The function of the respiratory system in the respiratory process is to breathe.
The respiratory system functions for the conduction of air that is rich in oxygen into the lungs and the removal of air rich in carbon dioxide to the outside.
The respiratory system facilitates the exchange of gases through processes such as breathing, inhalation as well as exhalation occurring between the air and blood and also between the blood and body cells. The respiratory system also helps in sensing smell and creating sounds.
The respiratory system controlling breathing is also termed pulmonary ventilation. In the case of pulmonary ventilation, the air is inhaled through the nasal as well as oral cavities. It then moves through the pharynx, larynx, and trachea and finally into the lungs.
Then it is followed by the exhalation of air, which will be flowing back through the same pathway where inhalation occurs. Pulmonary ventilation is triggered by changes in volume and air pressure in the lungs.
During normal inhalation, contraction of the diaphragm and external intercostal muscles takes place and then the ribcage elevates.

Answer: A
Explanation:
During the test that lead to the discovery of okazaki fragments on the lagging strand, a strand which is discontinuously synthesized with small DNA molecules to its own Primer RNA and was called okazaki fragments. The synthesis along the lagging strand is in 5' to 3' direction. As it moves, the primase synthesizes short RNA primer, to which the DNA nucleotides are added by DNA polymerase.
It was discovered that DNA synthesis is always in the 5' to 3'direction in both strands.
DNA polymerase is a directional enzyme that synthesizes leading and lagging strands during replication
Mineralogists group minerals into families based on their chemical composition. ... Most minerals are made up of combinations of chemical elements. In this group a single element like the copper shown here are found in a naturally pure form. Silicates This is the largest group of minerals.
