<span>A person is able to squeeze a clothespin more times if they exercise beforehand because many body systems have been activated during the prior exercise. The respiratory system is activated providing increased oxygen to brain and other muscles. The circulatory system is activated to move blood from lungs and brain to the proper muscles. The brain has been activated to a mechanical task such as muscle movement.</span>

Answer:
The Equations sort each listed half reaction as either an oxidation or a reduction.
Fe + CuSO4 + → FeSO4 + Cu
(Fe oxidized, Cu reduced)
Explanation:
For proper understanding of the concept of the Redox reaction, let us know the meaning:
Reduction- Oxidation or "redox" reactions occur when elements in a chemical reaction gain or lose electrons. This reaction causes an increase or decrease in oxidation numbers. The Half Equation Method is used to balance these reactions. The equation is separated into two half-equations, one for oxidation and one for reduction. For Example -
CuO + H2 → Cu +H2O.
In this redox reaction, CuO is getting reduced to Cu since Oxygen is getting removed.
Fe(s) + CuSO4(aq) → FeSO4(aq) + Cu(s) Oxidation state of Fe changes from 0 to +2 and oxidation state of Cu changes from +2 to 0.
