Description of a blue shark
Westkost [7]

The aerodynamic shape and lightness of the blue shark body allow it to move “elegantly” across the oceans. It exhibits countershading like many other sharks. The upper part is an indigo blue tone while the ventral and the sides are white.

It has a long caudal heterocercal fin. The second dorsal fin measures almost half the size of the first and its pectoral fins are unusually long compared to other sharks. Its eyes are large, its teeth are triangular, and it has a conical snout.

It reaches a length ranging from 3.8 to 4 meters and weighs about 240 kilograms. This species presents slight sexual dimorphism since the female tends to measure little more than 1 meter in comparison with the male.

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.
