HELP!!! Ill give 30 points!!! Also what's the body symmetry of a sponge, cindaria, worms, and mollusk

a. Sponge

b. worm

c. mollusk

d. Cnidaria

The body symmetry of each organism you mentioned is as follows:

Sponge: Asymmetrical

Sponges have no definite body symmetry. Their body structure lacks any organized pattern or axis of symmetry.

Cnidaria (e.g., jellyfish, corals, sea anemones): Radial Symmetry

Cnidarians exhibit radial symmetry, which means their body parts are arranged around a central axis. They have multiple planes of symmetry, allowing them to be divided into equal halves through their central point.

Worms (e.g., earthworms): Bilateral Symmetry

Most worms, including earthworms, exhibit bilateral symmetry. This means their bodies can be divided into two equal halves along a single plane, resulting in a left and right side that are mirror images of each other.

Mollusks (e.g., snails, clams, octopuses): Bilateral Symmetry

Mollusks also have bilateral symmetry. Their bodies can be divided into two equal halves along a single plane, resulting in a left and right side that are mirror images of each other.

It's worth noting that while sponges and cnidarians have simple body plans and display asymmetry or radial symmetry, worms and mollusks have more complex body structures, and their bilateral symmetry is an adaptation that allows for greater mobility and more efficient movement in their environments.

I hope this helped!
