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.

Nina [5.8K]
It is very true that masculinity and femininity are very strongly dependent on the society in which these terms are used. While there are genetic differences underlying the phenotype of being more masculine (having a bigger jaw, more hair on the body), there are also a lot of societal factors determining what is considered to be masculine and what feminine in a society.

When two species compete for the same ecological niche, they cannot coexist because they are competing for the exact same resour
zalisa [80]
The correct answer is B. competitive exclusion.
This law refers to the fact that it is nearly impossible for two species to exist in the same place at the same time together, if they are interested in the same resources. If both species need the same thing to survive, one will have to be stronger while the other one will dwindle in number.
