    What did everyone write about the krill further increasing global warming? I wrote some garbage about them migrating to a colder area where their waste will be decomposed
    Bro i just wrote that the condtions will change for the decomposers and they will die out, resulting in a build up of waste which can kill many species of the aquatic eco system

    I said that as sea temperatures increase, then saprotrophs etc will be able to decompose the faeces and therefore release the carbon dioxide from it back into the atmosphere which would then contribute to global warmimg! - can anyone verify this?
    I also put that the increase in sea temp. would mean the faeces could be decomposed which would release more carbon dioxide which would contribute to global warming.

    Did anyone mention the Siri equation as an answer to a question in PHE?

    What was the impedence one? I just blagged and wrote that its not accurate and there lean tissue such as muscle may be included LOL!

    Aww me too, i put weight and volume of water!

    Yeah i wrote "Excercising decreases weight!" hahaha
    I wrote it keeps you fit

    Why am i such an idiot! I read 2 QUESTIONS WRONG ASKFHAUFGB FML

    Could i answer that with the body masss of the indevidual plus the density of fat

    For the densitometry question I wrote the two measurements you need is the mass of the individual and the mass of water/air displaced. I take it that's wrong?

    Welll i was going to write that! But something made me think that you needed to know the mass of fat but im starting to doubt myself?

    What was question 13 again? The recombinant DNA one? Because that was either C or A technically it could have been either, because it's recombinant DNA with respect to both the Agrobacterium.t and the rhizobium DNA… all in all an evil question..

    What was the role of hydrogen bonding in maintaining the hairpin shape? I wrote an essay for it saying they have a function of providing support for the shape and talked about hydrogen bonding between base pairs

    It was mass and volume of water

    I'm pretty sure q8 is C because if 24/80 are thymine. This means 30% are T and 30% are A so 20% are C and G.
    An q14 is C because you need to 100+67=167kj
    And I think the rest are correct.
    I think for q14, the 100kJ is available to the ecosystem, as faeces - because it flows through the saprotrophic food chain. So it's on 67kJ, so A

    did anay one else right for the fuction of hydrogen bonding for the hairpin shape that the some bases are complimentary and for hyrgen bonding thus hole the strand together but the bases at the end are not thus their repulsion gives the ringed structure on the left and the lines pushing outwards = hairpin shape

    I agree for q14 lets hope the markers have the saprotrophic food chain in mind
