In human genomes, the per nucleotide mutation rate is estimated to be about 2.5 x 10^-8. let us consider a recessive lethal genetic disease caused by a single point mutation. we will name the allele produced by this point mutation l, and the wild-type allele w. let us further assume that the disease phenotype expressed by ll individuals always kills those who have it before they reproduce. what would you predict the equilibrium frequency of the allele l be in the population after many generations? (you may assume hardy-weinberg equilibrium except for mutation and selection, and you may assume as an approximations that back-mutations from l to wild-type are rare enough to be ignored).

Match the type of adaptation to the correct example, structural adaptation functional adaptation behavioral adaptation example type of adaptation elephants live in herds to protect their young leaves of a rain forest plant species have a pointed tip that enables rainwater to drain off easily. camels have nostrils that they can close snakes produce venom to kill prey and defend themselves. earthworms coil when touched, as part of a defense mechanism. human skin darkens with increased exposure to sunlight.

Which of these statements are true about scientific theories and hypothesis

He did not infringe upon the policy making powers that he felt the constitution gave congress. but the determination of foreign policy became preponderantly a presidential concern. when the french revolution led to a major war between france and england, washington refused to accept entirely the recommendations of either his secretary of state thomas jefferson, who was pro-french, or his secretary of the treasury alexander hamilton, who was pro-british. rather, he insisted upon a neutral course until the united states could grow stronger. which provides the best objective summary of this excerpt? president washington made a good choice when he decided not to accept the recommendations of his advisors and instead insisted that the united states stay neutral during the war between france and england as president, washington believed that the united states should remain neutral in foreign policy even though he had advisors who recommended that he take sides during the war between france and england. washington did not make policy decisions during his presidency because he did not want to interfere with the policy-making powers that the constitution gave congress. washington refused to accept entirely the recommendations of either his secretary of state thomas jefferson, who was pro-french, or his secretary of the treasury alexander hamilton, who was pro-britis
