the answer is 21<span>% oxygen, </span>
Answer:
The correct answer is - per gram, the marathon runner's muscles would contain more myoglobin than the sprinter's muscles.
Explanation:
Marathon runners have smaller leg muscles and thinner quads and calves as marathon runners require slow-twitch muscles while in sprinters the fast-twitch muscle requires. Slow-twitch muscles of marathon runners have more amount of myoglobin, per gram than fast-twitch muscles.
Myoglobin acts as local oxygen storage that provides oxygen to the muscles in case of less oxygen supply than required temporarily and a marathon race is an intense exercise or activity that requires more oxygen.
<span>Evaporation and transpiration.
</span>
The evaporation process uses the sun radiation or sun’s
thermal energy for vaporization of a water from the land or soil to be water
vapor then in the air. Transpiration on the other hand is the same with evaporation
that involves water molecules to be vaporized into the air but it is located in
the stoma of the plants. It is like evaporation within plants. This is actually
to have homeostasis in plants and still part of the water cycle.
