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.
As the intense competition of the species are observed in clumped distribution, so the answer is distribution of individuals will tend to be clumped.
<h3>
What is intraspecies competition?</h3>
The competition which occurs between individuals of the same species based on common need for a limited resources, leading to a reduction in the survival and reproduction rate.
Intraspecific competition for exploitation which is an indirect type observed when an individual consumes the available resources.
Intraspecific competition by interference observed when the individuals fight to access for other's food.
Hence, answer is clumped.

Answer:
Moist walls - gases dissolve in the moisture helping them to pass across the gas exchange surface. Permeable walls - allow gases to pass through. Extensive blood supply - ensuring oxygen rich blood is taken away from the lungs and carbon dioxide rich blood is taken to the lungs.
Answer:
Water will move in and out of the cell equally
Answer:
Los organismos eucariotas incluyen protozoos, algas, hongos, plantas y animales. ... Sobre todo, las células eucariotas se definen por la presencia de un núcleo rodeado por una membrana nuclear compleja. Además, las células eucariotas se caracterizan por la presencia de orgánulos unidos a la membrana en el citoplasma.
