• capitalized but not printed distinctively, italicized, or underlined
  
• talicized or underlined
• capitalized and italicized or underlined

Viruses are denied a kingdom of their own because

• they are too poorly understood
• they are too small

• Archaebacteria
• protista

• do not normally interbreed with other species in nature
• can be distinguished from other species
• are incapable of hybridization with other species
• remain relatively constant

Prokaryotic organisms make up the

• Archaebacteria, Eubacteria, and Protists
• Archaebacteria and Protists
• Eubacteria and Archaebacteria
• Protists

In the current taxonomic system, families are grouped into

• classes 
• phyla 
• kingdoms 
• orders
