Normal development, function and repair of the sensory epithelia in the inner ear are all dependent on proper cell junctions..Mutations in the connexin genes GJB2 and GJB6 disrupt the connections between adjacent cells in the epithelia of the cochlea. It is believed that disruption of these connections leads to a disruption of the proper flow of K ions from the cytoplasm of one cell to the cytoplasm of the next cell, leading to deafness. The disrupted junctions described above are.

A. plasmodesmata
B. adherens junctions
C. gap junctions
D. tight junctions

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?
