What are the three domains of life

Answer:

The three domains of life are Bacteria, Archaea and Eukarya.

Explanation:

Three domain system is a classification system of living beings that is based on the comparison of ribosomal RNA.

Bacteria: Which includes all the majority of unicellular microscopic living beings or that form aggregates, without nucleus or cellular organelles, are also characterized by having a peptidoglycan cell wall.

Archaea: Like bacteria, all its members are unicellular and without nucleus although they differ in fundamental things such as the composition of their outer wall or their metabolic pathways, much more complex than those of bacteria, almost close to those of urkaryotes.

Eukarya: Finally, the eukaryotes that were the last to appear evolutionarily speaking, includes all the organisms with nucleus and that present organelles such as mitochondria or chloroplasts, with more complex biochemical routes that allow greater structural complexity, beyond the unicellular ones.

An ideal gas is a theoretical gas in which inter molecular forces do not exist among the molecules and the molecules do not occupy any space. A gas that does not obey ideal gas law are described as non ideal in behaviour. Gases that are most susceptible to non ideal behaviour are those that have attractive and repulsive forces among their molecules and whose particles have volume. Gases that exhibit non ideal behaviour has compressiblity factor ratio that deviate from 1.
