On a particular day, denali had a temperature of -23°c at its peak and 13°c at its base. what could be the reason for this temperature difference? a.) temperature increases with an increase in altitude. b.) temperature decreases with an increase in altitude. c.) the base is close to the gulf of alaska. d.) the mountain receives lake-effect snow.

B.) Temperature decreases with an increase in altitude

The higher up you go the colder it gets.

Option (B)

Explanation:

In the layer of troposphere that extends up to a height of about 10 km from the ground surface, the temperature decreases with the increasing height.

The air molecules are very densely and tightly packed near the ground surface, as a result of which the temperature remains significantly high due to absorption of heat energy. But these air molecules are arranged in a scattered manner in the upper portion of this troposphere layer due to which the temperature remains relatively cold.

This is why Denali had experienced a temperature of -23°C at the peak and 13°C at the base.

Hence, the correct answer is option (B).

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
