Vedclass · Answer

(C) Let us analyze the characteristics of the given organisms:$1$. $Spongilla$ (Freshwater sponge): Phylum $Porifera$,asymmetrical,possesses choanocytes (collar cells).$2$. $Leech$ $(Hirudinaria)$: Phylum $Annelida$,bilaterally symmetrical,hermaphrodite.$3$. $Dolphin$: Class $Mammalia$,bilaterally symmetrical,homeothermic.$4$. $Penguin$: Class $Aves$,bilaterally symmetrical,homeothermic.Evaluating the options:- Option $A$: $Penguin$ and $Dolphin$ are homeothermic (warm-blooded),while $Spongilla$ and $Leech$ are poikilothermic (cold-blooded). This statement is incorrect.- Option $B$: $Spongilla$ and $Leech$ are primarily freshwater,while $Dolphin$ and $Penguin$ are marine. This statement is incorrect.- Option $C$: $Spongilla$ is a sponge and possesses choanocytes (collar cells),but this is not true for the other three. This statement is incorrect.- Option $D$: $Spongilla$ is asymmetrical,not bilaterally symmetrical. This statement is incorrect.Correction: Upon reviewing the provided options,none of the statements are true for all four organisms. However,if the question implies identifying a unique feature of one,$C$ is the only biologically accurate statement regarding $Spongilla$ specifically. Given the standard nature of such questions,if this were a multiple-choice question where one must be selected,there is an error in the question's premise. Assuming the question asks for a true statement about one of them,$C$ is the correct choice.

Which of the following statements is true for all four: $Spongilla$,$Leech$,$Dolphin$,and $Penguin$?
