Chapter 1 - Section 1.1 - The Characteristics of Life - Biology Matters - Page 6: 2


Homeostasis - same state or the process of maintaining the constant stable internal body environment. Organization - an assembly composed of cell/s Metabolism - the conversion of food chemicals to energy in order to sustain life Growth - gradual increase in size or stage of development Adaptation - the ability to respond to the environment Response to Stimuli - the capability of living things to change rapidly in an environment Reproduction - fundamental feature of life, the biological process of an organism to produce an offspring.

Work Step by Step

Homeostasis - Internal regulation of the environment to maintain a constant, balanced state. Organization - Being structurally composed of one or more cells Metabolism - Transformation of energy by converting chemicals and energy into cellular components (anabolism) and decomposing organic matter (catabolism). Growth - Maintenance of a higher rate of anabolism than catabolism Adaptation - The ability to change over time in response to the environment. Response to Stimuli - A living organism must be able to respond appropriately to external/environmental stimuli Reproduction - The ability to produce new individual organisms, either asexually from a single parent organism, or sexually from two parent organisms.
