Answer
- Adaptation
- Genetic material
- Reproduce
Explanation:
In principle, viruses are considered as non living because they don't fulfill all eight characteristics of living organisms, i.e. RAREHOGG (reproduction, adaptation, response to stimuli, energy production, homeostasis, organization of cells, growth and development, and genetics). Specifically, they don't have energy metabolism, they don't grow, they don't respond to stimuli. However, they can adapt the environment and reproduce. But they do not reproduce independently, rather they need a host cell and use its machinery for reproduction. Based on these reasons, they are considered as living organisms.
