Question

One of the following exhibits moulting:

• A. Tapeworm
• B. Palaemon
• C. Hydra
• D. Sponges

Hint:

Remember that moulting is typical in arthropods, allowing growth by shedding the exoskeleton.

Answer 1

The Correct Option is B

Step 1: Moulting is the process in which an organism sheds its exoskeleton or outer layers to grow. It is most commonly observed in arthropods (e.g., insects, crustaceans) and some other invertebrates. 
Step 2: Palaemon, commonly known as the prawn, is a crustacean and exhibits moulting as part of its growth process. Prawns shed their exoskeleton periodically to allow for growth. 
Step 3: Tapeworms (Option 1) are parasitic flatworms and do not exhibit moulting. They grow by absorbing nutrients from their host. 
Step 4: Hydra (Option 3) is a small, freshwater cnidarian that does not undergo moulting. It reproduces mainly through budding. 
Step 5: Sponges (Option 4) are simple invertebrates that do not undergo moulting. They grow by cell division and regeneration. 
Conclusion: Only Palaemon (the prawn) exhibits moulting among the given options.
