Echinoderms' radial symmetry enables which of the following?
A) An unusually rapid nutrient uptake
B) A greatly reduced metabolism
C) Rapid adaptation to extremes of temperature
D) An unusually long lifespan
E) The ability to respond effectively in every direction of their surrounding environment
Radial Symmetry
A symmetry in which body parts are arranged around a central axis, so that any vertical cut through the axis results in identical halves, common in many invertebrates.
Nutrient Uptake
The process by which organisms obtain nutrients from their environment, essential for growth and maintenance.

Final Answer :
E
Explanation :
Echinoderms' radial symmetry allows them to respond effectively to stimuli from any direction in their environment, as their body structure is organized around a central axis. This means they can detect and react to changes or threats coming from any direction without needing to orient themselves towards the stimulus first.
