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.
I’m sorry I really don’t know I just wanted the points
Answer:
Qualitative
Explanation:
According to my research on different research approaches, I can say that based on the information provided within the question this type of data gathering can be referred to as a qualitative approach to describing behavior. Qualitative refers to the process of focusing more on quality as opposed to focusing more on the quantity.

Answer:
The answer is technical analysis.
Explanation:
Technical analysis refers to the evaluation of a security's available data, which allows to predict future outcomes based on statistics. Some of the most common points of reference are the changes in the price of a given security, as well as its past trading activity.
