What is a possible eDuring exercise, sensory receptors detect changes in oxygen and carbon dioxide levels in the blood. This inf
ormation is then sent to the brain's medulla, which causes the heart to beat faster and increases the rate of breathing. Exercising also causes the nervous system to signal the pancreas and thyroid gland to release hormones which regulate metabolism. Which statement is best demonstrated by this scenario?

Exercise is important for the body to function properly.
Explanation:
Exercise helps a person to maintain the oxygen amounts in the body. Exercise, as such, enhances and regulates almost every system of the body including the nervous, respiratory, circulatory and hormonal systems.
The sympathetic division of the autonomic nervous system controls the physical activities in a person's body by detecting the low levels of oxygen and increasing amounts of carbon dioxide in the body.
The fossil record indicates that the earliest hominids most likely originated in "Africa," since this is the location from which humans eventually migrated to other locations.
