EVERYDAY SCIENCE

Detailed explanation-1: -All living organisms are classified into three major domains: Domain Eukaryota (eukaryotes), Domain Eubacteria (true bacteria), and Domain Archaea (archaebacteria). Domain Eubacteria includes the true bacteria. It is the largest domain that includes a large group of organisms.

Detailed explanation-2: -Members of the domain Bacteria are unicellular and prokaryotic. This domain corresponds to the kingdom Eubacteria.

Detailed explanation-3: -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 are extremophiles, capable of surviving in extreme conditions (like boiling hot springs). Archaea and bacteria are two different domains of cellular life. They are both prokaryotes, as they are unicellular and lack a nucleus. They also look similar (even under a microscope).

Detailed explanation-5: -Eubacteria are called true bacteria and N-acetylmuramic and they have higher degrees of organization. Archaebacteria are called living fossils and they can survive in extremely harsh (highly acidic, high temperature, methanogenic) environments.
