Question

23 multiple choice 2 points claim - archaebacteria and eubacteria belong to separate kingdoms. what is the best piece of evidence to support this claim? archaebacteria cell walls do not contain peptidoglycan; but eubacteria cell walls do archaebacteria are multicellular organisms while eubacteria are unicellular organisms eubacteria live in extreme environments eubacteria are eukaryotes and archaebacteria are prokaryotes

Explanation:

Archaebacteria have cell - walls without peptidoglycan, while Eubacteria have cell - walls with peptidoglycan, which is a significant structural difference. Both are unicellular prokaryotes, and Eubacteria do not typically live in extreme environments compared to Archaebacteria.

Answer:

Archaebacteria cell walls do not contain peptidoglycan; but Eubacteria cell walls do
