What term describes harmless microorganisms with useful functions?

• A. Disease
• B. Nonpathogenic
• C. AIDS
• D. HIV

Answer: (B)

Harmless microorganisms with useful functions are nonpathogenic. Nonpathogenic organisms do not cause disease and can even benefit the body, such as forming protective skin flora or aiding in various biological processes. This contrasts with pathogens, which cause disease. The terms disease, AIDS, and HIV refer to illness or a specific virus, not to harmless or beneficial microbes. So nonpathogenic is the precise description for microbes that are harmless and functionally useful.
