    I put nitrates and ammonia and then '(ions)' hahaha! what did anyone put for the 2 density dependent and 1 density independent factor?
    Density dependent: availability of food source, accumulation of toxic waste
    Density independent: temperature

    I did the osmoregulation one! Didn't feel like I had enough to write about the Calvin cycle essay :s
    Yeah same here! I don't really like photosynthesis haha Did you write about what happens (like ultrafiltration and selective reabsorption) and the negative feedback bit with the ADH and stuff..? I think I babbled on a bit much 'cause I ended up filling the three pages D:

    I think nitrates and ammonium ions is correct, I googled it (curiosity killed the cat) and saw that answer a few times for density dependent I wrote about toxic waste and depletion of nutrients but I was thrown by the density independent so just wrote an increase in temperature which could denature enzymes :s

    I wrote the definition then wrote about selective reabsorption and ADH! At least if you've written about all of it you are more likely to get all the marks haha

    I calculated it in the exam can't remember it now though! As long as I get an A/ A* I'd be happy (applied to do bio at uni so need a good grade )

    What about you?
