Starfish, also known as sea stars, belong to this group and exhibit all the typical characteristics of echinoderms.

An earthworm belongs to which phylum?
- A.
  
  Arthropoda
- B.
  
  Porifera
- C.
  
  Annelida
- D.
  
  Cnideria
Correct Answer
C. Annelida

Explanation
An earthworm belongs to the phylum Annelida because this phylum includes segmented worms, such as earthworms, leeches, and marine worms. Annelids are characterized by their elongated and segmented bodies, with each segment containing a set of organs. They have a closed circulatory system and a well-developed nervous system. Earthworms, specifically, are known for their important role in soil health and nutrient cycling. They are hermaphroditic and play a crucial role in breaking down organic matter in the soil, making them essential for the ecosystem.

  Amphibia
- C.
  
  Mollusca
- D.
  
  Arthropoda
Correct Answer
D. Arthropoda

Explanation
The correct answer is Arthropoda. Arthropoda is a phylum that includes animals with jointed appendages, segmented bodies, and an exoskeleton. This animal is likely to belong to this phylum because it exhibits these characteristics. Platyhelminthes is the phylum of flatworms, Amphibia is the phylum of amphibians, and Mollusca is the phylum of mollusks, none of which match the characteristics described.

Which of these choices do an octopus and a clam have in common?
- A.
  
  They are both filter feeders.
- B.
  
  They are both molluscs.
- C.
  
  They both have an exoskeleton.
- D.
  
  They both have chromatophores.
Correct Answer
B. They are both molluscs.

Explanation
Octopuses and clams are both molluscs. Molluscs are a large phylum of invertebrate animals that include creatures such as snails, clams, octopuses, and squids. They share certain characteristics such as a soft body, a muscular foot for movement, and a mantle that secretes a shell in some species. While both octopuses and clams are molluscs, they differ in many other aspects. Octopuses are cephalopods, known for their intelligence and ability to change color, while clams are bivalves, known for their two-part hinged shells.

5.

Some members of this phylum have radial symmetry.
- A.
  
  Nematoda
- B.
  
  Porifera
- C.
  
  Cnideria
- D.
  
  Vertebrata
Correct Answer
C. Cnideria

Explanation
Members of the phylum Cnideria, such as jellyfish and sea anemones, have radial symmetry. This means that their body parts are arranged around a central axis, like the spokes of a wheel. This allows them to interact with their environment from all directions equally. Nematoda, Porifera, and Vertebrata do not have radial symmetry, making Cnideria the correct answer.
