I believe this process is known as Assimilation. In this process nutrients are absorbed into the body after digestion in the intestine and its transformation in biological tissues and fluids. Assimilation is different from absorption as absorption involves the process of moving food from the digestive system into the blood system for the transportation to all body parts, while assimilation is the uptake of nutrients into cells and tissues and consequent building up into mores complex substances.
Answer:
The correct answer is C. An oxygen
Explanation:
Amino acid is a compound which serves as the building block or proteins. They are the smallest and simplest unit of protein. They contain carbon, oxygen, hydrogen, and oxygen.
Each amino acid has a central carbon atom which is designated as alpha carbon which is attached with a carbonyl functional group, an amino-functional group, a hydrogen atom, and a side chain(R group). So oxygen is not bound directly with the central carbon atom.
The R group is different in different amino acid. Glycine is the simplest amino acid and it has H in place of the R group.
The nervous system and the muscle system respond to stimuli to produce motion. The skeletal movements of muscles are mostly voluntary.
Involuntary movements occur in these muscles when the nerve impulse passes from a sensory neuron to a motor neuron via an interneuron in the spinal cord.
<h3>What are Skeletal muscles?</h3>
Skeletal muscles may be defined as the muscles that fasten to your bones and authorize you to achieve a broad range of activities and operations.
Skeletal muscles control the direct movement of a person's will and are hence referred to as voluntary movement.
While the spinal cord is associated with both movements directly or indirectly. It is a prolonged, delicate tubelike network liable for holding incoming and outgoing messages through the brain to the rest body.
Therefore, it is well described above.
