Answer:
The correct answer will be- by lowering the surface tension at air/liquid transition.
Explanation:
Pulmonary surfactant is the mixture of proteins and lipids produced by the type II epithelial cells.
The surfactant is selected into the alveolar sacs where the surfactant reduces the surface tension of the air/liquid interface to 1 mN/m. The lipid content of the surfactant called dipalmitoylphosphatidylcholine or DPPC forms a surface film which lowers the surface tension.
This power surface tension reduces the work of breathing and thus prevent the alveolar sac from rupture or collapse.
Thus, by lowering the surface tension at air/liquid transition is the correct answer.
Answer:
Depends...
Explanation:
You need to include more information regarding the question. If the question is referring to the roots of the plant then the answer would be water. If the questions asks about the area of the leaves/amount of leaves then it would be sunlight. If the question is talking about stomatal pores then it would be carbon dioxide.
Hope this helps,

Without the naming and classification system, our list of organisms names would just be a pile of names. This is because without the classification system, animals are just animals and there is no way to put similar animals together. Without the naming system, when you heard an animals name, you wouldn't get any idea at all about the animal.
