Answer: 2 - The nucleus of an atom is split apart
Explanation: Any reaction involving the nucleus of an atom is called a nuclear reaction. It is different from ordinary chemical reactions that involve electrons because it involves the release of large amount of energy. Nuclear reactions can be classified as nuclear fission and nuclear fusion.
A nuclear reaction in which a nucleus of an atom is split into two smaller atoms with a release of large amount of energy is called nuclear fission. A nuclear reaction that involves the combination of lighter nuclei of elements to form heavier atoms that are more stable with the release of a large quantity of energy is called nuclear fusion.
B.
The radiation present is likely to cause genetic mutations.
Production of the mature sperm cells have 4 step process beginning at puberty and throughout the male's lifetime. Spermiogenesis is the final process for production of sperm where the spermatids mature into motile spermatozoa. For humans, the spermatogenesis takes 74 days to 120 days and if the transport on the ductal system is included it would take 3 months.
