    convergence and divergence refers to the number of synapse a neurone makes......so its a different concept to summation

    you could be right, i'm just going off the green book...

    'this means that even if the generator potential from an individual receptor cell is insufficient to set up a synapse, the potentials from several may add together or summate to trigger an action potential. this is known as convergence.' pg 212.

    well it does say underneath how they may cause responses via interaction with proteins to act or activate transcription factors.............so if they do ask it would just be rephrasing how transcription factors cause gene expression

    it doesn't, its the sympathetic nerve connecting the brain to the SAN so only heart rates affected

    ok so from a spirometer trace you can get the vital capacity and the tidal volume which are about how much air you breath in and out so why is the soda lime cannister there because surely that would remove carbon dioxide

    tidal volume is how much we breath in and out, the CO2 needs to be removed as it would eventual be all the person takes in....and after all you want to look at how much oxygen is taken in so CO2 is not needed

    that's the point, it ensures you're only breathing in pure oxygen and that any co2 you breathe out is absorbed, otherwise your tidal volume would decrease because you'd end up breathing in large amounts of co2.

    Re phytochromes, do we need to know which one stimulates flowering/germination?

    if so..which ones do what?
