Which statement best describes how Carl Woese changed the system of classification?

b

He added a level and a kingdom.

Answer: Carl Woese introduced three domains of biological qualification.

Explanation:

Woese divided the domains of the steel form of life into archaea, bacteria, and eukaryotes. In his research, he particularly emphasized the separation of prokaryotes into two groups called Eubacteria and Archaebacteria. Woese used the term "kingdom" to refer to the three primary phylogenetic groups, and this nomenclature was widely used until the name "domain" was adopted in 1990.
