Question

Excess, unnecessary or incomplete dosage of antibiotics may lead to:

• A. resistance of bacteria against that antibiotic
• B. increased immunity
• C. increase in efficiency of blood
• D. all of these

Answer 1

The correct option is A resistance of bacteria against that antibiotic

Bacteria evolve with respect to their outside environment. Antibiotics are chemicals that kill bacteria or slow down their growth. If bacteria are exposed to an antibiotic, the surviving population begins to develop immunity against the antibiotic. This immunity is passed on to successive generations and after few generations, the antibiotic eventually becomes ineffective.
