Polymorphism is shown byA) PhysaliaB) TermiteC) TrypanosomaD) All of the above

D) All of the above

Polymorphism refers to the occurrence of different forms or morphs within the same species. All three options listed (Physalia, Termite, and Trypanosoma) represent examples of species that exhibit polymorphism:

A) Physalia: Physalia is a genus of marine organisms commonly known as Portuguese man o' war. It consists of specialized polyps responsible for functions like feeding, reproduction, and defense, which exhibit different forms and functions.

B) Termite: Termites are social insects that exhibit polymorphism within their colonies. Castes within a termite colony include workers, soldiers, and reproductives (kings and queens), each with distinct roles and appearances.

C) Trypanosoma: Trypanosoma is a genus of parasitic protozoa that includes species causing diseases like sleeping sickness in humans. These organisms can exhibit polymorphism in their life cycle, with different morphological forms adapting to various stages of their life cycle and different hosts.

So, the correct answer is D) All of the above.
