Answer:
A key feature of animal body plans is that they can show multiple types of symmetry.For example,,a dog would represent bilateral symmetry,while a jellyfish and other cnidarians would represent <u><em>radial symmetry</em></u>.
Explanation:
In biology, symmetry can be described as the balanced distribution of the body shape of an organism.
Radial symmetry can be described as a symmetry which depends on a central axis. The symmetry of cnidarians depends on a central axis hence they have radial symmetry.
Bilateral symmetry can be described as a symmetry in which the two halves of the symmetry are mirror images of one another. For example, humans, dogs etc.
