Akey 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.

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 radial symmetry.

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.

it enhances antibody production by t cells of the adaptive immune system.

hope i'm right
