Calculate the sedimentation coefficient in water for (a) A spherical cell of 3 µm radius. (b) A spherical (or globular) macromolecule of 3 nm radius. Assume that the density of each is 1.05 g/cm3. (c) Calculate the number of g’s required in a centrifuge if the cells are to be sedimented through 2 cm in 5 min. (d) Similarly, calculate the number of g’s required to sediment the macromolecule at a rate of 1 mm/h

14) whenever diploid populations are in hardy-weinberg equilibrium at a particular locus a) the allele's frequency should not change from one generation to the next, but its representation in homozygous and heterozygous genotypes may change. b) natural selection, gene flow, and genetic drift are acting equally to change an allele's frequency. c) this means that, at this locus, two alleles are present in equal proportions. d) the population itself is not evolving, but individuals within the population may be evolving.
