D. Proteins are composed of amino acids and determines all the structures and functions of the organism.
Answer:
Sequence of amino acids by the ribosome are the characteristic of a protein may change during a DNA mutation. Explanation: Point mutations can cause significant changes to an organism if they alter the way a protein functions. A mutation in DNA changes the mRNA, which in turn will change the amino acid chain.......

Answer:
The correct answer will be option-E.
Explanation:
The nervous system is one of the most important systems of the animal body which helps in the transmission of the signals to and fro from the body to the nervous system.
The evolution of this system is the basis of the evolution of the human species as it helped and tried the species to sense the external environment most efficiently as well as improved the response to the environment.
The nervous system improved the response by forming new interactions with each other and responding to it by reducing the response time through reflex actions which formed fast acting response to the environment. The transmission of signals improved as the cells were long-lasting that is present form the birth of an organism
Thus, option-E is the correct answer.
The ability of an organism to change internally or externally in relation to changes in the environment is called adaptation.
