Quizplus · Accepted Answer

The simplicity of viruses and their lack of organelles suggest that they may have originated as fragments of organismal nucleic acids that escaped and became free-living.

Answer: D 
 The inability of viruses to carry out most life functions explains why they evolve so rapidly, as their survival depends on quickly adapting to host defenses and changing environmental conditions.

Note: Options A, C, and E are incorrect. Option A is incorrect because viruses can be highly pathogenic, such as the Ebola virus. Option C is incorrect because viruses are not considered to be a common ancestor of all life forms. Option E is incorrect because viruses can be useful in biotechnological applications, such as in the creation of vaccines and gene therapy.
