AQA BIOL5 ~ 17th June 2013 ~ A2 Biology

I have only done an essay on causes of disease in human, just look at essay plans on mark schemes, and its amazing what you can remember in an exam

YEAH BUT THERE'S LOAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAADS OF THEM OH MY DAYS i really need to narrow them down to the essays most likely to come up, but i dont even know which ones those are!!!

Did you get the essay plan booklet thing they gave out in the final week?
I've just been using that and making plans for them and then making really brief notes on the things ive forgot :P

Would you advise recapping anything else and why particularly those topics? Thanks

Homeostasis?

Definition of homeostasis
Glucose levels
What happens to it when its too high? (islets of Langerhans, pancreatic beta alpha cells etc.)
What happens if its too low?

Temperature maintenance......
Vasodialation
Vasoconstriction
Heat from respiration
Ectotherms
Endotherms
Water potential of blood plasma needs to be maintained (otherwise cells become turgid/plasmolysed)

wonder if anyone could help me? I understand water can move through the root hair cell of a plant by the apoplastic and symplastic pathway, and i understand the route each of these takes. however does the water move by osmosis in both conditions? or diffuse? rather confused xxx

When you do essay plans or look over other people's essays or essay plans your will realise the topics you don't have a clue about haha, or things that come up regularly. Go over these.
resp and photo link into many different essays so that's why it's good to recap those. Also a good essay contains info from all 3 kingdoms; animals/insects, bacteria and plants. That's why I was saying to have a little look over plants

Great list! I meant I hope there's an essay on Homeostasis tomorrow

ive gone over post synoptic stuff like the cycles etc.. need to go over the bio5 stuff again but dunno what do to do for these essays :| just made the plan on the atp essay so far, which essays have you made plans on?

Hi could you please post the essay plan booklet thing as I was not given it

Thanks very much
Me
