A 150-nucleotide sequence of DNA from humans and five other vertebrates were analyzed, with the following results: Species A had 29 nucleotides that differed from the human DNA. Species B had 85 nucleotides that differed from human DNA. Species C had 5 nucleotides that differed from human DNA. Species D had 92 nucleotides that differed from the human DNA. Species E had 37 nucleotides that differed from human DNA. Which species is most distantly related to humans

Humans are believed to have evolved in coastal regions in east africa. the region had an abundant supply of fish for early humanoids to eat. when scientists analyze the fads gene they see an interesting pattern. people whose families have lived in this area of east africa for generation show a high level of diversity in alleles for the fads gene. conversely, people whose families had migrated inland a moderate distance from sources of fish showed a much lower diversity for fads gene alleles. additionally, the fads alleles found in people whose family has lived inland for generation are almost all gene alleles which produce fads proteins with a high level of function and activity. how do anthropologists explain this?

Anne, an intern in a microbiology lab, was observing the characteristics of various specimens of protists. match each specimen to the category of protist to which it belongs.

In 2001, records showed that local stocks of fish were down worldwide. yet, records of harvests indicated that fish were being taken at records rates. what was actually happening?
