    anyway, can I write 'no' calcium ion enter the presynaptic neurone due to inhibition of calcium ion channel instead of 'less' calcium ion, so subsequent statement would be all 'no' vesicle fuse, 'no' neurotransmitter, 'no' depolarisation...

    can anyone explain what answer will be like ?
    I pretty sure its about that rhodopsin thingy. I wrote:
    rhodopsin bleached to opsin and retinal, sodium ion channels closed, so no sodium enters rod cell. Sodium ions continues to diffuse out, hence, hyperpolarisation of rod cell. No neurotransmitter released. So, depolarisation occurs in bipolar cell, initiating action potential. Nerve impulse sent to brain via optic nerve.

    Can't really remember what I answered. I think I said something about drug B (the one that last for longer time). I wrote quite a lot and pretty much made up everything to seem logical >,< what did you wrote?

    Me wrote about A >< strong and in shorter time, suitable for dental surgery which unlikely undergoes more than 2-3 hrs ... How did you calculate the population ?

    dangg, That's more logical tho. didn't think of that. erghhhh. erm. Are you referring to the scarecrow question? I think I wrote about calculating the percentage of crops eaten in the area. Not sure if its correct tho. I found this was the hardest part for the paper.

    Oh nah, I mean the question of population suffering from AD. Btw that's similar to mine answering the habituation investigation

    I calculate the population by 85million x 10% x 10%

    I talked about both drug A and B. Maybe jaw surgery is also counted as a dental surgery which takes a much longer time? so drug B can be used in this case I guess...

    I think this question is open form, able to discuss two drugs provided that valid reason

    how did you answer the consequence of decline function of T cell? Is it fine to just state the function of it like t helper cell activate B cell t killer cell destroy infected host cell sth like that, and mention those ppl would be more susceptible to diseases? And what did you write about the last question
