An accurate contrast between radial and bilateral symmetry among animals is that

A. mirrored arrangement of body components is common with radial symmetry, but not found at all in bilateral symmetry.
B. body components are arranged around a central axis in radial symmetry, but are arranged with a distinct left and right in bilateral symmetry.
C. radial symmetry only occurs in round organisms like the sponges, while bilateral symmetry is common to all of the more complex animals.
D. animals with radial symmetry demonstrate cephalization, while those with bilateral symmetry do not.
E. radial symmetry is characterized by the animal having a coelom, while bilateral symmetry has no coelom in the animal body.


Answer: B. body components are arranged around a central axis in radial symmetry, but are arranged with a distinct left and right in bilateral symmetry.
