Kathryn ate a bag of salty chips. what allowed her brain to register the flavor of the chips? 1.smelling the scent of the salt and oils 2.transduction occurring from the taste buds 3.the chemical process of saliva breaking down food 4.anticipating the flavor of the chips

Option 2, transduction occurring from the taste buds

Explanation:

The taste buds on the tongue have specific taste receivers which are able to send sensation to the brain thereby allowing it to perceive the taste.

There are specific chemical stimulation that represents a certain taste for example -

Sweet taste is represented by sugars

Salty taste is represented by sodium chloride and other salts

Umami taste is represented by amino acid

Sour taste is represented by acid

Bitter taste is represented by alkaloids

These chemical simulator stimulates the sensory neuron through which brain perceives the taste.

Hence, option 2 is correct.
