1 markers are always the hardest.
Such as why synthetic EPO (or whatever) increased blood pressure?!

WHO KNOWS..
That is why we cannot make an unofficial markscheme with AQA.

I just guessed that was because it increases RBC production, more stuff in the same amount of space inevitably = higher pressure :tongue:

.

Only question on paper I couldn't be bothered to think through was why they used unit per mass and unit per time or something. Had lost the will to think through these crappy questions by then and just wrote some dribble :P.

yeah it was 3, I didn't mention diffusion but osmosis instead?

yes osmosis is correct, i didnt mention hydrostatic pressure but mentioned ozmosis and lymphatic system, hopefully that will get me 3 marks :s-smilie:

well, has someone offered a better answer than the competitive inhibitors question?

The question was about how its hard to identify its MRSA-so i said it could be a disease that is also resistant to methicillin but isnt MRSA.

And i found the 1 mark q's quite odd as well. I don't think i got the "why is it better to use 10 leaves when dealing with micrograms" one.

It would of been fine if it just said use 10 leaves, I didn't really get the relevance of the measurement though. I just said increases reliability, being able to use a mean etc :|.

For the frogs eggs one I failed greatly. I put since they are small they are overlooked by the pesticide sprayers and so are attacked by the pesticide....

DOH

I didn't find the June 2010 paper too bad when we went through it in class.
There was nothing on classification! I wanted it to come up !

For that one, I put that EPO increases the number of red blood cells in the body, so there are more red blood cells in a given amount of space, which results in a pressure increase.

Some of the stuff on there was really random though... ah well, that's what the 65% grade boundaries are for :rolleyes:

swiftylol

Same thing that always happens when I do these aqa biology exams

I open the paper thinking wooop easy Q's Lol.....

...Only to be stuck on the sneaky 1 markers and HSW nonsense thruout the paper D:

Hopefully got an A, but who knows?

- Sounds right, i said more RBC so when elastic tissues layer expands during cardiac systole this increases it but only 1 mark so that's a tangent. So nervous :frown:

Seen alot of people saying they found it easier than usual though. I agree with you though probably, the actual biology side of it wasn't really bad, but there just seemed to be alot more 1/2 markers that were hsw all over the place, and alot of them were pretty awkward to find what they were looking for.
