[RM.03]Uranium can supply energy for the world's electricity without emitting harmful greenhouse gases. Which of these statements best describes an outcome of uranium mining? The people living near the mines may suffer from diseases due to radiation.
The rivers and streams around the mines may become dry due to greater evaporation.
The regions near the mines get abundant electricity due to greater production of electricity.
The atmosphere around the mines remain unpolluted due to lesser amount of greenhouse gases.

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?
