The aorta is the body's main artery therefore that makes the aorta the main supply of pressure to make the blood flow.

Answer:
The correct answer will be option-C
Explanation:
In an organism, the mechanism of gas exchange depends on the partial pressure and total pressure of the gas. Partial pressure is the pressure of the gas exerted by a single type of gas in a mixture of gases and this pressure determines the movement of gases in the system.
The diffusion of the oxygen from the alveoli to blood capillaries depends on the partial pressure as the partial pressure of oxygen is high in alveoli measured about 104 mmHg compared to the capillaries measured about 40 mmHg.
This difference in the pressure generates pressure gradient which leads to the movement of the oxygen from alveoli to the capillaries as the movement takes place from higher to lower concentration gradient.
Thus, Option-C is the correct answer.
Answer:
I would say that the best answer to the question: What is the dependent variable of this research, would be: A) Information alone is not sufficient if people are not motivated to use it.
Explanation:
A dependent variable is the one in research whose result will entirely depend on the outcomes of the independent variables. In this case researchers decided to use different means of information on smoking to achieve the reduction of their smoking. While to a group they showed them a video and gave them a pamphelt with instructional information on how to quit, to the other group they subdivided it and gave one portion just the video, and the other just the pamphlet. In the end, the result was that during follow-up, researchers found that the group with the least reduction in smoking was the one to whom only the pamphlet had been given. This result showed that the pamphlet, which was the information only, was not enough to encourage smokers to leave the habit. It became evident that a factor of fear was necessary to achieve that final goal.
