could it be?

Ah man! Glad it was just 1 mark.



Fair enough
