This is a great quiz tallsaul - just a couple of suggestions, buffers and enzymes weren't accepted in their pural form despite the wording in the question.

A few things: 'Sugars' are perfectly acceptable carbohydrates. Carolus Linnaeus' name is also Carl von Linne. Mitosis is the name of the whole process: if you use the word 'stage,' you misdirect people to saying subdivisions (e.g. anaphase). No reason not to accept 'ATP.' Prokaryotes have DNA but no nucleus at all. 'Fixation' alone should count. 'Fermentation' also releases energy for a cell. Many plankton (like fish larvae) are heterotrophs: you should specify 'phytoplankton.' Mutations are not permanent; there are dedicated repair mechanisms.

@sufradley: Thanks, I'll fix that.

@cthulhu: a few things: you're being overly picky on a few of these things. I don't even know why you brought up 'sugars' as there are no questions where that would be an acceptable answer. By far, most people refer to Linnaeus as Linnaeus, though I did add your preference. The mitosis question isn't misleading because I was referring to which stage of the cell cycle, not cell division itself. Also, 'cell's nucleus and nuclear material divide' describes the whole of mitosis and not just one of the 4 parts within it. I DO accept ATP. I know perfectly well that prokaryotes have DNA and no nucleus (don't know why you're bringing it up). I added just fixation and also fermentation. I know about plankton, I also accepted algae, and now I accept phytoplankton. And mutations are permanent within the cell where they occur.

@tallsaul: I think you're misunderstanding me as more critical than I am, I liked the quiz. I said 'sugars' because you can change the last word of that clue from waxes (instead of the first one to 'lipids'), and this makes it just as true again. Thanks for taking my advice. We'll just have to disagree about mutations. I appreciate your consideration.

I agree with cthulhu on the mitosis one being somewhat confusing. I think of mitosis more as a process than a stage of the cell cycle. And using interphase does make it seem like you're looking for one of the phases of mitosis, even if the things mentioned don't both occur in any one phase. (which itself further adds to the confusion) Other than that, well done.

Yay! The biology degree paid off!

Good quiz! I got a bit lazy at the end though, though I'm not sure I'd get "carrying capacity" as I never had to study any ecology at degree level. Just a few criticisms: 1) The cell cycle question seems misleading to me - the stages of mitosis (prophase, anaphase etc) aren't the same thing as the full cell cycle (G1, S, G2 and M phases). Effectively interphase corresponds to the G1, S and G2 phases and the stages of mitosis are all in the M phase. So if you just state "interphase" without further elaborating then it implies to me that you are looking for a specific step in mitosis (presumably cytokinesis) rather than for mitosis/M phase itself. 2) Strictly speaking mutations aren't necessarily permanent, they're only permanent if they are retained after the cell divides. If the wrong nucleotide is incorporated by DNA polymerase by accident then this is definitely considered a mutation but is usually reversed before the cell divides again. It's a small niggle and probably not worth changing the questions over, but nevertheless, a mutation is not necessarily permanent. 3) If I'm going to be really pendantic there are more kinds of programmed cell death than apoptosis. I doubt anyone will be giving another correct answer to that question though, so this is really pendantry for pendantry's sake :P Despite these niggles, still a good quiz. Good to see some molecular biology and metabolism on here!
Jul 12th, 2011 at 10:16 GMT
Sorry - one more thing: "Mitochondria convert sugars into usable energy" - strictly speaking the mitochondria don't metabolise the sugars directly, the metabolism of glucose begins in the cytoplasm and even though the bulk of the ATP is generated later on at the mitochondria (if there's oxygen present). Again, probably not worth worrying about, it's just technically not 100% correct. Imo.

Good quiz, though I have two comments: First, regarding the DNA question, there are double-stranded RNAs (though they are mainly viral) and DNA is also found in mitochondria and chloroplasts, not solely in the nucleus. Second, the adaptation question is confusing to me because it could easily mean trait (or even allele or mutation).
