What happens to the amount of solar radiation as latitude increases?
The north pole receives more solar radiation during the summer than the equator does, but during winter, it receives no solar radiation. This means that as latitude increases, the amount of solar radiation increases in the summer and decreases in the winter.

What substance is produced anaerobically during strenuous activity?
Alcohol (and CO2), or Lactic Acid

What prevents the lungs from over expanding as one breaths more deeply during strenuous activity?
the respiratory centers
What is cardio -respiratory endurance?
the ability of the heart and lungs to pump oxygen rich blood to the muscles during strenuous activity.
How do your muscles continue to get energy during high levels of activity when there is not enough energy?
The muscles continue to get enough energy during high levels of activity when there is not enough oxygen through the absorption of water. It is a good idea to drink water frequently when doing strenuous exercise.
What can be done to prevent being sick during strenuous activities?
Do not eat 2 hours before strenuous activities.
