Viruses are not classified within any of the three domains of life, which are Bacteria, Archaea, and Eukarya. They do not fit into the domains of Animalia or Protista, as they are acellular entities that require a host cell to replicate and do not possess cellular structures. Instead, viruses are considered separate biological entities.

Which is not a kingdom in the eukarya domain?
Bacteria archaea
How many DOMAINS are used in Biology?
threeA domain is a taxonomic level that supersedes kingdom, emphasizes the characteristic similarities among eukaryotic kingdoms (Protista, Plantae, Fungi, and Animalia), and discriminates between Archaea and Eubacteria. Systematists recognize 3 domains: Eukarya (membrane enclosed nucleus, organelles), Archea (numerous prokaryotic extremophiles), and Eubacteria (prokaryotic, peptidoglycan cell walls). Cladistically, Eukarya are believed to share a common ancestor with Archaea more recently than Eubacteria; evidence includes the presence of histones, introns, and the initiator amino acid Methionine (protien synthesis). -----------------------------------------------------------------------------------------------------No, FourThe answer above is outdated; the four domains are eukaryotes, bacteria, Archaea, and viruses.
What characteristic applies to all 3 domains and viruses?
All three domains of life—Bacteria, Archaea, and Eukarya—share the characteristic of being composed of cells, which are the basic units of life. Additionally, viruses, although not classified as living organisms, possess genetic material (DNA or RNA) and can evolve, similar to cellular organisms. This shared feature of genetic material underscores the fundamental biological processes of replication and evolution across all domains and viruses.
How domains are there?
The four domains are eukaryotes, bacteria, Archaea, and viruses.
What domain does the protista kingdom belong to?
== == At one time, bacteria were also considered protists, under the three-kingdom system of Animalia (corresponding closely to the modern kingdom), Plantae (which included Fungi as well as plants), and Protista (everything else). Now, living organisms are are put into 6 kingdoms: # plantea (plants): phototrophic, multicellular, form embryos # animalia (animals): heterotrophic, multicellular, form embryos # mycetea (fungi) : heterotrophic, multicellular or unicellular, with chitin cell walls # protoctista (commonly known as protista) (algae, protozoa, slime molds): photototrophic or heterotrophic, multicellular or unicellular, don't form embryos, no chitin cell wall.The protists can vary greatly from all the rest of the kingdoms, in that they can also be mixotrophic. They can also reproduce asexually in one host, then produce sexually in another host. They can be unicellular, colonial, or multicellular. # eubacteria (modern bacteria): prokaryotic. # archaebacteria (ancient bacteria): also prokaryotic. viruses are not considered organisms
What kingdom do viruses and bacteria belong to?
Viruses are prokaryotes and not Eukaryotes. Therefore they are not alive. Since it is not considered to be alive they do not belong in the 5 kingdom classification; Monera, Fungi, Plantae, Animalia, Protista. Bacteria are living once celled organisms and belong to either bacteria or Archaea. *Viruses not considered alive because they need a host to be able to reproduce. They cannot reproduce on their own.
Why don't viruses have the same structure as the five kingdoms?
Viruses are not considered to belong to any of the five kingdoms of life (animalia, plantae, fungi, protista, and monera) because they lack the characteristics of cells such as organelles, cellular structure, and metabolism. Viruses are considered acellular as they are composed of genetic material (DNA or RNA) surrounded by a protein coat, and they require a host cell to replicate.
What characteristic applies to all three domains and viruses?
They have genetic material. (Novanet)
How many domains are there?
The four domains are eukaryotes, bacteria, Archaea, and viruses.
What are the five basic group of microorganisms?
the 5 basic group of microorganisms are 1. Monera 2.Protista 3.Fungi 4.Animalia 5.
Which two groups are the most similar in physical characteristics Archaea and Eubacteria Archaea and viruses Eukarya and Eubacteria Archaea and Eukarya?
Archaea and Eubacteria are the most similar in physical characteristics, as both are prokaryotic organisms lacking a nucleus and membrane-bound organelles. They share similar cellular structures, such as the presence of a cell wall and the ability to reproduce asexually. In contrast, viruses are acellular and do not possess the cellular structures found in Archaea or Eubacteria, while Eukarya have more complex cellular characteristics.
Do viruses belong to one of the domains of life?
For all practical purposes, viruses are not considered to be alive. The cells and organisms they infect are considered to be alive. This is because viruses are just a piece of DNA in a protein shell. Without a host they cannot reproduce or even function. In fact when one is outside a cell, let's say just floating in the air they are called virions and are in a sort of catatonic state. It isn't until they make contact with another living thing that they do really anything whatsoever. So in a nutshell, most academic circles do not believe they can technically be alive since they reproduce so bizarrely, they don't have the right anatomy, and they just don't do enough.
