A is true because changes in the body's internal environment are brought about by changes in the external environment.

B is also true because maintaining homeostasis is essential for good health, as it ensures that the body's internal environment remains stable and balanced.

C is false because many aspects of body functioning have a range of values that are considered normal, not just a single value.

D is false because a positive feedback mechanism is one in which a body function is increased then increased further, not decreased.

E is false because a negative feedback mechanism is one in which a body function is decreased then brought back to normal, not always decreased.

F is false because both negative and positive feedback mechanisms require control systems to prevent the body function from becoming too extreme, not just negative feedback mechanisms.
