Expert Solution

Step 1

1.B)Physical distortion of cells.

Mechanoreceptors are receptors that are stimulated by physical changes such as touch,vibration, distortion, etc.

2.A)An odorant molecule

Chemoreceptors are receptors that are stimulated by the changes in chemical composition of their environment such as changes in smell, taste, etc.

3.B)Thalamus

Thalamus is the information relay station in our body. All the informations from our body,except smell,must be processed through thalamus before being sent to brain for interpretation.
