COMPLETE SOLUTIONS
What are the various types of microbes that can colonize humans? What are they called
when they cause disease? - ANSWERBacteria, Archaea, Protozoa, Fungi, Helminths,
Viruses; Pathogens
What are the three domains of life? What are their key differences? Why are viruses not
a domain? - ANSWERBacteria: no nucleus, typically single celled; Archaea: no nucleus,
typically single celled; Eukarya: nucleus, single and multi celled, larger

Bacteria, Archaea, Virus
How do we utilize microbes for other purposes to advance society? -
ANSWERBiotechnology- manipulation of microorganisms to make products in industrial
field
Genetic Engineering- modifying plants and animals to create GMO's (food) or drugs,
hormones, and enzymes
