Answer:

A. share one common ancestor that isn't also shared by organisms in other groups.

Explanation:

A monophyletic group includes all the descendants of an ancestral species. On the other hand, a paraphyletic group includes some descendants of a common ancestor. Protists are not monophyletic as they share a common ancestor with other groups. Hence, protists are said to be paraphyletic. Mammals are monophyletic as all the mammals share a common ancestor which is not shared by organisms of any other groups.

Which characteristic is shared by cnidarians and flatworms? A) dorsoventrally flattened bodies
KatRina [158]

The correct option is (C) A digestive system with a single opening.

Which characteristic is shared by both cnidarians and Flatworms?

  • The class Soft-bodied stinging creatures like corals, sea anemones, and jellyfish are categorized as cnidaria. Numerous aquatic settings contain cnidarians. Sea anemones can be found all around the world, from the equator to the freezing northern regions and from small tide pools to the deep ocean floor.
  • Simple flatworm-like creatures belong to the phylum Platyhelminthes. Flatworms are parasites that live in or on other animals and are found on land, in fresh water, and in the ocean (e.g., tapeworms). Flatworm parasites can harm or even kill the host organism when they dwell on or inside of other species, including humans.
  • Although flatworms, like cnidarians, have a digestive system with only one opening into the digestive cavity, the cavity in independently living marine flatworms branches into every section of the body.
