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: Negative punishment
Explanation: Negative punishment is use to reduce a behavior by removal of a favorable stimuli. It is a kind of punishment which focuses in reducing the rate of undesired behavior from an individual. Example is being grounded,losing access to a toy.
Answer:
Amsterdam Treaty
Explanation:
The Amsterdam Treaty was signed on 2 October 1997 according to which the Member States decided to engage in broad policy and institutional changes. The Treaty authorized member states to increase certain powers from national governments to the European Parliament, covering diverse issues like legislating on foreign and security policy, adopting civil and criminal laws and immigration laws. It paved the way for implementing institutional changes to accommodate its expansion because of the new member nations joining the EU.
he filled the senate with new members i think
<span>The answer is c. patricians.
The patricians were the aristocracy class of Rome. Initially they were
the only ones who could hold office as well as formulate the laws. This angered the commoners or plebeians who
rose in revolt. This frightened the patricians that they were grant the right
to hold office as well. Through the
creation of the Twelve Tablets of Law, it made it clear that the plebeians now
officially had the right to hold office like the patricians.</span>
