Portage Learning BIOD 171 Module 6 Questions and Answers 100% Pass True or False: viruses can be classified as prokaryotic or eukaryotic False. Viruses are neither prokaryotic or eukaryotic What is an obligate intracellular parasite? viruses cannot replicate unless inside a living host cell. As a parasite, a virus depends on its living host to provide the framework (proteins, etc) to replicate—to make additional copies of itself. What is a viral capsid? a membrane-like protective structure t...
