Solution

  1. Molecules that compose the membranes: The cell membranes of Bacteria and Archaea are composed of different molecules. Bacteria have a lipid bilayer made up of phospholipids, while Archaea have a lipid monolayer or bilayer made up of ether lipids.

  2. Cell size: The cell size does not typically differ between Bacteria and Archaea. Both are generally small, microscopic organisms.

  3. Evolutionary relationship to eukaryotes: Archaea and eukaryotes are more closely related to each other than either is to bacteria. This is based on genetic sequences that are more similar between Archaea and eukaryotes.

  4. Location of DNA: Both Bacteria and Archaea are prokaryotes, meaning they do not have a nucleus. Therefore, the DNA in both is located in the cytoplasm.

  5. Presence of cell wall in most: Both Bacteria and Archaea typically have a cell wall. However, the composition of these cell walls differs. Bacterial cell walls contain peptidoglycan, while Archaeal cell walls do not.

So, the options that differ between domains Bacteria and Archaea are: molecules that compose the membranes, evolutionary relationship to eukaryotes, and presence of cell wall in most.
