Answer:
Stratified squamous epithelium
Explanation:
Most animals, including humans, have stratified squamous epithelium in their esophagus. It may include keratin, which gives an extra layer of protection, allowing them to eat bigger and less chewed food. It should be noted that the esophagus has a mucous membrane and because of the muscular layers, called muscularis mucosae, the food can pass rapidly through it preventing damages in its layers due to coarser or abrasive food.
So when one scientist turns around and says the mass of an electron is 9.10938291×10^-31 kilograms we know what a kilogram is and so we don't get an answer that it's 32949 microsmiths as he invented his own measurement because he needed one.
