Celia is staring at the clock waiting for school to end so that she can go to track practice. she notices that the 4-inch-long minute hand is rotating around the clock and marking off time like degrees on a unit circle.
part 1: how many radians does the minute hand move from 1: 25 to 1: 50? (hint: find the number of degrees per minute first.)

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.
