Multiple Choice

Which of the following is true regarding the role of homeostasis in maintaining body temperature?

Homeostasis causes body temperature to fluctuate widely in response to external temperatures.

Homeostasis relies solely on the endocrine system to maintain body temperature.

Homeostasis involves the hypothalamus regulating body temperature through feedback mechanisms.

Homeostasis is only concerned with maintaining blood pH levels, not temperature.

Verified step by step guidance

Understand the concept of homeostasis: Homeostasis is the body's ability to maintain a stable internal environment despite changes in external conditions. It is crucial for the survival and proper functioning of organisms.

Identify the role of the hypothalamus: The hypothalamus is a part of the brain that plays a key role in regulating body temperature. It acts as a thermostat by detecting changes in body temperature and initiating appropriate responses to maintain a stable temperature.

Explore feedback mechanisms: Homeostasis often involves feedback mechanisms, which can be either negative or positive. In the case of body temperature regulation, negative feedback is used to counteract changes and bring the temperature back to a set point.

Evaluate the options: Consider each statement in the problem. The first option suggests wide fluctuations, which contradicts the stabilizing role of homeostasis. The second option incorrectly limits the role to the endocrine system, while the fourth option ignores temperature regulation.

Select the correct statement: The third option correctly describes the role of the hypothalamus and feedback mechanisms in maintaining body temperature, aligning with the principles of homeostasis.
