Multiple Choice

Which example most clearly describes a system maintained by homeostasis?

A growing child will deposit new bone rapidly until the endocrine system signals the end of puberty.

During the 'fight-or-flight' response, the sympathetic nervous system causes a change in many physiological factors from increased blood pressure to decreased pain response.

Humans typically have 52 total chromosomes, 26 from inherited from their biological mother and 26 from their biological father.

Blood osmolality is maintained by the kidneys in a range from about 290 to 300 mOsm/kg.

Verified step by step guidance

Understand the concept of homeostasis: Homeostasis refers to the body's ability to maintain a stable internal environment despite changes in external conditions. It involves various physiological processes that regulate factors such as temperature, pH, and solute concentrations.

Identify the key characteristic of homeostasis: A system maintained by homeostasis typically involves regulation within a narrow range, with mechanisms in place to correct deviations from this range.

Analyze each example provided: Consider whether each example describes a process that involves maintaining a stable internal environment through regulatory mechanisms.

Evaluate the example of blood osmolality: Blood osmolality refers to the concentration of solutes in the blood. The kidneys play a crucial role in maintaining blood osmolality within a specific range (290 to 300 mOsm/kg) by adjusting the excretion of water and solutes.

Conclude why blood osmolality is an example of homeostasis: The regulation of blood osmolality by the kidneys exemplifies homeostasis because it involves maintaining a stable internal environment through precise physiological control mechanisms.
