Which prefix pertains to life?

The prefix that pertains to life is "bi/o." This prefix is derived from the Greek word "bios," which means "life." It is commonly used in medical terminology, particularly in terms that describe living organisms or biological processes. For instance, "biology" is the study of life, and "biopsy" refers to the examination of living tissue.

In contrast, the other prefixes do not relate directly to the concept of life. "Aut/o" refers to self, "adip/o" pertains to fat, and "caus/o" relates to causation or the act of causing. Understanding these prefixes helps in grasping the foundational terminology used in the medical field, particularly when coding and interpreting patient diagnoses and procedures.
