Human digestion - 1. Rank the test tubes in order of greatest amount of digestion to least amount of digestion. For each tube, explain why it would have exhibited that level of digestion.
2. How could the experiment be modified to further test human digestion actions? What variables would you change? What would you keep the same?
3.In which test tube was the activity most like that of a real human stomach? Explain.

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.
