Final answer:
The major difference between a kingdom and a domain is that a domain is a more inclusive taxonomic category. The answer to the question is that all prokaryotes belong to one of the two domains: Bacteria or Archaea.
Step-by-step explanation:
The major difference between a kingdom and a domain is that a domain is a larger and more inclusive taxonomic category above the kingdom level. According to the question, the correct answer is E) All prokaryotes belong to one domain. This is because the three domains of life on Earth are Bacteria, Archaea, and Eukarya. Both Bacteria and Archaea domains consist of prokaryotic organisms that lack a nucleus, and therefore, all prokaryotes are classified within these two domains. In contrast, the domain Eukarya is comprised of organisms with eukaryotic cells that have a nucleus including kingdoms like the animals, plants, fungi, and protists.
