In the three-domain classification of life, members of domain Archaea have more biochemical similarities with which of the following?

Bacteria
Eukaryotes
Fungi
Protista

The correct answer is: Eukaryotes

In the three-domain classification of life, members of domain Archaea have more biochemical similarities with Eukaryotes. This is because both Archaea and Eukaryotes are characterized by the presence of a distinct nucleus within their cells, a feature that distinguishes them from Bacteria and the other organisms listed. While Archaea and Bacteria share some similarities, such as lacking a nucleus, the presence of certain biochemical processes in Archaea and Eukaryotes, such as the mechanism of transcription and translation, align them more closely than with Bacteria, Fungi, or Protista.
