    • True

    • False

    Correct Answer
    A. False
    Explanation
    Bottle-nose dolphins do not have the same whistle. Each dolphin has its own unique whistle that acts as its individual vocal signature. These whistles are used for communication and identification purposes among dolphins. This individuality in whistles helps dolphins recognize and differentiate themselves from others in their social groups. Therefore, the correct answer is false.

    Flukes are not the fins on the dolphin's tail. Flukes are actually the two lobes at the end of the dolphin's tail, which are used for propulsion and steering. The fins on a dolphin's tail are called flippers, and they are located nearer to the body. Therefore, the correct answer is false.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Dolphins can sleep, but they have a unique way of doing so. They rest one half of their brain at a time, while the other half remains awake to control breathing and maintain body functions.

They have blowholes on top of their heads, which they use to breathe and also to smell. Dolphins can detect odors in the water, helping them find prey, avoid predators, and identify other dolphins. Their sense of smell is crucial for their survival and plays a significant role in their daily activities.
