A research team is studying a population of snails to determine how quickly characteristic B will pass from one generation to the next. At the start of the study, 20% of the snails have characteristic B. After five generations, 81% of the population has characteristic B. Find
the percent of the population that will have characteristic B after eight generations. (Assume a = 2 and b = 1. Round your answer to the nearest whole number.)

Which of the following statements about the "greenbeard" effect is correct?
Richard Dawkins first hypothesized the existence of the "greenbeard" allele to explain why we observe some unusual phenotypes, such as green beard.
According to the hypothesis, the reason why the greenbeard phenotype is selected for is because the greenbeard individuals would preferentially receive altruistic benefit from non-greenbeard individuals.
The reason why the "greenbeard" hypothesis is possible is because when direct fitness and indirect fitness are in conflict, it is always the factors that increase the direct fitness that will triumph over the factors increasing the indirect fitness.
The "greenbeard" effect shows that it is possible to evolve altruistic behavior toward individuals who are not genetic kin.

Before Carl Woese, all cellular life forms were classified into five kingdoms: Monera, Fungi, Plants, Animals, and Protists. Using rRNA genes for phylogenetic reconstruction, Carl Woese uncovered a previously unrecognized group that was thought to be bacteria. Afterward, all cellular life forms were classified into three domains: Archaea, Bacteria, and Eucarya. It is found that the relationship among Archaea, Bacteria, and Eucarya changes, depending on which gene was used for phylogenetic reconstruction.
