NEET BIOLOGY

Detailed explanation-1: -The three-domain system for classifying organisms seems to be more accurate than previous systems now that evidence to support it has been discovered.

Detailed explanation-2: -The five Kingdom system is more specific, in a way, but the three domain system allows to go back further and recognize a common ancestor. That is one of its greatest benefits: it shows how different kingdoms are related to each other. It also explains archaebacteria much better.

Detailed explanation-3: -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-4: -Archaea. Archaea are the oldest of the 3 domains of life. They make up a group of the first organisms to appear on Earth. We know this because they are used to extreme environments like those during the early Earth.

Detailed explanation-5: -The biologists usually classify the organisms into three domain classification because there are three crucial domains: bacteria, Archaea, and Eukarya, which are different from each other in some distinct aspects, and six kingdoms where the organisms are grouped according to their characteristic features.
