- Worms use a hydrostatic skeleton to generate movement. How do they do this? a. Their bones are filled with water, which provides the weight of the skeleton. b. The change in body structure is caused by contraction of muscles compressing the watery body fluid. c. The muscles contain water vacuoles, which, when filled, provide a rigid internal structure. d. The term hydrostatic simply refers to moist environment. They generate movement just as arthropods do.arrow_forwardWhy does the larval stages of insects exhibit a softer and thinner exoskeleton than their adult forms?arrow_forwardWhat disadvantages associated with having exoskeletons did arthropods have to overcome to allow natural selection to favor this trait?
