Which group of organisms has the following features?1. Three pairs of jointed legs2. Three-part segmented body3. One pair of antennae

Explanation

In insects, the head bears a pair of antennae, which serve as important sensory organs for detecting smell, touch, and vibrations, and also carries compound eyes, each made up of many small visual units that provide a wide field of view. The insect body is divided into three distinct regions: head, thorax, and abdomen. The thorax, which is the locomotory center, consists of three segments prothorax, mesothorax, and metathorax. Each of these segments carries one pair of jointed legs, giving insects a total of three pairs of legs. Additionally, many insects bear one or two pairs of wings on the middle and last thoracic segments, making them the only invertebrates capable of active flight. The abdomen contains major internal organs, including those for digestion, excretion, and reproduction, completing the characteristic body plan of insects.
