In nuclear physics, nuclear fission is either a nuclear reaction or a radioactive decay process in which the nucleus of an atom splits into smaller parts (lighter nuclei). The fission process often produces free neutrons and releases a very large amount of energy.

Thus, The Nuclear Fission is caused by the impact of Neutrons.

Gitanjali Rao, an 11-year-old Indian-American schoolgirl, was named as "America’s top young scientist" for inventing a cost-effective, quick lead-contamination detector in water. The seventh-grade student was inspired by the large-scale lead contamination in water in Flint, Michigan, that came to light recently.

Metabolism (from Greek: μεταβολή metabolē, "change") is the set of life-sustaining chemical transformations within the cells of organisms. The three main purposes of metabolism are the conversion of food/fuel to energy to run cellular processes, the conversion of food/fuel to building blocks for proteins, lipids, nucleic acids, and some carbohydrates, and the elimination of nitrogenous wastes.

In brief, the chemical processes that occur within a living organism in order to maintain life is called metabolism.

Sound is a mechanical vibration and needs a medium for propagation. The higher the density of the medium, the faster the sound travels. So, sound cannot travel through vacuum.

As the sound travels faster in solids than liquids and gases, sound travels faster in the glass than Air and water.

Yeah, its your AGE which always goes up but sadly never comes down.
