Answer:
Endocytosis is a form of active transport hence require enegry powered by ATP. The amoeba needs to change shape and engulf and envaginate the particle and then use vessicle transportation to get the materials into the cell. This requires that the cytoskeleton - composed of tubules and filaments - contracts and relax accordingly. This requires energy by ATPs just like the myosin and actin of muscle.
Phagocytosis, another form of endocytosis, is used by some cells such as immune cells to engulf foreign material and then destroy them by use of lysozymes. This is how phagocytes protect the body from invaders.

Answer:
The correct answer is the third statement.
Explanation:
To hold the bodies together, to keep them incline, and to permit for movement, all the animals require support structures. There are three kinds of support systems found in animals, that is, exoskeleton, hydrostatic skeleton, and the endoskeleton. Of the mentioned support systems, the hydrostatic skeleton is used by worms for movement.
In the worms, a fluid-filled cavity known as coelom, and the fluid known as coelomic fluid is found between the muscles and the digestive tract. This coelomic fluid works as a hydrostatic skeleton. In worms, movement takes place by contraction of muscles that compress the coelomic fluid, that is, the watery body fluid resulting in the change in body composition.
