Accepted Answer

Hello everyone here? We have a question that says blank body symmetry is two sponges, as blank body symmetry is to animals. So an animal or a sponge, if we look at the bottom of it is going to be a circle because they're long cylinders. So there's a central access point from which its body poets radiate out of. So it has radial body symmetry. Now, animals like a human. If we look at has bilateral symmetry, meaning if we draw a line down the middle there will be mere image is like having an arm on both sides. So our answer here is a radial and bilateral. Thank you for watching. Bye.
