Provide brief overview of the nervous system and its role in the maintenance of homeostasis.
Alona [7]
Explanation:

The nervous system has two major anatomical subdivisions:

Central Nervous System: Composed of the brain (inside the skull) and the spinal cord (inside the spinal column).

The brain and spinal cord are responsible for processing and integrating the various sources of information to allow us to develop a response. Therefore, the main function of the somatic nervous system is to connect the Central Nervous System with the organs and skeletal muscle to carry out our daily functions.

Peripheral nervous system: it is everything that is outside the bone cavity and is formed by the nerves and nerve ganglia that extend outside the central nervous system.

The peripheral nervous system has a somatic component, which is associated with the voluntary control of body movements through the use of skeletal muscles. This means that it is responsible for all the functions that we are aware of, including the movement of our arms, legs, and other parts of our body.

On the other hand, the autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiological processes. These processes include heart rate, blood pressure, breathing, digestion, and sexual arousal. The autonomic nervous system contains three divisions: sympathetic, parasympathetic, and enteric.

Due to the above relationships and anatomical subdivisions we can say that the nervous system is responsible for regulating and maintaining homeostasis. In fact, through its receptors, neurotransmitters, nervous inputs, and outputs, the nervous system keeps us in touch with our environment, both external and internal.

We can conclude that the correct answer is:

Sequence of amino acids in a polypeptide chain of protein molecule coresponds to the sequence of nucleotides on mRNA for that pr
tamaranim1 [39]

Answer:

330

Explanation:

A codon is the sequence of three nucleotides on mRNA that refers for particular amino acid during translation (protein synthesis) process. The four nucleotides arrange themselves in various combinations to produce different codons. The tRNA with corresponding anticodon attach the particular amino acid to polypeptide chain during translation.

Remember there is always a stop (UAA) and start codon (AUG) for the synthesis of polypeptide and stop codon does not contribute for any amino acid. It just terminate the polypeptide chain synthesis. We know that a codon is made up of three nucleotide so our calculation will be.

                                     993-stop codon =990

                                     990/3=330

So that's why 330 amino acid will be incorporated in the polypeptide chain.
