⩥ Which domain includes prokaryotes? Answer: Bacteria and Archaea.
⩥ Which domain includes fungi, protozoa, algae, and helminths?
Answer: Eukarya.
⩥ Are viruses included in the three-domain system? Answer: No,
because they are acellular.

Robert Koch.
, ⩥ What is taxonomy? Answer: Classification, naming, and identification
of organisms.
⩥ What did Carl Woese use to redefine classification? Answer: rRNA
gene sequencing.
⩥ What did Woese discover? Answer: Archaea are genetically distinct
from bacteria.
⩥ What is binomial nomenclature? Answer: Two-part scientific name
(Genus species).
⩥ Define horizontal gene transfer. Answer: Transfer of genes between
unrelated species.
⩥ What is the microbiome? Answer: All microorganisms and their genes
in a host/environment.
⩥ What determines resolution? Answer: Wavelength and numerical
aperture.
⩥ Shorter wavelength = better or worse resolution? Answer: Better
resolution.
