Answer 2

Answer:

Explanation:

Archaea (/ɑːrˈkiːə/ (listen) ar-KEE-ə; singular archaeon /ɑːrˈkiːən/) represent a website of single-celled organisms. These microorganisms lack mobileular nuclei and are consequently prokaryotes.

Archaeal cells have particular homes keeping apart them from the alternative  domains, Bacteria and Eukaryota. Archaea are in addition divided into more than one identified phyla. Classification is tough due to the fact maximum have now no longer been remoted in a laboratory and were detected most effective via way of means of their gene sequences in environmental samples.

Archaea are a first-rate a part of Earth's life. They are a part of the microbiota of all organisms. In the human microbiome, they're crucial withinside the gut, mouth, and at the skin. Their morphological, metabolic, and geographical range allows them to play more than one ecological roles: carbon fixation; nitrogen cycling; natural compound turnover; and keeping microbial symbiotic and syntrophic communities.
