EVERYDAY SCIENCE

Detailed explanation-1: -For example, in the most inclusive grouping, scientists divide organisms into three domains: Bacteria, Archaea, and Eukarya. Within each domain is a second level called a kingdom.

Detailed explanation-2: -Organisms can be classified into one of three domains based on differences in the sequences of nucleotides in the cell’s ribosomal RNAs (rRNA), the cell’s membrane lipid structure, and its sensitivity to antibiotics. The three domains are the Archaea, the Bacteria, and the Eukarya.

Detailed explanation-3: -The Kingdom is the largest and most inclusive of the taxonomic categories.

Detailed explanation-4: -The prokaryotes are by far the most abundant organisms inhabiting planet Earth. They are also by far the most diverse, both metabolically and phylogenetically; they encompass the Bacteria and the Archaea, two out of the three major divisions of living organisms.

Detailed explanation-5: -Domain Eukarya, which consists of all eukaryotic organisms, or those with the largest, most complex cells and the most advanced compartmentalization.
