A healthy college student went to Colorado at the end of the school year for a vacation. While there, he drove to the top of Pike's Peak, a tall mountain. During his first hour on the peak, he walked about but had to sit down to rest three times. The last time was in the weather station. He glanced at the barometer hanging over his head. It read 450 mm Hg. (total Atm pressure). Explain two physiological responses that would increase the amount of oxygen delivered to her tissues.

Due to sloppy geography and lower air pressure.

Explanation:

Walking on the sloppy and low pressure are the two physiological responses that increases the amount of oxygen given to her tissues. Walking on the steep and sloppy region requires high amount of energy so for that energy the body needs more and quick oxygen in order to breakdown of glucose for the release of energy that can be used for walking while on the other hand, the low atmospheric pressure have low amount of oxygen in the air so the person needs more oxygen for its breathing so the person breathe air fastly to supply optimum amount of oxygen to the body.

lunar landing mission. apollo 11 was the first manned mission to land on the moon. the first steps by humans on another planetary body were taken by neil armstrong and buzz aldrin on july 20, 1969. the astronauts also returned to earth the first samples from another planetary body.
