Final answer:
Both computer viruses and biological viruses can infect and spread, though computer viruses do not have genetic material or undergo cellular processes.
Step-by-step explanation:
How computer viruses are similar to biological viruses is a question that reveals the interesting ways in which non-living entities can mimic certain characteristics of living organisms. Both computer viruses and biological viruses can infect and spread from one host to another. However, computer viruses lack genetic material and do not undergo cellular processes such as division. Biological viruses, although not considered truly living because they are not cellular and cannot metabolize or grow by themselves, contain either DNA or RNA as their genetic code, a hallmark of life. They must infect a host cell and use the cell's machinery to produce progeny virus particles or virions. The correct answer to the student's question is A) Both can infect and spread.
