Question

viruses lack organelles and consist of genetic material encased in a protein coat. their simplicity and inability to carry out most life functions
make them a poor tool for biotechnological applications.
suggest that all life evolved from viruses.
make them a weak class of pathogen.
support the theory that they arose as escaped fragments of organismal nucleic acids.
explain why they evolve so rapidly.

Explanation:

Viruses' simplicity and lack of ability to perform most life - functions support the theory that they originated as escaped fragments of organismal nucleic acids. They are not poor for biotechnological applications (used in gene therapy etc.), there's no evidence all life evolved from them, they are not necessarily weak pathogens, and their simplicity doesn't explain rapid evolution.

Answer:

support the theory that they arose as escaped fragments of organismal nucleic acids.
