This control of the internal environment is called homeostasis, and can be observed through the ____________ range of the body's
Semenov [28]

Answer: "homeostatic (dynamic equilibrium) range"

Homeostasis can be observed through the "homeostatic range (pre-set limits)" of the body's pH, temperature and blood glucose.

Explanation:

Homeostasis is the control of internal environment , physical and chemical conditions maintained by the living systems. A body takes control of its internal environment in spite of external forces interruptions. It can be defined as the body's defensive mechanisms.

Homeostasis is maintained and controlled by the nervous system.

Homeostasis is for optimal functioning of the internal environment such as body pH, body temperature, fluid balance, chemical ions balance (calcium, sodium and potassium) and blood glucose.

Body temperature is normally about 37.5° C (98.6° F).

Salt concentration in body fluids is normally about 0.9%

Blood glucose is normally about 10 mg/ml.

A disturbed (imbalanced body as a result of external forces) body regains its haemostasis balance by

Activating reflexes that fight the disturbance and maintaining behaviours to counteract the disturbance.
