Detailed explanation-1: -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-2: -Which of the following is the MOST important reason that Archaea and bacteria belong to separate biological domains? Archaea are less likely to inhabit the bodies of animals than bacteria.
Detailed explanation-3: -The third domain, Eukarya, consists of organisms whose cells have a nucleus. It’s also the only domain that contains multicellular and visible organisms, like people, animals, plants and trees.
Detailed explanation-4: -All of life can be divided into three domains, based on the type of cell of the organism: Bacteria: cells do not contain a nucleus. Archaea: cells do not contain a nucleus; they have a different cell wall from bacteria. Eukarya: cells do contain a nucleus.
