    Do you think that the biological importance of water is a realistic essay title, I mean there isn't that much on it - is there?

    Ammonification and nitrogen fixation produce NH4+ (ammonium)
    Nitrification produces NO2- (nitrites) which are then oxidised to NO3- (nitrates) for absorption

    Don't forget plants can absorb ammonium ions too - and use these to join with glucose derivatives to form amino acids directly. These ammonium ions can be made in root nodules during nitrogen fixation, and plants can absorb them directly. Plants can absorb nitrates from soil too of course....

    Hey, can someone tell me if this is correct? thanks

    FSH = Stimulates follicle development (Technically stimulates oestrogen)
    LH = Stimulates ovulation
    Oestrogen = Stimulates uterus lining to thicken (Also inhibits FSH)
    Progesterone = Maintains think uterus lining (also inhibits FSH)

    There's loads you can write on water.

    Cohesion tension

    Transpiration

    Evaporation and heat regulation

    Photolysis of water

    Transport of substances - mass transport, xylem, phloem, blood

    Osmoregulation

    Hydrolysis

    Support / turgidity

    Cell transport

    Oestrogen at low concentration inhibits FSH (and LH). At high concentrations it stimulates LH (and less importantly FSH too weirdly).

    Progesterone inhibits FSH and LH.

    I've seen mass transport in a few mark schemes but i have no idea what it is. Could u explain plz?

    Mass transport is the bulk movement of substances around an organism using the flow of the fluid in which the substances are, rather than diffusion. Thus blood mass transports things like dissolved glucose within the water, and the xylem mass transports ions dissolved in water.

    A little bit like a river carrying all the things dissolved in it.

    It's much faster than diffusion, especially over long distances

    Guys how many marks are allocated for out of spec info? If you were to get all the A-level biology content in can you still get a decent mark?

    Extra content only counts in the essay.

    Without any extra content your maximum marks are S - 12, B - 3, Q - 3 and R - 3 = 21/25.

    For each significant piece of material off syllabus in your essay (i.e. a few sentences or so) you will gain plus 2 marks for your S mark taking you to 23/25 or for significant extra content 25/25 (assuming your breadth, relevance and quality of communication are first-rate of course). However, extra information does not count if your essay contains fundamental errors or if it is ranked as an average essay (S mark of 8) or lower; in this case extra content does not count.

    Your essay needs to be good (S mark of 12) before extra content can essentially score.

    Thanks, so I might aim for the most basic essay (Assuming you have all the detail and the 3 other factors are first class) without any of the spec stuff as I have a full book of extra stuff but didn't really have time to learn it due to other exams and don't think I can learn much now
