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:
Human activities cause erosion in a number of ways across the globe. Research has shown that humans are responsible for more erosion than natural processes.
1. Deforestation - it drastically causes an increase in the erosion rates as plant roots hold soil tightly that prevent erosion due to wind and water but cutting trees increases it. Plantation reduces erosions.
2. Agricultural practices have an impact on erosion rate. This promotes the likelihood of erosion, as the soil can be transported more easily due to wind and water.
3. Growing monocultures - one type of crop leads to an increase in erosion as nutrition and components of soil are drastically reduced. r
4. chemical fertilizers in agriculture can also increase soil erosion, as these chemicals damage, the flora, and fauna that live in the soil.
5. Mining/walking or biking and other practices can also contribute to erosion gradually over time. Mining exposed soil during this process.
