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. (Simon, Reece, & Dickey, (2010), p. 4). 2. Regulation- the environment outside of an organism can change but the organism is able to internally adjust to maintain or regulate appropriate levels for survival. (Simon, Reece, & Dickey, (2010), p. 4). 3. Growth and development- the information provided by genetics which determines the growth and development patterns of an organism. (Simon, Reece, & Dickey, (2010), p. 4). 4. Energy utilization- the energy an organism takes in to use in preforming life activities. (Simon, Reece, & Dickey, (2010), p. 4). 5. Response to the environment- the response of a living organism to its environment. (Simon, Reece, &...
