question 14

Explanation:

For Question 12: The sensory area in the brain is responsible for projecting a sensation. The receptor detects stimuli, the sensory neuron transmits the signal, and the sensory tract is a bundle of neurons. But the actual projection (perception) of the sensation occurs in the sensory area of the brain.
For Question 13: For taste, chemicals must dissolve in saliva (a body fluid). For smell, chemicals (odorants) bind to olfactory receptors in the nasal cavity. However, they still need to be in a fluid - like environment (mucus in the nasal cavity) to interact with the receptors. So, it is false that it is not necessary for smell - associated chemicals to be in a body - like fluid.

Answer:

Question 12: sensory area in the brain
Question 13: False
