    Skin is exposed to large amounts of UV rays...

    • Melanin is increased in skin for protection (tanning)

    • Sweating

    • Shivering

    • Hair on skin stands on end

    Correct Answer
    A. Melanin is increased in skin for protection (tanning)
    Explanation
    When the skin is exposed to large amounts of UV rays, the body increases the production of melanin. Melanin is a pigment that gives color to the skin, hair, and eyes. The increase in melanin is a protective response to the UV rays, as it helps to absorb and disperse the harmful radiation. This increase in melanin is commonly known as tanning, and it acts as a natural defense mechanism to protect the skin from further damage caused by the UV rays.

    • The snow hare changes colors to help with camoflauge

    • The porcupine has spikes

    • The posion arrow frog has bright colors

    • A dog sheds its coat

    Correct Answer
    A. The snow hare changes colors to help with camoflauge
    Explanation
    The snow hare changes colors to help with camouflage. This is a common adaptation in many animals that live in snowy environments. By changing its fur color to white, the snow hare can blend in with its surroundings and remain hidden from predators. This camouflage helps the snow hare to survive and increases its chances of finding food and avoiding becoming prey.

    The flower needs sunlight for photosynthesis...

    • The flower turns away from the sun

    • The flower follows the sun across the sky

    • The flower wilts

    • The flower changes color

    Correct Answer
    A. The flower follows the sun across the sky
    Explanation
    Plants undergo a process called phototropism, where they orient themselves towards a light source to maximize their exposure to sunlight. This is because sunlight is crucial for photosynthesis, the process by which plants convert light energy into chemical energy to fuel their growth. By following the sun across the sky, the flower ensures that it receives an optimal amount of sunlight throughout the day, allowing it to produce enough energy for its metabolic processes and maintain its overall health and vitality.

    Sunlight shines brighter...

    • Pupils of your eyes get larger

    • Pupils of your eyes get smaller

    • Eyes change color

    • Tears are produced

    Correct Answer
    A. Pupils of your eyes get smaller
    Explanation
    When sunlight shines brighter, the pupils of your eyes get smaller. This is because the iris, which controls the size of the pupil, contracts in response to increased light intensity. The contraction of the pupil helps to regulate the amount of light entering the eye, preventing excessive brightness from damaging the sensitive structures within the eye.
