    No I did not do the paper,already did it in Jan 2013 and got an A, just curious if it was harder than our paper in Jan


    How was it for you

    Looking at peoples comment , the paper was nice
    It was pretty good but heavy on biodiversity which often brings boundaries down

    I didn't either but I don't think you had to actually specify. Although I think I may have put which ones were long term, just not the short terms ones
    So hopefully I'll still get some credit everything I said was right (I think) so howpfully just a couple deducted for not specifying

    nice than last june for sure

    yeah it was OK-dont think I've got full UMS as I was aiming for-didn't realise the last one was microscopic -__ - and wrote about allopatric/sympatric speciation and migration due to changes in climate LOL im so clever...
    then afew other ambigious bits here and there like the hydrogen bonding -completely forgot about 2-3 -_-
    think i should still have an A though

    I think its Mycobacterium tuberculosis and Mycobacterium bovis. That's what I put (Don't think you'll need both)
    Yeah I looked it up after the exam, it's only 1 mark so it's not the end of the world

    You still should have got it right as both a real bear and the bug are eukaryotic and animals
    Oh yeah nevermind, woo! I spent ages at the end trying to find the question that used the second picture.

    I think I lost one or two marks on that, I realised last minute that the "water bear" was actually that microscopic organism on the insert...not an actual bear, silly me.
    Not an actual bear lmaoooo that has made my day!

    Would I lose a mark for putting just Mycobacterium? Also, for the dehydrogenase question, I talked about the actual mechanism rather than active site, etc. Would I get any marks?

    I put animalia and Eukaryotae

    Am I safe in assuming the boundary for an A will be 72 or less?

    I expect we'll need acess to the paper first, so it may be a little while yet!

    Because of how pedantic OCR are I would be inclined to say you would drop the mark for only Mycobacterium

    wasnt it just that TB is a droplet infection so the disease spreads in droplets in coughs/sneezes etc

    You must write Mycobacterium tuberuclosis underlined.

    I put droplet infection - the bacterium is present in droplets in the saliva so when an individual coughs/speaks, the droplets leave their mouth and pass into another person?
