    can you remind me of the enzyme question? my minds gone blank I can't remember it =/

    Those questions were so good!! And the last question was nice as well!!

    What did you write for the last question about changes in phenotype being too slow? I spoke about allele frequency and evolution =/

    What did you write for the carbon neutral question?
    The second bit was about greenhouse gas and radiating the long wave that the earth radiates out after absorbing.

    The first bit was energy used to cut the forest. If those trees have been there a long time then the carbon was trapped a while ago. And once the biofuels are in use it still takes machinery and transport.

    What about why measure the KJ over a year and not just the mass on one day for the NPP? I think I rambled on a bit there...

    Something about how the enzyme will cause cell lysis wasn't it. But was it our enzyme or the bacteria's enzyme - can't remember.

    I thought that was an odd exam really, it seemed to almost have a lot of topic 3 things in it, especially with the second question in about how a single cell divides into a group of genetically identical cells. I felt like with that question it wanted us to go into detail with mitosis, but then it was only 3 marks... There were some nice 'easy' questions though, like picking the 4 biofuels and naming the bases. Also, what did any of you put for the multiple choice question about whether light intensity and moisture content affected the distribution of that unicellular organism?

    I put both. The first choice I think. There didn't seem to be much evidence that one was a much more significant factor...

    I agree, when I read the question about naming the bases I was like " lol what .. :eek:?" The exam wasn't hard but I tought that there were some tough/unfamiliar questions. I struggelled with the timing in the first few questions but I eventually managed to finish it on time tough.

    It was about the enzyme that was made from the virus and how it caused lysis to the cell membrane I think, it was quite confusing

    Yeah, I did the same.

    That was well weird, NO DATA ANALYSIS :O

    Tiny little bit on global warming, no tree rings, peat bog etc

    No succession as well omg

    Got a feeling a made daft mistakes though :/

    I put Cystine instead of Cytosine lawl. :|

    Was it how the enzyme broke down the cell membrane?
    I said, the enzyme is specific, and acts on cholesterol molecules in the membrane. I said that the cholesterol gives rigidity to the membrane, and when they are broken down by the enzyme, the membrane would rupture easily. Dunno if that's right

    I thunk it was about the selection pressures being the same for both as they both occupy similiar niches etc...

    That sounds like a pretty good answer, it was just suggest so I'm hoping if we talked about any part of the cell membrane we will get the mark, I started rambling on about the phospholipid bi layer!

    I BS that one. Put something about it takes a mean for the year as the energy available changes with seasons.
    What did people put for the investigation to see what affect light had on the organism?

    I put about skin being impenetrable, and that the skin was made of Keratin.
    It formed a tough barrier.

    No idea if it is right though.

    I said that too.
    I also mentioned that maybe the pH of the skin causes the protein coat to deform, hence the virus becomes inactive?
