Answer:
<u><em>"Any form of exercise or activity that uses the aerobic metabolism"</em></u>
Explanation:
- Aerobic exercise is more commonly known as "cardio" or "endurance exercise".
The thing that makes an exercise aerobic is when oxygen is heavily involved in the cellular reactions that provide the body with energy.
Aerobic exercises make the heart more efficient and capable of moving more oxygen-carrying blood.
A half life is the amount of time it takes for half of an isotope to decay in a given sample. The half life of carbon 14 (which is an isotope) is 5730 years. Carbon-14 is present in many fossils, hence scientists use this to figure out the age of fossils, this specific usage is called carbon dating.
