HI there
The correct answer is : B
I hope that's help:) Please rate
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.
Answer: Comparative politics
Explanation:
Comparative politics is described as a section of political study that makes use of comparison method or empirical method to explore politics in countries.
It is the view of political experience with a into more than one country with the sole aim of making comparison.
Answer:
When you compare things, you are looking for what is an analogy. That is a proper comparison of both of them.
Explanation:
The second alternative is correct (B).
The economic matrix in force in the world is based on the burning of fossil fuels, mainly petroleum, which releases amounts of CO2 and other gases in the ozone layer.
The acid rain is due to the exaggerated amount of products from the burning of fossil fuels released into the atmosphere. That is, human activities are mainly responsible for this phenomenon of acid rain.
Thus, the change to a clean energy matrix, using solar, wind and other energy, can result in a decrease in the phenomenon of acid rain.
