    why was the dose given per unit mass per unit time? :/
    Allows comparison between volunteers of different mass and treatment length.

    guys, what did you put for the cell cycle/intestine lining question?
    Easily repaired cell apparently. But i just said
    faster mitosis, so faster Growth 1 (organelles - proteins - needed for it), synthesis, and then growth 2. I hope there's a broader markscheme (but with aqa, unfortunately not)

    It is very unlikely that it'll be 60+ for an A. So I hope i've scraped it!

    Antibiotics kill the non resistant bacteria
    The resistant bacteria then grow in population
    They contain a plasmid for survival
    They pass the plasmid through horizontal transmission
    Via conjugation
