describe how Darwin's theory of evolution by natural selection can explain the spread of antibiotic-resistant microorganisms which caused the return of Latasha strep throat?

The correct answer is "Darwin's theory of evolution is based on the premise of survival of the fittest; antibiotic-resistant microorganisms are selected by overuse of antibiotics".

Explanation:

Darwin's theory of evolution states that advantageous traits in living beings are selected under the premise of survival of the fittest, where the living beings with the advantageous traits are more likely to survive and reproduce. Darwin's theory of evolution explains the spread of antibiotic-resistant microorganisms, because resistance to antibiotics is an advantageous trait for microorganisms that are constantly in contact with antibiotics. The irresponsibly use of antibiotics leads to the spread of antibiotic-resistant microorganisms, because microorganisms that are naturally resistant to antibiotics are constantly selected and can reproduce and prosper.
