Final answer:
The ability to detect changes in the environment in humans depends on the presence of sensory receptors.
Step-by-step explanation:
In humans, the ability to detect changes in the environment depends upon the presence of sensory receptors. Senses provide information about the body and its environment. Humans have five special senses: olfaction (smell), gustation (taste), equilibrium (balance and body position), vision, and hearing. Additionally, we possess general senses, also called somatosensation, which respond to stimuli like temperature, pain, pressure, and vibration. All of these senses rely on sensory receptors to convert stimuli into electrical signals in the nervous system through a process called sensory transduction.
