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:
The correct option is: B. People with these disorders exhibit a personality style that differs markedly from the expectations of their culture
Explanation:
Dissociative disorders are defined as the medical condition caused by some form of psychological stress or trauma and are characterized by breakdown or disruption of self awareness, memory, perception or identity of an individual.
Dissociative disorders includes Dissociative identity disorder, Dissociative amnesia, Dissociative fugue, Dissociative seizuresm, Depersonalization disorder.
<u>Therefore, option B. is false of dissociative disorders.</u>
The Moroccan invasion was the direct factor that caused the Songhai kingdom to fall. Many other factors such as incompetent leaders, and loads of rebellions caused this too.
