A unicellular, prokaryotic organism is discovered by scientists. Are these characteristics enough to place it in a domain, or is more information needed?
Answer
A
More information is needed because it could be a member of Bacteria or Archaea.
B
More information is needed because it could be a member of Eukarya or Archaea.
C
These characteristics are enough because it can be determined to be a member of Bacteria.
D
These characteristics are enough because it can be determined to be a member of Eukarya.
Explanation
Being unicellular and prokaryotic narrows the possibilities to the domains Bacteria and Archaea. Both domains include unicellular organisms without a nucleus, so these traits alone cannot distinguish between them. More information is needed to determine the domain.
