Choose the correct answers from the alternatives given.
Which one of the following living phenomena is absent in viruses?

• A. Mutation
• B. Replication
• C. Production of energy
• D. None of these

Answer 1

Answer: (C)

Production of energy

C. Production of energy

Solution : Viruses are too small and too simple to produce energy. They do not have any physiological system to produce energy. If they have, they would be free living and would be considered as a complete living organism. They undergo replication and mutation more than any other organism.

So the correct answer is "Production of energy".
