<span>Harmful traits are produced by most mutations. S</span>ometimes the mutation can create nonsense codons that do not produce any amino acid and signals the cell to end the process. So, this causes the cell to do different things than what it was meant to. Most mutations are destructive and cells have a method of examining if they have mutated or not. Its only when the checking fails that the cell becomes mutated.
Answer:
The somatic nervous system.
Explanation:
The nerves which are present outside the central nervous system comprises the peripheral nervous system.
The peripheral nervous system is divided into two types: the somatic system which controls the voluntary actions through skeletal muscles and the autonomic system which controls the automatic responses of the human body.
The somatic neurons send the signals from the receptors to the CNS through the sensory nerves and the motor neurons send the signals from the CNS to the muscles.
Thus, somatic nervous system is correct.
The correct answer is false.

All the steps of GPCR signaling would be prevented in the presence of a beta-blocker drug.
<h3>What is Beta-blocker?</h3>
Beta-blocker may be defined as a kind of medication that chokes the activity of substances, such as adrenaline, on nerve cells and provokes blood vessels to relax and dilate.
Adrenergic receptors choke the attachment of catecholamine that is epinephrine to the G-protein. G-protein activates adenylyl cyclase which in turn activates protein kinase A.
But when the beta-blocker drug is subjected to this pathway, it blocks the attachment of the hormone to their receptors, hence none of the pathway or steps would be carried forward. This is because signaling is not initiated.
Therefore, all the steps of GPCR signaling would be prevented in the presence of a beta-blocker drug.
