match the animals with their characteristics. exhibits the phenomenon of molting has a mantle and an open circulatory system have a coelom and a closed circulatory system has an endoskeleton made of calcium - rich plates

Answer

Brief Explanations:

  1. Earthworm: Have a coelom and a closed - circulatory system. Earthworms are annelids with a body cavity (coelom) and a closed - type circulatory system that keeps blood within vessels.
  2. Mollusk (e.g., the one in the shell): Has a mantle and an open circulatory system. Mollusks have a mantle that secretes the shell and an open circulatory system where blood is not always in vessels.
  3. Starfish: Has an endoskeleton made of calcium - rich plates. Starfish are echinoderms with an internal skeleton composed of calcium - carbonate plates.
  4. Spider: Exhibits the phenomenon of molting. Spiders are arthropods and shed their exoskeleton (molt) as they grow.

Answer:

Earthworm - have a coelom and a closed circulatory system Mollusk - has a mantle and an open circulatory system Starfish - has an endoskeleton made of calcium - rich plates Spider - exhibits the phenomenon of molting
