Which term encompasses reproduction, metabolism, heredity, and adaptation through evolution?

• A. Tools of Science
• B. Qualitative Observation
• C. Quantitative Observation
• D. Characteristics of Life

Answer: (D)

Living things are defined by a set of features that together distinguish them from nonliving matter. Reproduction allows organisms to pass on genetic information to offspring, ensuring the continuation of a species. Metabolism includes all the chemical reactions that transform energy and matter to fuel growth, maintenance, and activity. Heredity is the storage and transmission of genetic information—typically DNA—so traits are inherited by the next generation. Adaptation through evolution means populations change over time in response to environmental pressures, leading to traits that improve survival and reproduction.

Because these processes collectively describe what it means for something to be alive, the term that best fits all four aspects is the characteristics of life. Other options describe scientific methods or ways of observing data, which do not inherently capture the biological properties that define living organisms.
