Answer:
Nuclear transmutation
Explanation:
The process in which an element spontaneously transforms into another isotope of the same element, or into a different element is called nuclear transumutation. It occurs when the number of protons or neutrons in the nucleus of an atom is changed.
Cells need energy to carry out processes like mutation, reproduction and for mobility. The basic source of energy is glucose. If one factor prevents the cell from taking in the source of energy, then one possibility is the cell will weaken, unable to carry out processes and eventually will die.
