In the circular flow model, the market economy creates continuous, repetitive flows of goods and services, resources and money. In this model, households spend income in the product market. According to the circular flow model, households buy the goods and services that businesses make available in the product market. Moreover, In the circular flow model, businesses will buy resources from and sell products to households and other businesses. In this way: The function of businesses in the circular flow model is purchase resources and sell products.
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.
Depends on where you’re talking about. For example in Europe, Christopher Columbus was funded money after asking Queen Isabella. He told her about all the he would bring back to the country. So using that information, they would most likely request funding from royalty or people of high social classes.
