  • 2. 

    Most of the fish can live on land.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Fish are aquatic animals and have adaptations that allow them to live and thrive in water. They have gills to extract oxygen from water and fins to help them swim. While some species of fish have the ability to survive for short periods out of water, they cannot live on land permanently. Their bodies are not designed to support their weight outside of water, and they require water to regulate their body temperature and maintain proper bodily functions. Therefore, the statement that most fish can live on land is false.

    Explanation
    Freshwater refers to water that contains a low concentration of salt or other dissolved substances. It is typically found in lakes, rivers, and underground sources such as aquifers.
