Answer:
Remarkably efficient alveolar macrophages crawl freely along the internal and external alveolar surfaces
Explanation:
The alveolar macrophages are present on the internal lumenal surfaces of the alveolar ducts, the alveoli, and the bronchioles.
Alveolar macrophages are phagocytes that uses several surface receptors to release many secretions, to interact with other cells and molecules.
But the alveolar macrophages are intact to the inner surface only and do not crawl freely along the internal and external alveolar surfaces.
Hence, the correct option is " C".
The correct answer for the question that is being presented above is this one: "6H2O, NADP, light energy, 18ADP + Pi." The input of the light-dependent reactions, labeled X is that <span>6H2O, NADP, light energy, 18ADP + Pi.</span>
