Question

Use the following information to answer the question. Nudibranchs, a type of predatory sea slug, can have various protuberances (that is, extensions) on their dorsal surfaces. Rhinophores are paired structures, located close to the head, which bear many chemoreceptors. Dorsal plumules, usually located posteriorly, perform respiratory gas exchange. Cerata usually cover much of the dorsal surface and contain nematocysts at their tips. The stingers of honeybees have a function most similar to that of ________. a rhinophores b dorsal plumules c cerata d chemoreceptors

Answer 1

The preferable option will be - A.

A. Rhinophores.

Explanation:

The stingers or antenna of honeybees have a function most similar to that of rhinophores. Both of them act as a chemoreceptor or chemosensory organs for those animals.

• The Nudibranchs, a type of sea slug have Rhinophores. The rhinophores are taste-scent receptors or also known as chemosensory organs that have club-shaped or rod-shaped or ear-like structures.
• They are prominently visible at the dorsal surface of the head of the sea slugs. They detect the chemicals which are dissolved in the seawater thus they detect the scent.
• In the sea, they are also able to detect food and pheromones.
