Why are delicate movements difficult in a hydrostatic skeleton?
A) Force tends to be transmitted equally in all directions throughout the entire fluid-filled body of the animal.
B) Force tends to be transmitted anteriorly in fluid-filled body of the animal.
C) Force tends to be transmitted posteriorly in fluid-filled body of the animal.
D) Force tends to be transmitted radially in fluid-filled body of the animal.
E) Force tends to be transmitted ventrally in fluid-filled body of the animal.
Hydrostatic Skeleton
A hydrostatic skeleton is a structure found in many soft-bodied animals, consisting of a fluid-filled cavity surrounded by muscles, providing support and facilitating movement.

Final Answer :
A
Explanation :
In a hydrostatic skeleton, the force generated by muscle contractions is transmitted through the fluid inside the body cavity, spreading out equally in all directions. This makes precise, directional movements more challenging compared to systems with rigid skeletons.
