The correct answer is - c. it encouraged written language so that records could be kept.
The development of agriculture enabled people to settle in at one place instead of having a nomadic life. This way of life and the sufficient amount of food enabled the people to focus on other things, one of which was the invention of the written language which allowed the people to be able to express themselves better, or to preserve records over time, to provoke the creativity in them...
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:
African Americans
Explanation:
The institution of slavery resulted in prosperity for large farm owners at the expense of <u>African Americans, </u>After the Civil War, many Texans continued to be denied basic rights—including the right to participate in the political process—through the use of literacy tests, grandfather clauses, poll taxes, and the so-called white Correct primary, in which only Anglos could participate. African-Americans constitute majority of slaves who work in sugar cane and cotton plantations in Texas, they were a cheap source of labour as the slave masters did not have to pay them for services. As a result of this exploitation of African American slaves, large plantation owners became wealthy.

When minority workers felt that they've been discriminated in the workplace, they can contact NAACP and asked for assistance.
After accepting the request, NAACP would provide the workers with various legal help that help them to win their case on the court and obtain compensation.
