Vedclass · Answer

(C) $1$. Thorns of Bougainvillea and tendrils of Cucurbita are homologous organs because they share a common anatomical origin (axillary buds) but perform different functions. Thus,option $A$ is incorrect.$2$. In the human eye,the blind spot is a physiological region where the optic nerve exits,while the eyelid is a protective structure. Neither is a vestigial organ. Thus,option $B$ is incorrect.$3$. Nephridia are the primary excretory organs in earthworms $(Pheretima)$,and Malpighian tubules are the primary excretory organs in cockroaches $(Periplaneta)$. This is a correct match. Thus,option $C$ is correct.$4$.
