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.

<u>Rules- </u>
There are many ways that people can influence our behavior, but perhaps one of the most important is that the presence of others seems to set up expectations
We do not expect people to behave randomly but to behave in certain ways in particular situations. Each social situation entails its own particular set of expectations about the “proper” way to behave. Such expectations can vary from group to group.
One way in which these expectations become apparent is when we look at the roles that people play in society.
<u>Norms- </u>Social norms are the unwritten rules of beliefs, attitudes, and behaviors that are considered acceptable in a particular social group or culture. Norms provide us with an expected idea of how to behave, and function to provide order and predictability in society. For example, we expect students to arrive to a lesson on time and complete their work.
The idea of norms provides a key to understanding social influence in general and conformity in particular. Social norms are the accepted standards of behavior of social groups.
These groups range from friendship and workgroups to nation-states. behavior which fulfills these norms is called conformity, and most of the time roles and norms are powerful ways of understanding and predicting what people will do.
There are norms defining appropriate behavior for every social group. For example, students, neighbors and patients in a hospital are all aware of the norms governing behavior. And as the individual moves from one group to another, their behavior changes accordingly.
Norms provide order in society. It is difficult to see how human society could operate without social norms. Human beings need norms to guide and direct their behavior, to provide order and predictability in social relationships and to make sense of and understanding of each other’s actions. These are some of the reasons why most people, most of the time, conform to social norms.
Answer: This is an example of problem-focused behavior coping.
Explanation: When a problem arises in day-to-day life, irrespective of at work or at home, the behavior tends to change and may bring prolonged sadness. To cope up with this behavior knowing full well that it may cause loss, the problem, not the feelings, needs to be focused in order to find out solid solutions to it. This approach is thus called a problem-focused behavior coping approach.
The answer in this question is that the research has shown that women who were exposed to the flu virus during her first trimester of pregnancy had a sevenfold increased risk of bearing a child who later developed schizophrenia. Schizophrenia is defined as a mental disorder by abnormal social behavior and failure to understand what is real.
