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.

Jet001 [13]

Answer: D. NE producing cell bodies are found in widespread brain regions

Explanation:

Norepinephrine (NE) is a chemical in the body that exists naturally and acts as both a neurotransmitter and a stress hormone. When the brain perceives that there has been a traumatic occurrence, it is released into the blood as a stress hormone.

Norepinephrine is produced in the inner part of the adrenal glands which also produces adrenaline.

Hence, NE is only found in inner part of the adrenal glands and the correct option is D.
