A characteristic or quality of an organism.

Members of the same species that live in the same geographical area; may be distinctly different from populations living elsewhere, due to the spread of local adaptations within a population

A process by which a population becomes better suited to its habitat, and in which a genetic variation that provides an advantage to survive and reproduce generally spreads through the population.

A distinct feature, behavior, or physiology of the organism that occurs to individuals within a population or species.

All of the offspring that are at the same stage of descent from a common ancestor, for example, mothers and daughters representing two separate groups.

Process of selection whereby favorable traits become more common and less favorable traits become less common in following generations.

Movement to a different geographical or climatic region where food is more available.

A slowed physiological state of an organism to survive long periods of cold temperature or reduced food supplies.

A form of artificial selection whereby deliberate breeding results in desired traits in plants or animals.

An action or condition that provokes a response.

Any behavior of a living organism that results from an external or internal stimulus.

The tendency of an organism or cell to maintain a balanced state so as to maintain health and function.

Physiological changes in the body due to a reaction to stress.

Response of a plant to grow toward or away from light.

Term	Definition
Trait	A characteristic or quality of an organism.
Population	Members of the same species that live in the same geographical area; may be distinctly different from populations living elsewhere, due to the spread of local adaptations within a population
Adaptation	A process by which a population becomes better suited to its habitat, and in which a genetic variation that provides an advantage to survive and reproduce generally spreads through the population.
Variation	A distinct feature, behavior, or physiology of the organism that occurs to individuals within a population or species.
Generation	All of the offspring that are at the same stage of descent from a common ancestor, for example, mothers and daughters representing two separate groups.
Natural Selection	Process of selection whereby favorable traits become more common and less favorable traits become less common in following generations.
Migration	Movement to a different geographical or climatic region where food is more available.
Hibernation	A slowed physiological state of an organism to survive long periods of cold temperature or reduced food supplies.
Selective Breeding	A form of artificial selection whereby deliberate breeding results in desired traits in plants or animals.
Stimulus	An action or condition that provokes a response.
Response	Any behavior of a living organism that results from an external or internal stimulus.
Homeostasis	The tendency of an organism or cell to maintain a balanced state so as to maintain health and function.
Fight or Flight	Physiological changes in the body due to a reaction to stress.
Phototropism	Response of a plant to grow toward or away from light.
