Final answer:
Exteroceptors can process external stimuli through various types of receptors, including sound information via mechanoreceptors, light via photoreceptors, and temperature or chemical stimuli (such as taste) via thermoreceptors and chemoreceptors.
Step-by-step explanation:
Exteroceptors are sensory receptors that process stimuli from the external environment. These receptors can detect various types of stimuli, including chemical, physical, and temperature changes. Music from a radio would involve sound information, which is detected by mechanoreceptors. A blinking car taillight would involve photoreceptors in the eyes, responsible for detecting light. However, a sip of cold water represents a type of sensory input related to temperature, which is detected by thermoreceptors, as well as potential chemical stimuli for taste, which are part of the somatic and autonomic systems. Therefore, exteroceptors can process stimuli from all of the examples provided.
