The document discusses the seven key characteristics of living things: 1) cellular organization; 2) reproduction; 3) metabolism; 4) homeostasis; 5) heredity; 6) evolution; and 7) interdependence. It provides examples of different lifespans among organisms and their ability to reproduce and maintain internal environments. The characteristics must be present in all living things and are important for defining what constitutes life.
