Some jellyfish have skeletons that are formed by fluid-filled compartments. this fluid resists compression and thus supports the body structure from deforming. which term describes these skeletons? a. fluid skeletons b. hydrostatic skeletons c. exoskeleton d. endoskeleton

B. Hydrostatic skeletons

Explanation:

B. Hydrostatic skeletons

Explanation:

A hydrostatic skeleton is a fluid-filled skeleton that is present in many invertebrates that have soft bodies. Some of the jelly fishes are among them. The hydrostatic skeleton of jelly fishes can be compressed as it is filled with fluid.

However, it can regain the original shape once the pressure is removed. The ability of hydrostatic skeleton to be compressed and to regain the original shape help these jellyfishes to resist deformation of the body.  

materials water oxygen those are the things i can think of in this moment.

desert perennials often survive by remaining dormant during dry periods of the year, then springing to life when water becomes available. most annual desert plants germinate only after heavy seasonal rain, then complete their reproductive cycle very quickly.
