Final answer:

The Domain Archaea differs from the Domain Bacteria in cell wall composition, membrane structure, and biochemistry, including tRNA composition, ribosome structure, and antibiotic sensitivity; hence, all listed choices are correct.

Step-by-step explanation:

The differences between the members of the Domain Archaea and the Domain Bacteria can be attributed to several factors.

First, Archaea lack muramic acid in their cell walls, distinguishing their cell wall composition from bacteria, which have peptidoglycan. Second, in terms of membrane structure, Archaea have isopranyl glycerol ethers rather than fatty acid esters, which are typical of bacterial membranes.

Lastly, the overall biochemistry of Archaea reflects more similarities with eukaryotic cells, including differences in tRNA composition, ribosomal structure, and antibiotic sensitivity when compared to bacteria. Therefore, all of the choices mentioned contribute to the differences between these two domains.
