From the trachea, air enters the, which branch out into smaller tubes called.

The correct answer is air enters the - Bronchi and smaller tubes called- Bronchioles.

Explanation:

In humans, the respiratory system includes specialized organs like nose,  the pharynx (or throat), oral cavity, larynx, the trachea, the stem bronchi.

The process of respiration starts with inhaling the air through nose and mouth which travels down to the back of your throat and windpipe called trachea. The trachea then divides into air passage tubes called bronchi which ramify within the and is known as the bronchioles.

Thus, Bronchi and bronchioles are the correct answer.

i think its control and coordinate because im pretty sure thats what tissue does and the joints are what control movement and then your skeletal/ bones provides portection. hope that .

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.
