Detailed explanation-1: -Sharks. Sharks can’t regenerate organs or other body parts but they can definitely regenerate their dental structures, as sharks can regrow teeth throughout their lifetimes.

Detailed explanation-2: -Sparrow does not have any regeneration ability.

Detailed explanation-3: -Plants and some sea creatures, such as jellyfish, can replace missing parts by extensively remodeling their remaining tissues. Some animals such as lobsters, catfish, and lizards replace missing parts by first growing a specialized bud of cells, called a blastema.

Detailed explanation-4: -In some organisms, regeneration is a form of asexual reproduction. In this method, the cut parts of the body of an organism give rise to new individuals. An example of an organism that reproduces through this method is Hydra.

Detailed explanation-5: -Regeneration is not possible in all types of animals because it is only possible in animals with specialised cells which cell proliferate and make large numbers of cells.
