Explanation:
The five-kingdom system of classification for living organisms, including the prokaryotic Monera and the eukaryotic Protista, Fungi, Plantae and Animalia is complicated by the discovery of archaebacteria.
Ans.
DNA acts as genetic material in all living organisms that store and transmit genetic information from one to next generation. DNA sequence carries instructions for the expression of genes to make proteins, responsible for different phenotypic characters of individuals.
The DNA, first synthesizes mRNA molecule that carry information for the protein synthesis, in the form of codons and code for a specific polypeptide chain or protein.
The sequence present in DNA determines the amino acid sequence in protein encoded by the DNA. Change in DNA sequence affects gene expression as it leads to change in mRNA sequence, and thus, change in sequence of amino acid of the resulting protein.
The location that should have lowest oxygen concentration would be the tissue because it is the furthermost location.
Other location with lowest oxygen concentration should be in the right part of the heart. It is when all unoxygenated blood pooled before going to the lungs. But the left part of the heart will have highest oxygenated blood, so it's ambiguous.
High oxygen concentration should be found in the environment, lungs, and the blood.
