Akey difference between green algae and land-based plants is that a. land-based plants don't have vascular tissue and must absorb nutrients directly from the environment. b. green algae don't have chloroplasts and absorb their food rather that perform photosynthesis. c. green algae don't have vascular tissue and must absorb nutrients directly from the environment. d. land-based plants breath in carbon dioxide while green algae consume oxygen.

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.
