Answer:
The correct answer is D.
Explanation:
Mutations in coding sequences are more likely to be deleterious to the organism than mutations in non-coding sequences.
Mutations in coding sequence is more harmful because they end up mutating the protein coding region of the DNA , which alters the function of proteins.
These mutations may cause some harmful genetic disorder or end up causing cancer. That is why mutations in coding sequences are more harmful to the organism than mutations in non-coding sequences.

Answer:
The correct answer will be option-C
Explanation:
The rhythm of the heartbeat is controlled by the pacemaker of the heart called the sino-atrial node.
The SA node generates action potentials which trigger the contraction and relaxation of the atrium and ventricles. The membrane potential generation initiates by the depolarization of the cell membrane when the L type of Ca⁺² ions opens up and calcium ions enter the cell.
This depolarizes the cell until the potential threshold is reached which lies between the -40 and -30 mV.
Thus, Option-C is the correct answer.
The phrenic nerve, which controls the diaphragm
