Air moves through the respiratory system in a continuous cycle. which of the following correctly describes the movement of air through the parts of the respiratory system?
a) nose, trachea, bronchioles, alveoli, cells
b) nose, pharynx, alveoli, bronchioles, capillaries
c) trachea, bronchi, pharynx, capillaries, cells
d) trachea, bronchioles, bronchi, alveoli, pharynx

Option A

Explanation:

The respiratory system consists of a continuous cycle which describes the movement of the air from the nose to the cells of the body.

The air enters the body through nose and travels to the lungs via trachea. In lungs the air reaches the bronchioles which has aveoli ( sac like structure for the exchange of gases).

From here the air( oxygen) is transferred to the different cells of the body.

a. to encourage apoptosis

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
