Porifera
Correct Answer
D. PoriferaExplanation
A sponge belongs to the phylum Porifera. Porifera is a phylum of simple multicellular organisms that lack true tissues and organs. Sponges are filter feeders that live in aquatic environments, and they have a porous body structure with specialized cells called choanocytes that help them filter and circulate water. They are considered the simplest and most primitive animals, and they play important roles in marine ecosystems.Rate this question:

Mollusca, bivalves
- B.
Arthropoda, arachnids
- C.
Arthropoda, crustaceans
- D.
Mollusca, gastropods
Correct Answer
C. Arthropoda, crustaceansExplanation
Barnacles belong to the phylum Arthropoda and the order Crustacea. This is because barnacles have jointed appendages and a hard exoskeleton, which are characteristics of arthropods. Additionally, barnacles are crustaceans, a specific group within the phylum Arthropoda that includes animals such as crabs, lobsters, and shrimp. Therefore, the correct answer is Arthropoda, crustaceans.Rate this question:

Clam

- A.
Starfish
- B.
Shrimp
- C.
Sponge
- D.
Earthworm
Correct Answer
C. SpongeExplanation
A sessile animal is one that is permanently attached to a surface and does not move around. Among the given options, a sponge is the only animal that fits this description. Sponges are filter-feeding organisms that attach themselves to surfaces such as rocks or coral reefs. They do not have the ability to move from one place to another, making them sessile. In contrast, starfish, shrimp, and earthworm are all capable of movement and are not considered sessile animals.Rate this question:

If you found an animal that has an exoskeleton and jointed legs, which phylum would you put it in?
- A.
Arthropoda
- B.
Echinodermata
- C.
Platyhelminthes
- D.
Mollusca
Correct Answer
A. ArthropodaExplanation
Arthropoda is the correct answer because it is the only phylum that includes animals with both an exoskeleton and jointed legs. Echinodermata is incorrect because although it has an exoskeleton, it does not have jointed legs. Platyhelminthes and Mollusca are also incorrect because they do not have an exoskeleton or jointed legs.Rate this question:
