Question

Recent biochemical evidence divides all organisms into three domains: Bacteria, Archaea, and Eukarya. Previously, Bacteria and Archaea were viewed as one group. Which statement best describes why Bacteria and Archaea have been placed into separate domains?

Archaea were found to contain organelles, separating them from Bacteria.

They have differences in the biochemical makeup of their cell walls.

Archaea do not resemble Bacteria when viewed under a microscope.

Bacteria live in extreme environments and Archaea do not.

Answer 1

Answer: Archaea and Bacteria domains are prokaryotes because their cells do not contain membrane-bound organelles or cell nuclei. However, there are certain phenotypic, structural, and evolutionary features to distinguish Archaea and Bacteria domains.
