The respiratory membrane, across which gas exchange occurs, is formed by the wall of the respiratory bronchiole and the pulmonary capillary. True False

False

Explanation:

We breath the carbon dioxide out and oxygen. The oxygen is required by the cell to produce energy while carbon dioxide is produced by the cells as byproduct and need to be exhaled from body. This exchange of gases is occur in lungs.

The membrane through which gaseous exchange occur in lungs is called as respiratory membrane or respiratory surface and is composed of the of alveolar epithelial cells and pulmonary capillary endothelial cells. Epithelial cells represents the cell on the outer surface of alveoli and endothelial cells represents the cells on the inner surface of capillary while pulmonary capillaries indicates the capillaries present in lungs.

So there is air present in alveoli on side of respiratory membrane and blood present on the other side of membrane in capillaries. The gases (Co2 and O2) diffuses according to difference in their partial pressure in alveoli and pulmonary capillaries.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.
