Mutations are like genetic mutations. Say a bird species may usually have a orange beak but one bird was born with blue, that’s a mutation.
Adaptations are things you adapt to like plant species have adapted over the year to receive less and less water to live.
Natural selection is basically ‘killing off’ the weaker ones. Say a bird species has broad wings but mutations happened over time leading them to have small wings that do not allow flight, they may eventually all die off due to that. Extinction is if al those birds were to die off from that mutation.

Answer:

Sample Response: Adaptations result from random mutations in the genes of organisms. Depending on the environment, these adaptations may be favorable or unfavorable. If an adaptation is favorable, it is selected by nature and, over time, more and more organisms in a population will have it. If the environment changes so much that the adaptations of a species are no longer enough for the species to survive, extinction will occur.

Blacks "live within two concentric circles of segregation" means
mr_godi [17]
<span>King stated this, he believed that black people were located at the bottom of the economic ladder. Their two circles of segregation were one that kept them prisoner based on their skin color while the other held them prisoner in poverty and deprivation. The average black person struggles to escape his circumstances but is hindered by these factors. He receives no normal education and no normal social or economic opportunities. When he attempts to try to better himself, he is told to lift himself up on his own by bis bootstraps, advice that is senseless considering he is often barefoot.</span>
