Answer

Brief Explanations:

  • Question 6: Taste and smell are chemoreceptors as they respond to chemical stimuli from food. CO₂ receptors in the carotid artery are also chemoreceptors. Rod cells in the retina are photoreceptors that respond to light, not chemicals.
  • Question 7: A gymnast on a balance - beam is in contact with the beam and moving, which stimulates mechanoreceptors (respond to mechanical stimuli like touch, pressure, movement). There is no significant chemical or light - related stimulation during this routine compared to mechanical, so mechanoreceptors are involved and photoreceptors are not relevant in this context.
  • Question 8: The optic nerve is responsible for vision and the auditory nerve for hearing. If they were switched, when seeing lightning (a visual stimulus), the signal would go to the auditory part of the brain, so one would hear strange noises instead of seeing the lightning.

Answer:

    1. C. rod cells in the periphery of the retina
    1. A. mechanoreceptors and chemoreceptors
    1. C. may hear strange noises but would not see any lightning
