Mucus protects the lining of the stomach from acidic gastric juices.
Hydrochloric acid (HCl), lipase, and pepsin come together specifically in gastric juice. Its primary purpose is to render ingested bacteria inactive, preventing infectious pathogens from entering the intestine.
Squamous epithelium, like the skin, is found in the mucosa of the mouth and the esophagus and is thought to serve as a barrier against infection.
Gastric juice makes food particles soluble, starts digestion (especially of proteins), and transforms the contents of the stomach into a semiliquid material termed chyme, laying the groundwork for subsequent small intestine digestion.
Therefore, Mucus protects the lining of the stomach from acidic gastric juices.

i believe the answer is c
Answer:
cellulose
Explanation:
cow eats grass mainly but not human.
Due to this reason, cow has cellulase enzyme that helps for digestion of grass which is not present i human.
So, cellulose is the carbohydrate present in cow bu absent in human.
A useful model of the universe should explain two key observations: the movements of celestial bodies and the nature of the universe's composition, including elements like dark energy.
Two vital observations that a model of the universe needs to explain to be considered useful include the movement of celestial bodies and the nature of the universe's composition. For instance, as our knowledge grew, so did our understanding of the movement of celestial bodies. An early model imagined Earth as the center of the universe with everything else moving in circular orbits around it. However, these models had to be updated as more observations were made, leading to a sun-centered model fitting closer to the experimental evidence.
Secondly, the nature of the universe's composition is crucial. As hypotheses in astronomy evolve, our concept of the universe's makeup has grown to accept the idea of dark energy. While there's convincing evidence that dark energy makes up the bulk of the universe, scientists still seek a thorough understanding of what dark energy is in reality.
