Question

Why do naked (non-enveloped) viruses exhibit greater resistance to environmental changes compared to enveloped viruses?
Options
A They have a more complex capsid structure.
B Their genetic material is protected solely by a durable capsid, lacking a fragile outer lipid membrane.
Correct Answer
C They are capable of autonomous reproduction outside a host.
D They can crystallize, making them impervious to damage.
Correct Answer

Option B is the correct answer.

Detailed Explanation

The document states, 'A naked virus exhibits greater resistance to environmental changes and is less susceptible to conditions that can damage the enveloped viruses. This is because it lacks a fragile outer lipid membrane; instead, its genetic material is protected solely by a capsid.'

Hint

Consider the nature of the outermost layer of each type of virus.
