54
Q

Change in one physiological variable to counteract a change in another

A

Enantiostasis (allostasis)

55
Q

Homeostatic regulatory variable: optimal chemical or physical condition

A

Setpoint

56
Q

Homeostatic regulatory variable: actual current condition

A

Feedback information

57
Q

Homeostatic regulatory variable: discrepancy between setpoint and feedback

A

Error signal

58
Q

Homeostatic regulatory input: reduces or reverses activity of effector, reopens condition to setpoint (negative feedback, positive feedback, feedforward information)

A

Negative feedback

59
Q

Homeostatic regulatory input: amplifies activity of effector (negative feedback, positive feedback, feedforward information)

A

Positive feedback

60
Q

Homeostatic regulatory input: changes setpoint (negative feedback, positive feedback, feedforward information)

Q

Feedback effector: opposes change in variable

A

Antagonistic control

62
Q

Evolution by natural selection (adaptation, acclimatization, acclimation)

Adaptation

63
Q

Physiological, biochemical, or anatomical change within an individual from chronic exposure to a new environment (adaptation, acclimatization, acclimation)

A

Endothermic

72
Q

2 bioenergetic strategies used by animals: meaning they do not produce enough metabolic heat to have much effect on body temperature (endothermic, ectothermic)

A

Ectothermic

73
