    Density dependent factors.... Availability of food source... space... accumulation of toxic waste etc...
    I know but 'describe' implies a more detailed response than just simply stating the factors?

    What are two forms of nitrogen taken up by plants? I put nitrates and ammonium.
    As someone has already said WJEC insist on asking questions from little obscure parts of the syllabus and avoid whole topics.

    I said ammonium ions & atmospheric nitrogen because Rhizobium is found in roots of legumes :confused:

    why did you have to multiply it by 2? I think I got 680000. Is that wrong then? Damn!

    What about that put the numbers in the table respiration question near the end? Substrate phosphorylation and ATP used in phosphorylation? Never head of the first and thought phosphorylation was making ATP...

    Yeah explain as well! Intraspecific comp for food... Can't get nutrients they require.... Toxic waste makes disease and infection more likely...

    Cheers. Fair enough, I remember the graph showing that actually. So sneaky though, that's really knocked my confidence

    I think but I have absolutely no idea, thinking now that the three was wrong and it should have been 2. Phosphorylation is just the addition of a phosphate group so one for the conversion of glucose to hexose phosphate should be right I think!

    Substrate level Phosp. happens in Glycolysis twice and in Kreb's however there was no label in Kreb's that matched where Phos. occurs so it was just 1 and 2.
    It was between 3 and 4 for the second box.
    Last box was almost certainly just 1.

    Ah damn I thought it happened in the link reaction as well but thinking about it that doesn't really make sense... Should have put two in the top one... oh well what's done is done.

    Q1
    -Photoperiodism
    -Phytochrome
    -Leaf
    -Nitrates/Nitrites/Ammonium (?)
    -Denitrification
    -Azotobacter

    Q2
    -G+ Purple and G- Red
    -Gram positive have just murein cell wall so take up Violet, negative have lipopolysaccaride layer as well as murein so do not take up die, however once treated with Iodine they take up Counter stain.
    -Bacillus
    -Spirillus
    -Coccus
    -Something about lipopolysaccaride layer protecting from stomach acid maybe?
    -Three of the plates had too many colonies so clumped together, the other had too little.
    -1 690 000
    -Some colonies may merge together so are only counted as one.

    Anybody who wishes to add any other answers I'll happily put them together.

    I thought it was between 1 and 2 for the second box. Because Glycerol would enter Glycolysis as a 3 Carbon molecule equivalent to Triose Phosphate, which was in between 1 and 2. Although I could be wrong, and I probably am.

    I have literally no idea either I just guessed. I think you may be right come to think of it.

    This is the exam thread, if you don't want to discuss the exam that's fine but I would advise against reading this thread.

    I'm aware what this thread is. I made it. If people want to know the answers to the paper, I'm sure they can ask you instead of you posting it for the whole student world to see.

    There was a label in kerbs where it occurs wasn't there? Between the 5C and the 4C.... I could be wrong though aha

    Then what is this thread for exactly? Exam threads are for discussing the paper after the exam, just look at the AQA and OCR Biology exam threads.

    Well, if you scroll back the past 7 pages to the start I'm sure you'll read what the thread was for. I think you'll find that it wasn't for answers to the exam, purely for discussing the possible topic that may be involved.
