Suggest and explain why a sprinter can use mainly anaerobic respiration during the race, while a marathon runner needs to use aerobic respiration.

Sprinter hold their breath while marathon runner didn't.

Explanation:

A sprinter can use mainly anaerobic respiration during  the race because a sprinters hold their breath during a race so due to lack of oxygen it takes energy from anaerobic respiration, while a marathon runner needs to use aerobic respiration because he use oxygen during their race and by using oxygen aerobic respiration is executed. So we can conclude that sprinters use anaerobic respiration while marathon runner use aerobic respiration during running.

enhanced global partnerships and exploration capabilities may advance international preparedness for protecting the earth from catastrophic events such as some asteroid strikes, advancing collaborative research on space weather and protecting spacecraft by developing new means for space debris removal.

the sun's light combined with the visible wavelenghts form what is called ultraviolet radiation, which are the long waves at the end of a visible light sprectrum.
