1. Two organisms can be of different kingdoms, but the same domain. 2. Two organisms can be of different domains but the same kingdom. Identify the true statement and explain why

The correct option is A, where two living organisms can be from the same domain but not from a mother kingdom and this is due to the classification of the domain at a taxonomic level that is above the kingdom, that is why it is more comprehensive.

Explanation:

In biology, the domain is a taxonomic category used in biological classification systems, above the kingdom and the super kingdom. The domain has been added above the kingdoms to classify the three taxa: archaea (Archaea), bacteria in the restricted sense (Bacteria sensu stricto) and eukaryotes (Eukarya); while the category of empire or super kingdom was added by taxonomists who needed a category above the kingdoms to locate in it the prokaryotic (or Bacteria in a broad sense) and eukaryotic taxa.

The three domains were proposed by Carl Woese in 1990 when he created, applying the new cladist taxonomy, his system of three domains. 1 He proposed the three domains on the basis of a phylogenetic tree hypothesis in which those 3 clades diverged from an ancestral parent. Alternatively, in a traditional evolutionary systematics, living beings are classified in a System of two super-kingdoms, or if the empire category of two empires is used: Prokaryota and Eukaryota; the name of the two groups refers to the presence or absence of a cell nucleus, a character accompanied by a significant number of characters that define each group. Today the prokaryotic group can be considered to be paraphyletic, since the eukaryotic domain originates from prokaryotic ancestors.

Viruses are completely dependent biological systems, parasites, which many scientists prefer to consider as non-living, so they are classified separately. For them, the informal domain Acytota (acellular) has been proposed.
