Part II: Characteristics of Living Organisms – Seven characteristics distinguish an object or thing from an actual living organism. All seven characteristics must be present simultaneously for something to be considered living. Fill in the remaining characteristics in the following table.

Characteristics of a Living Organism
1. Order – exhibit complex but ordered organization.
2. Regulation- The environment outside an organism may change drastically, but the organism can adjust its internal environment, keeping it within appropriate limits.
3. Growth and development- Information carried by genes controls the pattern of growth and development in all organisms.
4. Energy utilization- Organisms take in energy and use it to perform all of life’s activities.
5. Response to the environment- All organisms respond to environmental stimuli.
6. Reproduction-Organisms reproduce their own kind.
7. Evolution- Reproduction underlies the capacity of populations to change (evolve) over time.

Part III: Write a 200- to 300-word explanation of how atoms make up organic compounds, which make up all living organisms, addressing all three domains.
