A pair of jointed appendages on the head used to sense the environment are called?

Explanation:
Antennae are the pair of jointed appendages on the head that serve as the main sensory organs for the environment, handling touch and chemical cues like smells. This is why they’re the best answer: mandibles are jaw-like mouthparts used for biting and chewing, maxillae help manipulate food, and palps are sensory structures associated with mouthparts but not the primary environmental sensors on the head. Antennae, by contrast, house receptors that let the organism detect odors, vibrations, humidity, and temperature, helping it explore and respond to its surroundings.
