The lungs, nose, and trachea are organs of the respiratory system. which best describes these organs?

They deliver oxygen to the blood.

Explanation:

The main function of the respiratory system is to provide oxygen to the body and to remove carbon dioxide from the body. Oxygen is transported to all ports of the body via blood vessels from the lungs. The alveolar sacs, present in the lungs, allow oxygen to be transported to the blood and carbon dioxide to be taken up.

The organs of the respiratory system include nose, pharynx, epiglottis, larynx, trachea, Bronchi, Bronchioles, alveolar sacs of the lungs.

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.
