Final answer:
Olfaction, our sense of smell, is essential for survival, influencing our behaviors and perceptions based on the detection of airborne molecules.
Explanation:
Olfaction, or the sense of smell, is our ability to detect airborne molecules or odorants that enter the nasal cavity. Odorants interact with olfactory sensory neurons located in the olfactory epithelium, resulting in a pattern of neural activity that underlies our subjective experience of smell. Our sense of smell plays a crucial role in survival, influencing behaviors such as approaching food or avoiding potential dangers.
