Barium is a chemical element with symbol Ba and atomic number 56. It is the fifth element in Group 2, a soft silvery metallic alkaline earth metal. Because of its high chemical reactivity, barium is never found in nature as a free element. The hydroxide, known in pre-modern history as baryta, does not occur as a mineral, but can be prepared by heating barium carbonate.
Organisms are classified by cell type in the three domain systems. 1. Living organisms are classified into three domains (Bacteria; Archea and Eukarya) based on similarities in ribosomal RNA (rRNA). rRNA mutates less over time compared to DNA.(Also look at tRNA & mRNA but to lesser extent).2..
