Help antimicrobial resistance is a broad term used to address any microorganism that has developed the ability to adapt and grow in the presence of a medication intended to prevent its growth? True or false explanation

Answers

Answer:

The statement is true, since antimicrobial resistance refers to the resistance developed —through mutation— by a bacterium to antibiotics, which adapt and grow in spite of the existence of the drug.

Explanation:

Antimicrobial resistance is due to the ability developed by some organisms —especially bacteria— to be unaffected by the presence of an antibiotic, intended to prevent their development and growth.

When a bacterium is exposed to an antibiotic, its organism develops -through successive mutations- mechanisms to prevent the action of the drug, a characteristic that will be transmitted to its descendants. Antimicrobial resistance serves as an example for evolution by natural selection, since resistant bacteria survive and those that have not mutated do not.
