Step-by-step explanation:
A double curve body refers to a body structure that exhibits two main curved regions. In biology, this term is commonly used to describe the shape of certain organisms, such as snakes and dolphins. These animals have a curved body shape that allows for efficient movement through their environments. For example, the curvy body of a snake helps it to move smoothly on various surfaces and navigate through tight spaces. Similarly, the double curves of a dolphin's body enable it to swim quickly and maneuver through water.
