Answer:
The false statement is-Our body has no mechanism to stabilize free radicals.
Explanation:
Free radicals are the atoms produced in the cell mainly due to oxidative stress. For example, oxygen splits into an atom having an unpaired electron. So these atoms having unpaired electrons are called free radicals.
Free radicals are responsible for damaging DNA and causing cancers in the body. In our cells antioxidants are present which checks the presence of free radicals in the cell.
They stop the free radicals chain reaction and eliminate the free radicals in the cell by giving an electron to free radicals without getting destabilized. Therefore our bodies have a mechanism to fight with free radicals.

<span>Heart Rate Reserve, HRR. Heart rate reserve (HRR) is the difference between resting heart rate (HR<span>rest) and maximum heart rate</span> (HRmax). Heart rate reserve is used when determining exercise heart rates. The Karvonen formula is used to calculate exercise heart rate at a given percentage training intensity.</span>
