    Thought it was pretty tough. It deviated from the theory side for me, and went towards the application side. Should be around 60-65 when it comes to these papers.

    physics paper 3, harder than hard

    I thought the efficiency was somewhere around 25% since it's useful energy/total energy yes?

    Nitrogen cycle, selective breeding,mircrovilli, question on mammals, experiments on tomato seedlings

    The heart came out, but not the lung if I'm not mistaken.

    By the way, how did you all define growth? I said: The permanent increase in dry mass of an organism by an increase in cell number or cell size or both. Is that okay?

    Sorry, didn't read. Well, probably drugs, nervous system, pollution, plant reproduction.

    Nitrogen cycle, selective breeding,mircrovilli, question on mammals, experiments on tomato seedlings

    I don't think it's microvilli, since microvilli is on the villi, and that was an epithelium cell. So it should be a villi, but its functions are similar though. (increase surface area)

    You're using amino acids and converting into your own protein. The liver is involved in protein synthesis, and the liver is involved in assimilation. So I think it would be accepted.

    Thanks Justine! Now that you all mention the cilia/villi thing, I keep thinking I wrote cilia, when I'm sure I wrote villi! I definitely got the adaptations right though. :P I put anabolism. Don't think it's in the syllabus though.

    For the selective breeding/genetic breeding question, I just wrote that one was selectively breeded and one was genetically engineered. I think I'll only get one mark or none at all ;_;

    PHYSICS 31 doubts plzzz clear :P

    Last link, Q11 - Same thing, nucleon numbers - proton + neutron. Though nucleon number may change, proton number WILL always stay the SAME! Any practical use, such as gas leakage detectors and cancer treatment and paper thickness control. Q7- a) For the mirror, it reflects. For the glass...

    PHYSICS 31 doubts plzzz clear :P

    For the second link, since there's no aiii, i'm assuming you mean b(iii). Well, it's pretty simple. Due to the formula p1v1=p2v2, we can say that it applies for the bubble as well. So at the bottom, the bubble has a specific volume, and there is a specific pressure at the bottom of the pool...

    PHYSICS 31 doubts plzzz clear :P

    For the first link, it's effiency is 10%. Therefore you calculate the total energy it produces, and divide it by 10. Since the previous figure in 5(a)(i) is in 1 second, there is no need to divide the answer by time. (actually there is, but anything divided by 1 is the same) For part (b), I...

    So you expect them to give us an odd flower, one which they do NOT give in their books? Plus, they teach us the same thing either way. It's fact.
