Re: AQA BIOL1 ~ 14 May 2012 ~ AS BiologyYeah i'll just make it up if it does. I've never seen a 6 marker for asthma, but anything is possible I guess(Original post by Jakez123)
as far as i know you've said all marking points, i think the mast cells/histamines and mucus bits are just extra information although i'm not entirely sure.
EDIT: i realized that it might depend on the number of marks you can achieve on the question, maybe if it was a 6 mark question you would talk about everything about how mast cells produce/secrete histamines which cause inflammation

Re: AQA BIOL1 ~ 14 May 2012 ~ AS BiologyHonestly could be anything.(Original post by Jakez123)
What do you think the 2 5 mark questions are going to be about?
I'd have a wild guess and say.. lung diseases and absorption of starch or something to do with small intestine absorption.
I'm also *pretty* sure we will get something on ultracentrifugation, as its not come up on the past few papers x

Re: AQA BIOL1 ~ 14 May 2012 ~ AS BiologyWhen you homogenise a cell to release its organelles. Then filter is to remove cell debris and completely cells.(Original post by Jakez123)
What's ultracentrifugation?
Then put it in buffered, isotonic, ice-cold solution and spin it in the centrifuge.. etc etc.
It's pg 41 in your text book x -

Re: AQA BIOL1 ~ 14 May 2012 ~ AS BiologyOh, it seems that i knew what it was, it's just that i call it "homogenised centrifugation" which lead to a misunderstanding. Sorry.(Original post by britash)

Re: AQA BIOL1 ~ 14 May 2012 ~ AS Biology*pokes previous posts*(Original post by BelMa)
Hi everyone ! Any prediction on what they could ask us for the 2 5 marks questions at the end of the paper ?
I reckon...
Something on the lung diseases.. like emphysema or something.
Also something to do with absorption of starch or how the epithelial cell is adapted for absorption.. -

Re: AQA BIOL1 ~ 14 May 2012 ~ AS BiologyBiology psychology sociology and philosophy. You?(Original post by thescientist17)
Oh no
there is so much to learn though, so many little details. Well at least it'll all be over soon. What other subjects are you taking?

Re: AQA BIOL1 ~ 14 May 2012 ~ AS BiologyIf your school has a Kerboodle subscription and you've got a login, you may be able to find bits on there? Otherwise your best bet would be a library.(Original post by AAA_)
