Which of the answer choices correctly identifies the major mining, ranching, and farming regions of the west in the late 1800s? a - mining; b - farming; c -ranching a - ranching; b - farming; c - mining a - mining; b - ranching; c- farming

This would be the second option (A) mining, (B) farming, and (C) ranching. Mining tends to be geographically spread out as formations underground are scarce and difficult to come by, the area of ranching in the USA is typically dry which means that ranching is more likely in those dry areas, whereas farming is likely in area B as the land is more arable.

genetics is the study of how dna works, the methodologies defining the new recent technologies allow scientist to have a panoramic view of the entire dna landscape, especially how genomes interact with their environment, including off course, factors outside their organisms.

thus is very possible the existence of both scenarios, where populations of isolated individuals have different genetic traits, and share traits related to genetic mutation, due rats can easily travel overseas using human transport channels. so scientists could get a vast number of data, including human interaction, evolution of rodents, health development, spread of infections, development of new organisms, how genomes evolve in different environments and so on.
