Hello there!
Seeking shelter from the cold is an example of Response to Temperature.
This all started with something called Negative Feedback which is a reaction that causing a return to Homeostasis. An example of a negative feedback is thermoregulation of someone's in a situation of being too cold. Thermoreceptors in your skin which are the receptors, send the information that the person is too cold to the Hypothalamus which is the control center. The control center analyzes the information and sends signals through the nervous system to the blood vessels, which are the effectors. Then Vasoconstriction occurs by causing the person to gain heat and return to homeostasis.
Thus, when your body is cold and you are looking for shelter or a blanket or whatever, your body is telling you that. That's how you know if you are too cold or not. This all happened with the three components of the negative feedback, which are the receptors, control center, and the effectors.
As always, it is my pleasure to help students like you.
