    Yeah I thought that none of them overlapped as I added the standard deviations to the mean values... Is this wrong?
    That's what I did. I added the SD to the mean

    You also need to subtract.
    Yeah I subtracted as well but I didn't get any overlaps unless I made a mistake

    what did people put for how to find out the mean number of mitochondria in that leaf thing or something like that
    I wrote it out in words but because I had so much stuff crossed out I decided to write it out like an equation under the wordy bit.
    The equation was basically-
    (Total cross-sectional area of the leaf)/(Cross-sectional area of the temporary mount) x (mean number of chloroplasts in mesophyll cells per temporary mount I wrote about taking a few temporary mounts samples and finding the mean number of chloroplasts in the wordy bit ) = (mean number of chloroplasts in mesophyll cells of a leaf)

    Also a question about positives about having anaemic blood?
    I said stuff along the lines of oxygen more readily dissociates to the muscles than healthy blood.
    After for 4 pKa (from graph), anaemic blood more readily binds to O^2 than healthy blood.
    Can continue to quite readily bind with O^2 after 12kPa more so than healthy blood which plateaus...
    Anything else???
    I think it was just a simple haemoglobin question as it asked about the advantages:

    Haemoglobin has a higher affinity for oxygen in anaemic people
    Haemoglobin readily dissociates/unloads from oxygen at the respiring tissues
    For more respiration

    i Worte ther is no significant difference between the number of chickens with resistance bacteria and the number of what ever the other animal was

    and there is no significant difference between the number of chicken farmers with resistanct bacteria and the number of chicken farmers
    Wouldn't those be null hypotheses though?

    Ugh.. wasn't it to do with selective breading, which was why the genetic diversity was lower than the other bull terrier?
    The question said that the species of dog had a lower genetic diversity and it descended from the Bull terrier... or something along those lines anyways...

    I said split the temporary mount into grids of equal area
    Count the number of chloroplasts per area squared from a sample of these (e.g 10)
    Times the number of chloroplasts per area squared by the total number of grids

    I had no idea.

    hmm that makes more sense, think i read the question wrong and answered it thinking it was something like:

    why are they different
