Questions: 1- Sensory Receptors LEARNING OBJECTIVE: Identify which sense receptor is involved in a real-life example. 〈○○○〉 Aaron begins to shiver when what type of receptor notices a change in his environment? a.) Thermoreceptor b.) Chemoreceptor c.) Mechanoreceptor d.) Osmoreceptor

The answer is the first one (or A): Thermoreceptor.

Explanation for each option: a.) Thermoreceptor: Thermoreceptors are sensory receptors that detect changes in temperature. When Aaron begins to shiver, it is because his thermoreceptors have noticed a drop in the environmental temperature, triggering a response to generate heat and maintain body temperature.

b.) Chemoreceptor: Chemoreceptors detect chemical stimuli, such as changes in the concentration of oxygen, carbon dioxide, or pH levels in the blood. They are not involved in detecting temperature changes.

c.) Mechanoreceptor: Mechanoreceptors respond to mechanical pressure or distortion, such as touch, vibration, and stretch. They are not responsible for detecting temperature changes.

d.) Osmoreceptor: Osmoreceptors detect changes in the osmotic pressure of body fluids, which is related to the concentration of solutes in the blood. They do not detect temperature changes.

Summary: Aaron begins to shiver because thermoreceptors in his body detect a change in the environmental temperature, prompting a physiological response to generate heat.
