C chemicals are the only substance that can cause dissolveing or mass burning tension with atoms in a place and a human has chemicals also in the stomach which is used to break down food
Answer:
Surfactant increases airflow. It has this effect on airflow because it reduces resistance to lung inflation. Airflow increased as predicted.
Explanation:
Pulmonary surfactant is a complex mixture of lipids and proteins secreted by the Type II alveolar cells. The major component of surfactant, dipalmitoyl-phosphatidylcholine (DPPC), is an amphiphatic phospholipid. The main function of the pulmonary surfactant is to reduce the surface tension at the air/liquid interface in the lungs by forming lining layer between the aqueous airway liquid and the inspired air. prevents alveolar and airway collapse at end-expiration and thus allows cyclic ventilation of the lungs. It decreases surface tension in the alveoli making it easier for the alveoli to increase surface area for gas exchange. By lowering alveolar surface tension, pulmonary surfactant provides two important benefits:
(1) it increases pulmonary compliance, reducing the work of inflating the lungs; and
(2) it reduces the lungs’ tendency to recoil, so they do not collapse as readily.

Explanation:
Calorie
(Calorie most specifically means the amount of energy needed to raise one gram of water by one degree celsius.)
*But in the context of nutrition, we use calorie to describe how much energy a food contains and can transfer to the body. For example, a banana has about 105 calories. The average human adult needs about 1800-2000 calories per day depending on size and activity level.
