Explanation:
When iron gets in contact with oxygen (or water, which also contains oxygen) it starts giving electrons to the oxygen atoms, in a process called oxidisation, and when that occurs, iron oxide (
) is made.
Note: iron oxide is what we call rust. And, iron is so easy to rust because it usually isn't mixed with any other protective metals or covered in protective films.

A:) In cellular respiration, the carbohydrates from food are disassembled into glucose molecules. Then, this glucose is used to produce energy-rich ATP molecules. In most eukaryotic organisms, cellular respiration takes place in the mitochondria of cells.
