- In which of these ways do coldness receptors differ from heat receptors?A. Coldness receptors respond to a change in temperature, not to the absolute temperature.B. The response of a coldness receptor grows stronger and stronger until you find a warmer place.C. Coldness receptors also respond to certain chemicals, whereas heat receptors do not.D. Coldness receptors respond only to life-threatening levels of coldarrow_forwardWhat is adaptation?arrow_forwardA behavioral physiologist is studying the homeostatic control of blood pH. In a trial, a lizard runs on a treadmill for a set amount of time and the blood pH is measured. The blood pH drops as carbon dioxide is released into the bloodstream. Which component of the homeostatic feedback system is responsible for determining if the blood pH is far enough from normal that a response is necessary?

- Describe the steps in the homeostatic feedback system activated to ensure normal body temperature is maintained when exposed to a hot external temperature (e.g., 42 degrees Celsius). Give typing answer with explanation and conclusionarrow_forwardImagine you are sick and you have fever. Sensors on the skin and brain detect this and communicate with the temperature regulatory center in the brain which then sends out a command to the sweat glands of your body as a result of which you start sweating and in about 15 mins your body temperature comes back to normal for the time being.
