Bony fishes, because their lungs and bony limbs were inherited from their lobe-finned ancestors. (Coelacanth) it makes more sense that a vertebrate animal evolved from one who already was a vertebrate.
If you mean the xylem pump, then after the ATP attaches to it the water can travel trough the xylem tube and get to the stomata and through osmosis travels through the semi-permeable membrane allowing it to open and allow to get In for photosynthesis

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.
