There are 7 characteristics of life: 1. Organization - Living things have cells organized into tissues, organs, and organ systems. 2. Homeostasis - Organisms maintain internal conditions like temperature and pH within a narrow range. 3. Metabolism - Living things undergo chemical reactions and exchanges with the environment. 4. Reproduction - Organisms reproduce through processes like cell division or sexual reproduction to pass genes to offspring. 5. Growth and development - Genes direct cellular growth and development ensuring offspring resemble parents. 6. Response to stimuli - Organisms respond and move toward or away from stimuli like light, chemicals, and touch. 7. Evolution - Living things evolve over time to
