Answer:
1. More important
2. Less important
Explanation:
I calculated it logically
All of the volatile chemicals in the nose stimulate smell receptors and it happens as follows:
The chemical senses that respond to variations in the external environment have been divided into three categories:
- Gustatory receptors or taste.
- General chemical receptors.
Smell receptors have high sensitivity and specificity to very dilute volatile substances; they are described as "chemical distance receptors".
These primary receptors are located in areas of tissue, called olfactory neuroepithelium, located in the uppermost portion of the nasal passages.
Odorous substances are volatile chemical compounds that must contact the smell receptors for the perception of odor to occur.
In relation to the classification of odors, it is taken into account that the more volatile a substance is, the more effective it is as an olfactory stimulus.
The odorous molecules are trapped and then diffuse through the mucus to bind to the cilia at the ends of the smell receptors cells.
Therefore, we can conclude that smell receptors, which respond to all of the volatile chemicals, these volatile molecules must first pass through a layer of aqueous solution, before they reach the smell receptors.
