3. Warfarin is a poison that is used to kill rodents. Resistance to this poison is a genetically determined trait in rats. Homozygotes carrying the resistance allele (WRWR) have a lower fitness because they suffer from vitamin K deficiency, but heterozygotes (WRWS) do not have this deficiency. Even so, the heterozygotes are resistant to warfarin. In an area where warfarin is used, a heterozygote has a survival advantage. Due to warfarin resistance, a heterozygote is also more fit than a homozygote (WSWS) that is sensitive to warfarin. If the relative fitness values for WRWS, WRWR, and WSWS individuals are 1.0, 0.37, and 0.19, respectively, in areas where warfarin is applied, calculate the allele frequencies at equilibrium. How would this equilibrium be affected if the rats were no longer exposed to warfarin

African penguins, which inhabit the coasts of southern africa, were classified as an endangered species in 2010. two significant threats to their survival are ecosystem damage from oil spills and overfishing by humans. overfishing depletes the food supply of african penguins. the best method to reduce the threat of overfishing would be to . the risk of oil spills could be reduced by increasing the use of , which should oil consumption. if an oil spill does occur, could be used to remove the oil so the ecosystem may more quickly recover.
