Which best explains why viruses are not classified by Linnaean taxonomy?
Viruses do not contain any genetic information or a cell wall.
Viruses share many characteristics with several of the kingdoms.
Viruses cannot reproduce outside a host cell and are therefore nonliving.
Viruses lack a protein coat and any metabolic activity.
Viruses are not classified by Linnaean taxonomy because they do not fit into the traditional classification system. They have unique characteristics that make it difficult to place them within the established kingdoms.
