If dichloromethane is swapped out and ethyl acetate is used in its place, the extracts then obtained would be highly anti-radical and would be more efficient than dichloromethane.
Since "like dissolves like," ethyl acetate is a polar molecule that works well as a solvent to extract the polar caffeine molecules from coffee beans. The ethyl acetate molecules bind to the caffeine molecules, which then move through the bean cells' cell membranes. After all, the ethanol:water (1:1) solvent combination has been demonstrated to be the best for recovering catechins and delivering extracts with the highest antiradical activity.
Dichloromethane is a volatile colourless liquid used as an organic solvent in many industries. One of its main application is that it used to extract caffeine because of its highly effective solvent nature. Because DCM is a non-polar solvent and caffeine is readily soluble in DCM, it can easily be extracted without losing its aroma.

I think the right answer would be intercultural
<span>The narrator
has such a large number of contending driving forces in his mind: to accomplish
exact retribution on Dr. Bledsoe, to advance in Harlem, and to satisfy the
desires of his friends and family. In any case, he seethes under the impacts of
"self control, </span>that frozen virtue, that freezing vice.” The irony is self-evident, alluding
to what is ordinarily viewed as a discipline as both bad habit and virtue, as
one that deadens as opposed to solidifies.
Answer:
Tragedy of the Commons.
Explanation:
While people throwing cigarette butts led environmental degradation because of the plastic material of the butts and other chemicals they absorb. It is a classic example of Tragedy of Commons which means that an individual is motivated by self-interest to perform actions that are contradictory to well-being others or the environment shared by others.
