I'm using the cgp revision guide, ann fullick textbook, my notes, and the SNAB revision guide.
You know in the ann fullick text book page no 212 and 213... do we need to know that ?? :s-smilie:

Cgp revision guide
Pg212-213; the bit on the far left yes
2nd column not too sure, that looks dodgy, never done generator potential before in class, not too sure it's on spec too
3rd column we should know

Oh gosh, just had a quick read of that and I'm stumped.
I think for adaptation, receptors show a decline in activation so less action potential produced hence less frequent reactions.
Not too sure how it's different to accommodation
Good question though!

I really don't like the idea of this article :s-smilie:

I don't really like unit 5 either, or unit 4 which I'm resitting :-(

Me too :/ I am resitting biology unit 4.. I keep getting B from biology a level .. And i keep resitting as I need to get an A :/ .. good luck to all of us. By the way, can anyone share the questions that may come from the article if they have any questions or materials given by their teachers?
