    i got 3:3:1:1 too...

    the last question about the multiplying bacteria, was that talking about the limiting factors? eg, lack of nutrients, lack of water and accumulation of waste products? coz thats what i put

    also, the question about the cyanide, i put that energy wont be produced because the final acceptor isnt producing water and making 34ATP, so anaeobic respiration has to be used, but this is short lived and produces hardly any energy, so cells cant respire and and so the muscles die.. that right?

    for the tissue question that secretes the glucagon and insulin, i knew it was islets of langerhans, but i wasnt sure if it was a tissue so i put the pancreas, so i think iv got that wrong. what does every1 else think?
    The pancreas is an organ, not a tissue.

    I'm really pleased with how the paper went. Although I think the grade boundaries are going to be higher!

    I put something like the alkaline conditions and our body temp may not be favourable. I also put something stupid like the bacteria in our gut might attack it, as well as white blood cells. But then I thought I prob should have said something like there's not a huge amount of nutrients, becuase especially in the large intestine, most will have been absorbed. Oh well, its over, at least there's a positive side!

    I wrote for the multiplying one.
    -Agar is more nutrient dense
    -More space in large intestine?
    -Intestine has a more constant supply of nutrients- not sure about it really.

    I thought overall it went ok, but i messed up the genetics question .

    1. Temperature in the intestine is unlikely to be the optimum for growth.
    2. Competition for nutrients with other microorganisms in the intestine.
    3. pH in the intestine is unlikely to be conducive to rapid growth.

    i put lack of nutrients, oxygen and accumulation of waste products

    are these correct?

    Also, did every1 get 26.2 minutes for the generation time?

    Anyone find that question on refractionary period and why it was neccessary a complete b*tch? i put that it stops AP's being generated to frequently and therefore the strength of a signal not being too strong but i hear that its to ensure one way transmission gulp! 4marks /cry =(
