Are based on a universal genetic code.

Reproduce.

Grow and develop.

Respond to their environments.

Change over time (engage in adaptation and evolution)

Homeostasis

A tendency to maintain a balanced or constant internal state; the regulation of any aspect of body chemistry, such as blood glucose, around a particular level

Growth: increase in size/function

Development: increase in capability or function
