Solution
Answer
c. The wisespread use of antibiotics has led to resistant strains of viruses. - False.
Antibiotic resistance is the ability of a viruses to resist th effects of medication previously used to treat them. With each virus, some strains have become resistant to the administered drug. If only one antiviral drug is used thenthe resistant strains emerge rapidly, but using three or more drugs together has helped to control the emerging resitance. Therefore, not all viruses hads developed resistant strains after use of antibiotics.
