You are swimming in Lake Lanier with your friends. You are trying to see who can stay underwater the longest. You stayed under for 48 seconds! When you come up for air, you take a big breath. Your cells need oxygen so they can release energy so you can keep swimming. Explain all the parts of the cell involved in getting oxygen into your cells so it can help release energy and draw a picture of what is happening in the cell.

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.
