How did the Dred Scott Decision divide the country

In 1846, Dred Scott, a slave living in St. Louis, sued in a Missouri court for his and his family’s freedom

Explanation:

Eleven years later, the case reached the highest federal court in Dred Scott v. Sandford, where the U.S. Supreme Court rejected Scott’s claim to freedom by a vote of 7-2. While the verdict had a personal impact on Scott and his family, it also had legal, political, social, and economic ramifications that reverberated throughout the country in the years immediately preceding the Civil War.

employers subject to title vii are prohibited from taking race or sex into account in any employment decisions. aa is a penalty for having any job group substantially statistically "underutilized" in any race or either sex. the employer must take steps to eliminate the underutilization, then stop, ending its aa efforts

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.
