- 4. Use what you know about the anatomy and physiology of special sensory organs to evaluate how each of the following changes will impact an Animal's ability to sense its environment. A mutation produces a non-functional ligand-gated channel, which normally binds glucose. Which special sense(s) will be impacted by this mutation? The stereocilia on "hair cells" become stiffer as Vertebrates age. Identify the senses that will be impacted by this change; then, describe one specific example of how the perception of a stimulus will change due to this age related stiffening.2. List the different types of general sense stimuli. Discuss the structural and functional classification of sensory receptors and the different stimuli that each receptor detects.32.Enumerates five sensory receptors? thanks asap
