    I got 98.5% too
    It can't be 98.5% because going from 0.3 to 20.1 you would do change/initial X 100 which would be 19.8/0.3 X 100 giving you 6600

    I said exactly the same. Not sure if it's right too!

    Great 😫😂 Maybe I'll get a method mark? 😂

    For the % change question i got 6600% at first BUT I read the question again and i'm sure it said 'calculate % change from BLOOD to PLASMA' i.e (0.3-20.1/20.1 x 100) so i did that and got (-) 98.5%

    Was plasma 0.3 and blood 20.1?
    It didn't say percentage change though, it said percentage increase. How is going from 20.1 to 0.3 an increase?

    Hi, for the Polynucleotide chains it asked in DNA. So, I think you should've also included in a double helix, that are anti-parallel to each other. But I also put the hydrogen bonds between the bases

    It didn't ask for the structure of DNA, just about how it was bonded so I don't think you would have needed to put about the double helix but I'm not 100%

    For the percentage increase, it surely is 19.8% increase because the sample was out of 100cm^3 which cancels out with the 100%?? Am I right or nah

    I remember some of the multiple choice questions and have checked to make sure they are correct.

    The primary defence was D - blood clotting

    The 3 domains was A - Archaea, Bacteria and Eukaryota

    An organelle that is present in both eukaryotic and prokaryotic cells - Ribosomes (think it was C but not sure?)

    Not sure if this is right but I put - high low low low for the fluid pressure question.

    Not sure about the mitosis image either - I think I put metaphase??

    I got 0.63 (not sure if the last digit is correct) for the chromatography question.

    I said mineral ions are actively pumped in to the root hair to lower the water potential( so it has an even lower water potential than the soil), and as a result, water would move from the soil into the root hair from high to low water potential, not sure if it's right tho
    That's definitely right!

    for the multiple choice question, was the ventricular systole when the pressure went up or when it went down?

    I put that the zoos could raise money and awareness for the rhinos and then maybe they could use the money to keep an eye on the rhinos and give them medical support if they need it.
    Potentially. For some reason I put that they could research into them a bit more hence resulting in greater understanding of their needs for survival and that.

    Hmm I put anaphase... probably was metaphase though
    The chromosomes in the diagram were lined up at the centre, therefore the answer was metaphase.

    I put when it went up because systole is contraction

    the one for percentage increase was 98.05% i think. bonding of two nucleotides was condensation reaction, obviously water given out. the multiple choice question about potometers, was that the tap didn't need to be open, the table for the rhino was something like, animalia, phylum, class, genus and sumatrasomething cant remember. Would i be correct if i put permanent Vacuole instead of tonoplast?
    thats what i got too
