Lac
It’s an inducible operon.
Environment:
Trp
It’s deactivated when tryptophan is present in the environment.
Lac
It’s activated when lactose is present in the environment.
Repressor protein:
Trp
It’s activated by tryptophan.
Lac
It’s inactivated by lactose.
Transcription:
Trp
Tryptophan binds to the repressor protein, activating it.
Lac
Lactose binds to the repressor protein, deactivating it.

it would be problematic if the esophagus was lined with simple squamous epithelium because it is exposed to dryness or to abrasion as a result of the presence of keratin.
<h3>What is Simple squamous epithelium?</h3>
This is the type of epithelium which are present in blood vessel and the cells of the lungs such as alveoli etc.
This type of cell is absent in the esophagus because it has the ability to get dried up or abrased as result of food substances which are taken in which may cause different complications in the body.
This is therefore the reason why the stratified squamous epithelium is responsible for the lining of the esophagus.
