Answer:

By difference in there ribosomal RNA sequence

Explanation:

Both bacteria and archaea lack membrane-bound nucleus and earlier both are considered in the same categories. Carl Woese was the scientist who discovered that bacteria and archaea are not similar.

Carl Woese and his lab members checked the ribosomal RNA in some archaeans and concluded that the archaeans are more closely related to eukaryotes than bacteria. After the study on archean Carl Woese classified the prokaryotes into two domains i.e., bacteria and archaea.  

Therefore by difference in the ribosomal RNA sequence archaeons first distinguished from other prokaryotes.

When hypothesizing a possible phylogeny in order to classify taxa,scientists incorporate systematics to
Svet_ta [14]

Answer:

B)provide molecular or genetic information, as well as morphological information.

Explanation:

Systematics is the science of classification and phylogeny reconstruction. Studies diversity as a consequence of evolutive history and establishes the bases to reconstruct biological patterns and formulate hypotheses to explain the processes of these patterns. It reconstructs the origin and diversification of a taxon. Systematics creates systems of classification represented in a tree. Taxonomy is based on systematics.

The main goal of systematics is to solve the genealogical relationship between different species and biological groups that produces natural clusters.

Systematic considers morphological characters, as well as physiological, cytological, molecular, and behavioral characters.
