Question

What are 3 domains of living organisms and what do they mean?

Answer 1

Hint: Taxonomy is a scientific study in biology that identifies, defines and categorises biological organism groups based on shared features. Biological classes apply taxonomic rankings, including: domain, kingdom, phylum, class, order, family, genus, species and strain (in order from most to least inclusive), etc.

Complete answer:
Archaea is the most well-known type of prokaryote (single-celled life forms without a core). Microorganisms that have been around for a long time and are used to living in extreme conditions. Archaea are prokaryotic cells distinguished by membrane lipids that are fanned hydrocarbon fasteners linked to glycerol via ether linkages. The presence of these ether linkages in Archaea increases their ability to withstand extreme temperatures and highly acidic conditions, despite the fact that many archaea live in mild conditions. Archaea includes halophiles, which are organic entities that thrive in extremely pungent conditions, and hyperthermophiles, which are living beings that thrive in extremely hot conditions.
Bacteria are any remaining microbes (i.e that are not under Archaea). Despite the fact that microorganisms are prokaryotic cells similar to Archaea, their layers are made of phospholipid bilayers. Microbes are represented by cyanobacteria and mycoplasmas. They are distinct from Archaea in that they lack ether linkages, and they are grouped into an alternate class—and thus an alternate space.
All eukaryotes are classified as Eukarya (cells that have a nucleus could in any case be unicellular, though).
Eukaryotes are members of the space Eukarya with film-bound organelles (including a core containing hereditary material) and are addressed by five realms: Plantae, Protista, Animalia and Fungi.

Note:
People, animals, and plants are all classified as Eukarya.
Archaea will never occur in the life of a normal person because they live in inhumane conditions.
Domains used to be the most general arrangement of life.
