Question

Explain antibiotic, resistance observed in bacteria in light of Darwinian selection theory.​

Answer 1

Answer:

Antibiotics prevent millions of deaths each year and remain the primary treatment for potentially fatal bacterial infections. Yet inappropriate prescription rates and overuse of antibiotics have led to resistance that has created a global health emergency and kills at least 700,000 people a year. If no action is taken, it is predicted to increase to 10 million deaths per year by 2050

Answer 2

Answer:

Darwinian selection theory states that individuals with favorable variations are better adapted than individuals with a less favorable variation.

An example of such selection is antibiotic resistance in bacteria.

When the bacterial population was grown on an agar plate containing antibiotic penicillin, the colonies that were sensitive to the penicillin died, whereas one or a few bacterial colonies that were resistant to penicillin survived.
