As altitude increases, atmospheric pressure decreases, which means less oxygen is diffused into the blood from the lungs. for instance, at 18,000 feet you would obtain 29% less oxygen than you would at sea level. this can lead to altitude sickness, or hypoxia as it is called. imagine a mountain climber, who lives at sea level, trying to climb mount kilimanjaro for the first time. the climber is very fit so he plans to summit the 19,341 foot peak in four days, though it usually takes first-time climbers five or six days. use your knowledge of equilibrium to predict the climber’s reaction to this speedy climb, and the reaction needed to restore equilibrium. match the equations to the appropriate blanks in the sentences. make certain each sentence is complete before submitting your answer. equilibrium shifts to o2releaseequilibrium shifts to hbo2formation1. when the climber ascends the mountain before acclimating, to restore homeostasis within the body.2. as the climber rehydrates and rests at a basecamp, hemoglobin (hb) is produced, which is the body's response to the stress. as a result, .3. when the climber returns to sea level before reacclimating, to restore homeostasis within the body.4. as the climber reacclimates to sea level, hemoglobin is replaced at a lower rate, decreasing hemoglobin concentrations in the blood. as a result, .

He did not infringe upon the policy making powers that he felt the constitution gave congress. but the determination of foreign policy became preponderantly a presidential concern. when the french revolution led to a major war between france and england, washington refused to accept entirely the recommendations of either his secretary of state thomas jefferson, who was pro-french, or his secretary of the treasury alexander hamilton, who was pro-british. rather, he insisted upon a neutral course until the united states could grow stronger. which provides the best objective summary of this excerpt? president washington made a good choice when he decided not to accept the recommendations of his advisors and instead insisted that the united states stay neutral during the war between france and england as president, washington believed that the united states should remain neutral in foreign policy even though he had advisors who recommended that he take sides during the war between france and england. washington did not make policy decisions during his presidency because he did not want to interfere with the policy-making powers that the constitution gave congress. washington refused to accept entirely the recommendations of either his secretary of state thomas jefferson, who was pro-french, or his secretary of the treasury alexander hamilton, who was pro-britis
