Question

Quizplus · Accepted Answer

In animals with hydrostatic skeletons, such as earthworms and cnidarians, the body is filled with a fluid that provides support and structure. The circular and longitudinal muscles help to control the movement and shape of the body, but they do not function as the supportive component of the skeleton. The body wall also helps to provide some support, but it is not the primary supportive component. Therefore, the correct answer is A) a fluid-filled body cavity.
