Answer:

<em>The correct option is C) C-shaped cartilage rings </em>

Explanation:

The trachea is commonly known as the wind-pipe. The trachea can be described as about a 4 inch long passage from which the air travels into the bronchi and lungs. The pathway of the trachea is kept open by C- shaped cartilages which are lined all over in the trachea. The C-shaped cartilages protects as well as maintain the shape of the wind-pipe. The rigidity of the trachea arises from the C-shaped cartilages.

What components of a tossed salad will pass through the human digestive tract and be digested the least?
DochEvi [55]

Answer:

Cellulose (in the lettuce)

Explanation:

  • A tossed salad usually consists of many vegetables such as lettuce, onions, tomatoes, cucumbers, etc. and then, these vegetables have added dressings which can be of different types.
  • When a person eats a tossed salad then the lettuce will be least digested as it is composed mainly of cellulose and the human body is incapable of digesting cellulose.
  • The inability to digest cellulose by human beings is because there are beta acetal linkages present in the cellulose and human beings lack the enzymes that can break the linkage.
  • However, the undigested cellulose aids in the process of digestion as it acts like fiber and thus, the process of digestion can take place smoothly.
  • Thus, the intake of cellulose-rich foods is also essential.
