Question

8. 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. What special sense(s) will be impacted by this mutation? The stereocilia on "hair cells" become stiffer as Vertebrates age. Which special senses are likely to be impacted by this change? Describe one specific example of how the perception of a stimulus will change due to this age related stiffening.

Explanation / Answer

8 .Ans.When mutation produces a non functional ligand gated channel which normally binds glucose,this will result in unregulated secretion of insulin and profound hypoglycemia.

Ans:In the inner ear of numerous animals, stereocilia form the sensory organelles of hair cells responding to fluid motion , including hearing and balance. Upon ageing, the stiff bundle of stereocilia can cause deafness and in turn create balance problems for an individual.
