What part of prawn is used specifically for sensory purposes?

Explanation

Prawns are a type of crustacean that have several body parts serving different functions. The question is asking which specific part of the prawn is used for sensory purposes. The options listed are carapace, mandible, tracheae, proboscis, and antennae. To answer the question correctly, we need to know what each of these body parts does. The carapace is the hard, protective covering over the prawn's body. It does not have any sensory function. The mandibles are the prawn's mouthparts that help it to crush and grind its food. The tracheae are the tubes that allow the prawn to breathe, and they do not have any sensory function. The proboscis is a long, flexible tube-like structure that some animals use to suck up their food. However, prawns do not have a proboscis. That leaves us with the antennae, which are the correct answer. Prawns have two pairs of antennae, and they are used for touch, taste, and smell. The antennae are sensitive to chemicals in the water, which allows the prawn to locate food and avoid danger. In summary, the correct answer to the question is option E: antennae. The antennae are the part of the prawn that is used specifically for sensory purposes, including touch, taste, and smell.
