Answer:
D. Alveoli
Explanation:
Functionally, the respiratory system is separated into a conducting zone and respiratory zone:
Conducting zone consists of the nose, pharynx, larynx, trachea, bronchi, and bronchioles. These structures form a continuous passageway for air to move in and out of the lungs.
Respiratory zone is found deep inside the lungs and is made up of the respiratory bronchioles, alveolar ducts, and alveoli. These thin-walled structures allow inhaled oxygen (O2) to diffuse into the lung capillaries in exchange for carbon dioxide (CO2).
The respiratory zone begins where the terminal bronchioles join a respiratory bronchiole, the smallest type of bronchiole, which then leads to an alveolar duct, opening into a cluster of alveoli.

Answer:
A. Erosion from wind, water, or ice removes crustal material.
Explanation:
Plain formation can occur in many different ways some plates some planes can form as wind, water and ice erode wear away or remove dirt and rocks on higher land.
Wind picks up and carries along small particles which can be abrasive against surfaces, slowly wearing them away to form more particles. The water and ice transport the fragments of rock and dirt as sediment down hillsides, where it is eventually deposited. This occurs until several layers of sediment are accumulated. Plains can also form at the bases of mountains where water carries a flow of sentiments downhill to flat areas where it further spreads out to deposit the sediment in a fan shape -this is called an alluvial plain.
