Q1. A virus is inert outside a host. Is it living or non-living? Justify.
Ans: Virus is non-living outside as it cannot metabolize or reproduce. Inside a host, it behaves like a living organism.
Q2. Mules do not reproduce. Are they considered living?
Ans: Yes, as they show metabolism, consciousness, and growth.
