Which of the Following was an Early Selective Advantage of a Coelom

Question

Which of the following was an early selective advantage of a coelom in animals?
A) it contributed to a hydrostatic skeleton, allowing greater range of motion
B) it was a more efficient digestive system
C) it allowed cephalization and the formation of a cerebral ganglion
D) it allowed asexual and sexual reproduction

Accepted Answer

The coelom acts as a fluid-filled cavity that can change shape but not volume, providing a hydrostatic skeleton that supports the body and allows for a greater range of motion. This was a significant evolutionary advantage for early coelomates, enabling more complex movements and body structures.
