points dna inside living cells becomes charged as each base pair steals a pair of electrons from surrounding water molecules and releases a pair of hydrogen ions (a) do some research and determine the typical number of base pairs in a human chromosome (not the number in the y your answer should includea reference to the source or sources used in your answer. (3 points) (b) estimate the electric force between two typical chromosomes assuming that they are held one micrometer apart in vacuum. assume that the two chromosomes are coiled up and can be treated as point charges, each with a charge of 2 extra electrons per base pair. (5 points) (c) in a living cell dna is surrounded by water that contains both negatively and positively charged ions that are free to move (since water is a conductor). how do you think these ions will respond to the presence of a charged chromosome? (2 points)

22. the top of a cliff is located a distance h above the ground. at a distance h/2 there is a branch that juts out from the side of the cliff, and on this branch a bird's nest is located. two children throw stones at the nest with the same initial speed, one stone straight downward from the top of the cliff and the other stone straight upward from the ground. in the absence of air resistance, which stone hits the nest in the least amount of time?
