Answer:Most houses were made of brick. The banks of the Nile provided the mud used to make bricks . Brick makers collected mud, added straw and water to it as needed, and stomped it with their feet until it reached the right consistency.
Explanation:
According to W.F. Ogburn and his seminal work from 1922 called”
Social Change” that would be the cultural lag. Cultural lag happens when
society can’t adapt to the fast and rapidly improving technological innovations
which unfortunately can cause a series of social problems that can be difficult
to solve.
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.
