Experiments with genetically altered mice showed that the mice would consume abnormally high amounts of bitter-tasting compounds in water after their ________.

#Unit 7. System Physiology – Animal
  1. hormone receptors for digestive hormones were reduced or eliminated, showing that bitter tastes are reinforced by digestive responses
  2. salt-taste cells were altered to express receptors for bitter tastants, suggesting that animals have unregulated salt appetites
  3. visual sense was reduced or eliminated, suggesting that mice learn visual cues about bitter tastes
  4. sweet-taste cells were altered to express receptors for bitter tastants, suggesting that the sensation of taste depends only on which taste cell is stimulated
