Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Archaea and Bacteria are two prokaryotic domains.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The two prokaryote domains, Bacteria and Archaea, split from each other early in the evolution of life. Bacteria are very diverse, ranging from disease-causing pathogens to beneficial photosynthesizers and symbionts. Archaea are also diverse, but none are pathogenic and many live in extreme environments.

Detailed explanation-2: -The two-domain system is a biological classification by which all organisms in the tree of life are classified into two big domains, Bacteria and Archaea.

Detailed explanation-3: -Scientists refer to both bacteria and Archaea as “prokaryotes”–a cell type that has no distinct nucleus to contain the genetic material, DNA, and few other specialized components.

Detailed explanation-4: -The three domains are the Archaea, the Bacteria, and the Eukarya. Prokaryotic organisms belong either to the domain Archaea or the domain Bacteria; organisms with eukaryotic cells belong to the domain Eukarya.

Detailed explanation-5: -The three domains of living organisms. Bacteria and Archaea are both prokaryotes but differ enough to be placed in separate domains. An ancestor of modern Archaea is believed to have given rise to Eukarya, the third domain of life. Major groups of Archaea and Bacteria are shown.
