Answer:
belief in the afterlife.
Explanation:
Archaeologists have noticed that burying the dead in the ground has been a very old tradition but a special feature added to it during the river valley civilization was that some necessary items of daily life had been added to the grave to help them in their next life. We notice these practices among Sumerians, Mayans, and Harappans. Some historians also believed that underground burials the faith in the next world lies under the Earth and underground burials provide easy access to them.

This semester, you have an assignment in which data collected from a previous assignment is included in the new project. Yes, we need to cite this information because it is academic practice to cite the previous work you have done.
In another instance, although you credited your sources and wrote a research paper, you forgot to record the page numbers for the in-text citations. You insert page numbers without double-checking them because the project is due in few hours. You cited someone, but you did so improperly, thus this is also a violation.
Following the right academic practice, while one submits their works, is essential as per the ethics.

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.
