Nuclear energy is a form of energy released from the nucleus, the core of atoms, made up of protons and neutrons. This source of energy can be produced in two ways: fission – when nuclei of atoms split into several parts – or fusion – when nuclei fuse together. (IAEA, 2022. What is Nuclear Energy? The Science of Nuclear Power https://www.iaea.org/newscenter/news/what-is-nuclear-energy-the-science-of-nuclear-power)
Nucleic acids are large biomolecules that play essential roles in all cells and viruses. A major function of nucleic acids involves the storage and expression of genomic information. Deoxyribonucleic acid, or DNA, encodes the information cells need to make proteins. Nucleic acids are made of nitrogen-containing bases, phosphate groups, and sugar molecules.

The nucleolus is a spherical structure found in the cell’s nucleus whose primary function is to produce and assemble the cell’s ribosomes. (National Human Genome Research Institute, 2024. Talking Glossary of Genomic and Genetic Terms https://www.genome.gov/genetics-glossary/Nucleolus)
A nucleotide is one of the structural components, or building blocks, of DNA and RNA. A nucleotide consists of a base (one of four chemicals: adenine, thymine, guanine, and cytosine) plus a molecule of sugar and one of phosphoric acid.

A field of mass in which the isosteric and isobaric surfaces coincide is called a barotropic field. (Neumann, G.. Ocean Currents. Netherlands: Elsevier Science, 2014.)
A nucleus, as related to genomics, is the membrane-enclosed organelle within a cell that contains the chromosomes. (National Human Genome Research Institute, 2024. Talking Glossary of Genomic and Genetic Terms https://www.genome.gov/genetics-glossary/Nucleus)
Redness of skin due to the presence of increased amounts of oxygenated haemoglobin within dilated skin capillaries. It may be due to localised or generalised inflammatory processes but may result from increased cutaneous blood flow following exertion or associated with pyrexia. (WHO, 2023. ICD-11 ME64.0 Erythema https://icd.who.int/browse11/l-m/en#/http://id.who.int/icd/entity/800313204)
A synthetic chemical that when absorbed into an organism either mimics or blocks hormones and disrupts the normal functions of the organism. Known human endocrine disruptors include but are not limited to: dioxin, PCBs, DDT, and some other pesticides. (ASFA Thesaurus)
