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.
One of the primary reasons that one individual is faster in a 50-meter sprint than another is a. a greater number of muscle fibers of smaller diameter. b. more oxidative fibers in the lower limb muscles. c. an enhanced ability to deliver oxygen to the muscles. d. a greater percentage of fast-twitch fibers in the lower limb muscles.
