Prior to the disaster, the climbers started to complain of fatigue, dizziness, lack of sleep, persistent headache, and impaired
motor function. These are symptoms commonly associated with Acute Mountain Sickness (AMS). AMS is caused by not having enough oxygen. At high elevation, there is less oxygen available to the body because ______________. Individuals who live at high altitudes (rather than just visiting them) _________ suffer from AMS at the altitude in which they live. a. the overall atmospheric pressure is lower so the partial pressure of oxygen is also lower, would not
b. oxygen make up a smaller percentage of the air, would
c. oxygen makes up a smaller percentage of the air, would not
d. the overall atmospheric pressure is lower so the partial pressure of oxypen is also lower, would
a. the overall atmospheric pressure is lower so the partial pressure of oxygen is also lower, would not
Explanation:
As an individual rises higher on a mountain, he will experience a situation where the air becomes increasingly thin. This means that the oxygen density becomes reduced each time the altitude becomes higher, this reduction in air causes a lower atmosphere pressure, since the pressure of the oxygen gas is also low, which makes breathing difficult and can cause Acute Mountain Sickness' symptoms. However, people who already live in high attitudes, have their bodies adapted to this situation, which means that they do not suffer from these symptoms.
According to distraction-conflict theory, being aware of another person's presence divides our attention between this person and the task at hand. This division of attention is arousing, which explains why people perform better on well-learned tasks in the presence of others.
Citizens were provoked by plans to cut public spending and raise taxes as austerity measures in exchange for a €110 billion bail-out, aimed at solving the Greek government-debt crisis at the time. So the correct answer is D.
