O Making new red blood cells via bone marrow
O The heart beating 100,000 times each day
Chewing food
O Filtering wastes through the kidneys
O Inhaling and exhaling air



Answer :

Final answer:

Chewing food is not a metabolic activity, unlike other listed processes that involve chemical reactions for energy production and bodily functions.


Explanation:

Chewing food is not a metabolic activity because it is a mechanical process that aids in food digestion but does not involve the chemical reactions necessary for metabolism. On the other hand, making new red blood cells, the heart beating, filtering wastes through the kidneys, and inhaling and exhaling air are all metabolic activities that involve various chemical reactions in the body to produce energy and maintain bodily functions.
