My go to quick-keto method is a coconut oil and cream fast. Basically just coffee, cream, and coconut oil for a day, top the day off with a bout of heavy weights before bed, tons of water, and I'm in ketosis in a day or 2.
Some well known gastropods, which are mollusks, are snails and slugs, and they exhibit what is known as BILATERAL SYMMETRY. The only other kind of symmetry that exists in the animal kingdom, with the exception of colonial species such as the sponge, is RADIAL SYMMETRY.
Asteroids have arms that are connected to each other. Also, it is harder to tell with asteroids where the central disk ends and the arms begin. A sea star is radially symmetrical. Radial symmetry means that the body is a hub, like a bicycle wheel, and tentacles are spokes coming out of it (think of a starfish).steroids have arms that are connected to each other.
