[Campbell Biology P.1156] Based on the information presented in the diagram "What steps link ... | Practice Question

Based on the information presented in the diagram "What steps link sensory stimuli to animal activity?", which of the following pairings of sensory receptor type and its primary stimulus is INCORRECT?

  • A: Mechanoreceptors: Sound, touch, motion
  • B: Electromagnetic receptors: Light, electricity
  • C: Chemoreceptors: Heat, cold
  • D: Pain receptors: Noxious chemicals, temperatures

Explanation

The diagram clearly labels Chemoreceptors as detecting 'Solutes, tastes, smells' and Thermoreceptors as detecting 'Heat, cold'. Therefore, the pairing of 'Chemoreceptors: Heat, cold' is incorrect.
