Question

Taxonomists name living species and classify them into broader groups. The Domain Bacteria and Archaea contain organisms with simple cells. The Domain Eukarya includes various protists and the kingdoms Fungi, Plantae, and Animalia. From the list, pick all of the descriptions of members of the Domain Archaea:

(a) Extreme halophiles (salt-loving archaea)
(b) Methanogens (methane-producing archaea)
(c) Thermophiles (heat-loving archaea)
(d) All of the above

Answer 1

Members of the Domain Archaea include extreme halophiles, methanogens, and thermophiles, which means all of the listed options (a, b, c) are correct.

Step-by-step explanation:

Taxonomists classify living organisms into three domains: Bacteria, Archaea, and Eukarya. Members of the Domain Archaea are single-celled prokaryotic organisms that lack a nucleus and often live in extreme environments. From the list provided, all of the descriptions (a) Extreme halophiles, (b) Methanogens, and (c) Thermophiles are correct descriptions of members of the Domain Archaea. These include salt-loving, methane-producing, and heat-loving archaea, respectively.
