I think it is 25℅ for multiple reason
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.

B) American colonists like Samuel Adams and George Washington who fought for independence from Britain.
Answer:
Abraham
Explanation:
According to the Torah, Yahweh guided Abraham and his family on a journey to the promised land of Canaan around 4000 years ago. Throughout the year, Abraham and his family keep extending their family trees and populate the area. Which is why there is a conception that Israelis can track their ancestry back to Abraham.
Historians on the other hand have different opinion regarding this conception. They believed that the population process is much complicated since they have to consider the immigration that occurred from middle east and European regions into Israel. So, not all of Israelis might have a direct ancestry to Abraham.
