Body design and terms of direction

Question 1

____ - an animal body that can be divided into similar halves by a cut in any direction through the center.

Answer 1

Spherical or Universal

Question 2

-an animal form that can be divided into similar parts radiating out from the central axis.

Answer 2

Radial

Question 3

refers to the symmetry of an oval-bodied animal, - in which, because of some parts that are single or paired rather than radial, only planes passing through the oral-aboral axis produce mirrored halves.

Answer 3

Biradial
