Nuclear fusion and fission releases tremendous amount of energy using radioactive material as a fuel.
Fusion and fission are similar in that they both release large amounts of energy.
Nuclear fusion is a process in which two nuclei join to form a larger nucleus.
Nuclear fission is a process in which a nucleus splits into two smaller nuclei.
At first sight, it doesn’t make sense that both fission and fusion release energy.
The key is in how tightly the nucleons are held together in a nucleus. If a nuclear reaction produces nuclei that are more tightly bound than the originals, then the excess energy will be released.
It turns out that the most tightly bound atomic nuclei are around the size of iron-56.
Thus, if you split a nucleus that is much larger than iron into smaller fragments, you will release energy because the smaller fragments are at a lower energy than the original nucleus.
If instead you fuse very light nuclei to get bigger products, energy is again released because the nucleons in the products are more tightly bound than in the original nuclei.

Answer: C) They both result in products that have less mass than the reactants
Explanation:
Running the lid of a tight-fitting jar under hot water causes it to expand due to thermal expansion, which makes it easier to remove from the jar.
When the lid of a tight-fitting jar is run under hot water, it undergoes thermal expansion due to the increase in temperature. The expansion of the lid causes it to slightly loosen, making it easier to remove from the jar. This happens because metals have higher coefficients of expansion than glass, so the lid expands more than the jar itself.

The body of every organism is made up of the Genes. Which determines the entire life of our every organism.
Genes are actually made up of the DNA. Genes are the functional unit and basic physical unit of the heredity.
Genes generally contains DNA which actually is different for different people but same as their parents which is a unique Physical features.
Hence The body of every organism is made up of the Genes. Which determines the entire life of our every organism.
