Surfactant helps to prevent the alveoli from collapsing by
Y_Kistochka [10]

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.

Elanso [62]

Answer:

DNA is the genetic material of all the living organism except some viruses. The structure and the characteristics of the DNA was well explained by Watson and Crick.

DNA is a double stranded molecule in which nitrogenous bases are linked together. Watson and crick explained that DNA strand are antiparallel. The antiparallel nature of the strand means one DNA gas a polarity of 5' to 3' direction whereas the another strand of the DNA gas polarity of 3' to 5' direction. These two strands has opposite polarity and runs in anti parallel directions. Thus, the DNA strand known as antiparallel strands.
