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.

Answer:
The theory of common descent states that all living organisms are descendants of a single ancestor. Hence, common descent helps scientists better understand why species living in different geographical regions exhibit different traits. Some of these traits are highly conserved among broad animal classifications (e.g., vertebrates or tetrapods), and seemingly different species (e.g., birds and reptiles) share inherited physical and genetic traits, and successfully adapted organisms typically produce more offspring.
Explanation:
In evolutionary biology, it is theorized that a group of organisms share common descent if they have a common ancestor.
