alleryAnimals with left and right halves split by the sagittal plane show which symmetry?
ARadial
BBilateral
CSpherical
DAsymmetrical
Answer & Solution
Correct answer: B. Bilateral
1. The sagittal plane divides the body vertically into left and right halves.
2. Having one of each sense organ and limb pair on either side is bilateral symmetry.
3. Radial symmetry repeats parts around a central axis, and spherical or no symmetry does not fit.
