Question

Anne is observing an animal specimen. It has body parts that seem to extend from a central point, just like spokes in a bicycle wheel. Which animal is it most likely to be?

sponge


flatworm


crayfish

Answer 1

The answer is sponges.

Step-by-step explanation:

Animals with the radial symmetry of the body have body parts that seem to extend from a central point, just like spokes in a bicycle wheel.

Through the process of elimination:

Sponges have radial symmetry.

Flatworms have bilateral symmetry.

Crayfish have bilateral symmetry.

Therefore, among all choices, only sponges have body parts that seem to extend from a central point, just like spokes in a bicycle wheel

Answer 2

The answer is sponges.

Animals with the radial symmetry of the body have body parts that seem to extend from a central point, just like spokes in a bicycle wheel.

Through the process of elimination:
