As a cell grows, the surface area to volume (sa: v) decreases and the cell must divide or die. the decreased sa: v ratio decreases would affect all but a) osmosis into and out of the cell. eliminate b) the efficiency of signaling proteins. c) the number of stages involved in cell division. d) the functioning of the cytoskeleton transport system.

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.
