Ples help is it Fission, Fusion, or Both 1. Incredibly high amounts of energy are released. 2. Results in a nuclear change. 3. The end product is heavier. 4. Two nuclei become one. 5. The end product is lighter.

1. fission

2. both

3. fusion

4. fusion

5. fission

Explanation:

Fission refers to the splitting of a single nucleus into two or more small nuclei while fusion refers to the combination of two or more small nuclei into one heavy nucleus.

When a single heavy nucleus splits, energy is released and the end products are 2 or more lighter nuclei. On the other hand, when several light nuclei fuse into one nucleus, energy is absorbed and the end product is one heavy nucleus. Both fission and fusion result in a nuclear change.
