biológica

Biológica is the feminine form of the Spanish adjective biológico, and it denotes relation to biology or to living organisms. It agrees with feminine nouns and is widely used in scientific and everyday language to describe processes, substances, or classifications associated with biology. Examples include ciencia biológica (biological science), investigación biológica (biological research), and clasificación biológica (biological classification).

Etymology and usage notes: Biológica derives from Greek bios meaning life and logia meaning study, transmitted into Romance languages through Latin. The masculine form is biológico, and the feminine form biológica is used before feminine nouns. In Portuguese, the same gendered form applies, with biológica indicating a feminine agreement in related phrases such as ciência biológica or amostra biológica.

Common contexts and examples: Biological agents (agentes biológicos) are organisms or their products capable of producing disease and are discussed in biosafety and public health. Biological samples or materials (muestras biológicas) are used in medical testing and research. The term also appears in phrases like pruebas biológicas (biological tests), investigación biológica (biological research), and función biológica (biological function). In general writing, biológica tends to modify nouns tied to life sciences, ecology, medicine, and related fields.
