The Maintenance of a Constant Internal Environment in an Organism

Question

The maintenance of a constant internal environment in an organism is termed
A)positive feedback.
B)homeostasis.
C)negative feedback.
D)effector control.
E)integration.

Accepted Answer

Homeostasis refers to the ability of a living organism to maintain a stable internal environment despite changes in the external environment. This is achieved through a balance of feedback mechanisms, such as negative feedback, which works by reversing changes and bringing them back to a set point to maintain stability. Positive feedback and effector control are also involved in the regulation of homeostasis, but they do not encompass the overall concept. Integration refers to the processing and coordination of information within the body, which is necessary for maintaining homeostasis, but is not the specific term for this process.
