1. Grow and Develop: All living organisms increase in size and complexity over time. This can involve physical changes, like getting taller, or internal changes, like developing new organs or functions.

2. Reproduce: Living creatures have the ability to create new individuals of their own kind. This can be through sexual reproduction (involving two parents) or asexual reproduction (involving only one parent).

3. Respond to Stimuli: Living organisms react to changes in their environment. This could be anything from moving away from a source of heat to seeking out food or a mate.

4. Maintain Homeostasis: Living things regulate their internal environment to maintain a stable state. This includes things like controlling body temperature, water balance, and blood sugar levels.
