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.

The human population has changed since it first appeared on earth as The b. population has generally increased, and at rates that have varied over time.

Humans, as well as other populations, have changed since their appearance on earth. Some populations became extinct as they were not able to cope with the environmental changes whereas other became more adaptable and increased in number over time.

The human population has also increased with the passage of time. However, the increase in the rate of the human population was not a stable one. At some times in the past, the population number declined due to environmental factors such as the eruption of a disease etc.

However, with the passage of time, humans have managed to adapt themselves to the changing environmental conditions and their population is increasing rapidly.
