The products of nuclear fusion always include a atom and energy. many nuclear fusion reactions also include the release of a

heavier , thermal and neutron

Explanation:- Nuclear fusion is a chemical reaction in which two small nuclei combine together to form a heavier nuclei and a lot of thermal energy is released.

In the sun as the fusion of hydrogen nuclei occurs, a large amount of nuclear energy stored in the form of binding energy is transformed into thermal energy.

Example of fusion reaction occurring in sun: deuterium and tritium fuses to produces helium and a neutron and is represented as :

chromosomes carry the genetic information for organisms. also, chromatin is the thread like dna which is located in the nucleus of an organism.

b - the respond is innate and varies over time.

good luck!
