The walls of the alveoli are composed of two types of cells, type I and type II alveolar cells. The function of type II alveolar cells is to secrete surfactant.

Explanation:

Type II cells have great importance in the synthesis, storage, and secretion of lung surfactant, which acts to reduce surface tension and prevent collapse of the alveoli, reducing the pulmonary tension, it helps the respiratory mechanics, minimizing the energy that the lung tissue must provide to keep the gas exchange surface open and exposed during successive inspiration-expiration cycles. Type II cells comprise up to 14% of all alveolar epithelial cells.

i believe it would be the lungs.

tsd is temerature dependent sex determination.

tsd: it is a type of environmental sex determination in which the temperature experienced during embryonic/ larval development (ambient temperature for development) determine the sex of the offspring.

crocodile displays the tsd where the ambient temperature of the developing egg determines the individual's sex. for example in the american alligator's eggs, incubation at 33 ºc produces mostly males, while incubation at 30 ºc produces mostly females. so if the american alligator's egg will get the ambient temperature (33 degree celcius)during embryonic development from egg, the offspring will be male and same for the female sex determination.
