Nudibranchs, a type of predatory sea slug, can have various protuberances (i.e., extensions) on their dorsal surfaces. Rhinophores are paired structures, located close to the head, which bear many chemoreceptors. Dorsal plummules, usually located posteriorly, perform respiratory gas exchange. Cerata usually cover much of the dorsal surface and contain nematocysts at their tips.
-The antennae of insects have a function most similar to that of
A) rhinophores.
B) dorsal plummules.
C) cerata.
D) more than one of these.

Question

Quizplus · Accepted Answer

The function of the antennae of insects is similar to that of rhinophores in nudibranchs, as both structures bear chemoreceptors used in detecting and locating food sources. Dorsal plummules are involved in gas exchange, while cerata contain nematocysts for defense and feeding purposes.
