Which statements describe ways that nuclear fission is different than nuclear fusion? Select the two correct answers.

The given question lacks the choices that are essential to answer, however, the concerned part is as follow:  

Nuclear fission is used to produce electricity at nuclear power plants.  Nuclear fission involves one large atom splitting into two smaller atoms.  Nuclear fission takes place in the nucleus of an atom.  Nuclear fission releases a huge amount of energy

Nuclear fission is different than nuclear fusion are -

Nuclear fission is used to produce electricity at nuclear power plants.  Nuclear fission involves one large atom splitting into two smaller atoms.

Nuclear reactions are of two types; nuclear fusion and nuclear fission:

These processes occur in the nucleus of an atom.In nuclear fission a heavy and unstable nuclear splits into two parts to produce very high energy.in nuclear fusion, two small and unstable nuclei fuse and produce a very high amount of energy higher than nuclear fusionNuclear fission is used in producing electricity at nuclear plants.

Thus, Nuclear fission is different than nuclear fusion are -

Nuclear fission is used to produce electricity at nuclear power plants.  Nuclear fission involves one large atom splitting into two smaller atoms.
