Because this factor normally varies, the most important variable that influences the diffusion of respiratory gases is the concentration gradient. The air in the lungs has a higher concentration of oxygen than that of oxygen-depleted blood and a lower concentration of carbon dioxide. This concentration gradient allows for gas exchange during respiration.
Gas exchange during respiration occurs primarily through diffusion. Diffusion is a process in which transport is driven by a concentration gradient. Gas molecules move from a region of higher concentration to a region of low concentration. Blood that is low in oxygen concentration and high in carbon dioxide concentration undergoes gas exchange with air in the lungs.
Ventilation maintains concentration gradients of oxygen and carbon dioxide between the air in the alveoli and blood flowing in adjacent capillaries.

Answer:
I believe the answer would be D) Indian ocean.
Explanation:
The Indian Ocean lies between the continents of Africa, Asia, and Australia.
Here's a nice little image of some arrows I drew on a map to show that it is indeed south of Asia and between Africa and Australia:

2. B. An emergency room is not a total institution.
Explanation:
1. According to symbolic interactionism we encounter numeorous agents of socialization in our lives, the first one, is the family. For a child, the family is where socialization begins. School is the second agent of socialization, where the child begins to interact with other people outside the family, with peers and learn a different set of rules. Mass media, including TV, is also an important agent of socialization, where the child learns about other people and other realities, mass media holds a strong influence in a person's preferences and opinions.
2. According to Erving Goffman, a total institution is an institution that is closed and separated from the outside world, people who live in total institutions do all of their daily activities in there and they are rarely allowed to interact with the outside world. Goffman did observation in prisons and in psychiatric hospitals, but a military camp also fits with the characteristics that Goffman asigned for these institutions.
