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 think the answer to this would be:

This is because Gross Domestic Product is the measure used
to estimate the monetary value of all the finished goods and services. So when
more people are working, more products and services are created. In addition to
this, since people have work then they have income to purchase products and
services in the country.
Answer:
More, had a comparative advantage, produce more

In the previous example, the United States and Brazil were efficient when they specialized. Brazil choose to specialize in the production of bananas because it in producing it. The United States and Brazil when they specialize.
Answer:
a. Yes, provided all of the required disclosures are made clearly
Explanation:
The SEC will allow Medicine for All to issue securities so long as full disclosure and transparency is confirmed by the SEC. This would apply or fall under disclosure requirements of the SEC and also be closely related with Regulation Fair Disclosure (Reg FD) rule passed by the Securities and Exchange Commission to mitigate selective disclosure by public companies to select groups or certain professionals and shareholders
