    Does anyone know the answer to the question that was like 'name the process by which plants remove salt?'
    I'm fairly sure it was just 'active transport'

    I said active transport and then said how the mitochondrion shows aerobic respiration occurs which provides an abundance of ATP which allows active transport to occur as it's an energy requiring process...

    I put active transport but then i got confused on the next bit when it started asking about mitochondria. the first question of section b was easy though

    What the actual f**k was the meiosis question with the 'fill in the homologous chromosomes', I just put R's a B's on random bits, should have just left it blank. Essays were good, but for the first one - photosynthetic pigments and light dependent stage - how can you get 6 marks for describing water splitting? Was restraining myself from just writing out the calvin cycle as well.

    I said because the sub-populations were unable to freely interbreed to produce fertile offspring...complete guess though!

    Breeds to produce infertile offspring or cannot breed, I think.

    I just said that the groups had been separated to different parts of the island which would have different enviroments and therefore different selective pressures.

    Ah, I think I got that one! When they interbreed they will not produce fertile young as there are now to different gene pools

    For the question about hummingbirds and why they have a higher body mass in summer I was like there is more nectar... then I said produced by bees instead of flowers hahah idiot :[

    Think the mitochondria bit was to allow extensive respiration, so that there is enough ATP to absorb all the salty water against the gradient.

    Think it was so that they have enough body mass to survive migration, where they might not have a chance to feed regularly.

    I put something like 'they'd be unable to breed to produce fertile offspring' pretty sure it's right!

    Bigger bidy mass in summer as there is increased food availability. simple as that.

    Might be that but they migrate in Spring as well after Winter (well obviously) and in Winter they had a really low body mass? Idk I've completely messed up that question.

    P.s. see if you didn't write "root hair cell" but then you wrote large surface area for the cell thing you wrote, would you get the mark?

    I said higher temperature so more prey? so more food so increased mass. Or something like that.
