Although most animals are bilaterally symmetrical, a few exhibit radial symmetry. what is an advantage of radial symmetry?
it confuses predators.
it allows the animal to gather food from all sides.
it allows the animal to undergo rapid, purposeful movement in any direction.
it lets an animal use its dorsal surface to sense its environment.

It allows the animal to undergo rapid, purposeful movement in any direction.

Explanation:

The radial symmetry allows the animal to have a more controlled displacement, this advantage is evidenced in the response to predators which is faster than an animal with bilateral symmetry.

Also predators know its preys so they usually don't get confuse about their shape. No necessarily for having a radial symmetry the animal gets food from all sides ( the seastars have radial symmetry but the movement of their extremities do not allow them to get food from every place around). And sensing the environment is not necesarily an advantage because it don't let you know what is above you.

So an advantage of radial symmetry is the huge capacity of movement.

It allows the animal to undergo rapid, purposeful movement in any.

Explanation:

answer; ///i believe the correct answer is (

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good
