    Water bear I put animalia purely because it was multicellular.

    My mind went blank on collagen structure ffs. Then I put virus for the TB transmitter..... But other than that it was amazing when compared to F211. Unfortunately I think I'll probably lose about 20 marks because the markscheme is so bloody picky and precise even if you have the right idea.

    Protocrista due to size (0.1 micro meters) and it being a water bear

    Protoctusta are usually found in water
    In the question it said it was an invertabrate, meaning it had to be animal

    why the grey squirrel populus may be lower than the red squirrel even though the sampling of people says the opposite?

    I put:
    Red squirrels only come out at night, people not around at night.
    Grey squirrels may be counted twice by two different people.

    Just give people who think they're not animals this link: http://en.wikipedia.org/wiki/Tardigrade

    First line is particularly interesting, "Tardigrades (commonly known as waterbears or moss piglets)[2] are small, water-dwelling, segmented animals with eight legs."

    Grey squirrels may be counted twice by two different people.

    I put because grey squirrels are in plain sight more often since they are mostly on the ground. Then I also put they may have counted some squirrels twice.

    I don't think red squirrels come out at night...Squirrels aren't nocturnal.

    It wasn't an inhibitor as it was also broken down by the enzyme
    This. It reduces conc. of toxic products in liver by mixing with non toxic from ethanol and also less DHG in wine to begin so effects are less s there is less of the toxin

    Last question - just followed the sequence - think I put order as one of the things though

    That confused me too...I settled with putting protein lol, probably wrong but only 1 mark
    I noticed they had protein in the question, so it was between polypeptide and enzyme. I just put enzyme.

    3 easy marks ffs
    Join the club. I completely BOMBED out on these 3 easy marks.
    I could probably get a PhD in enzyme-substrate stuff xD But the pressure of the exam hall completely threw me. SUCH easy marks but the context was dodgy for me.

    I put that they were only reported from some areas as the question hinted that they were reported from a few areas, suggesting that not everywhere has been reported from, so there could be less than they think. Something along those lines, not word for word though
