Modern cetaceans, the taxonomic group that includes whales, dolphins, and porpoises, evolved from land mammals. however, it has only been within the past few decades that transitional fossils have been found that have shed light on cetacean hindlimb reduction. dna data suggest that cetaceans are most closely related to hippos, which are even-toed ungulates. other even-toed ungulates include deer, pigs, camels, and cows. which statement describes most accurately how the early cetacean, pakicetus, fossil ankle bones shown in the figure supports the hypothesis that cetaceans are closely related to even-toed ungulates?

How does this experiment explain why it is often milder in areas such as coastal maryland while areas such as kansas or iowa have more extremes in temperature

In 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? in 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? staphylococcus aureus bacteria that were able to synthesize cell walls using a protein that was not affected by methicillin survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, some bacteria began to synthesize cell walls using a protein that was not affected by methicillin. these bacteria survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, bacterial populations gradually began to synthesize cell walls using a protein that was not affected by methicillin.

Which of the following statements is accurate about evolution? question 10 options: natural selection only eliminates odd individuals. evolution means that a population never has changes in its genetic frequencies. mutations are always harmful. evolution means that a population undergoes changes in its gene frequencies over time.
