Question

multiple - choice question
how is the hypothalamus like a thermostat in a house?
it detects temperature changes and sends signals, via the circulatory system, to the body to warm up or cool down.
it detects temperature changes and sends signals, via the nervous system, to the body to warm up or cool down.
it detects glucose changes and sends signals, via the nervous system, to the body to warm up or cool down.
it detects oxygen changes and sends signals, via the circulatory system, to the body to warm up or cool down.

Explanation:

The hypothalamus is part of the brain's regulation system for body - temperature homeostasis. It senses temperature changes and uses the nervous system to send signals for the body to adjust its temperature, similar to how a thermostat senses room temperature and signals the heating or cooling system. It doesn't detect glucose or oxygen changes to regulate body temperature, and it uses the nervous system, not the circulatory system, for this temperature - related signaling.

Answer:

It detects TEMPERATURE changes and sends signals, via the NERVOUS system, to the body to warm up or cool down.
