    Green plants make their food through - ProProfs

    Green plants make their food through

    • Cooking

    • Photosynthesis

    • System

    • Flow

    Correct Answer
    A. Photosynthesis
    Explanation
    Green plants make their food through photosynthesis. Photosynthesis is the process by which plants convert sunlight, carbon dioxide, and water into glucose and oxygen. This process occurs in the chloroplasts of plant cells, specifically in the chlorophyll pigment. Through photosynthesis, plants are able to produce their own food and release oxygen as a byproduct, which is essential for the survival of all living organisms.

    An example of optical phenomenon is - ProProfs

    An example of optical phenomenon is

    • Rainbow

    • Light

    • Ray

    • Sun

    Correct Answer
    A. Rainbow
    Explanation
    An example of an optical phenomenon is a rainbow. When sunlight passes through raindrops in the atmosphere, it undergoes refraction, dispersion, and reflection, resulting in the formation of a colorful arc in the sky. This phenomenon occurs due to the bending of light and the separation of its colors, creating a beautiful display of red, orange, yellow, green, blue, indigo, and violet.

    Photobiology studies the interactions of light with - ProProfs

    Photobiology studies the interactions of light with

    • Sand

    • Air

    • Water

    • Living organisms

    Correct Answer
    A. Living organisms
    Explanation
    Photobiology is a scientific field that focuses on studying the effects of light on living organisms. It investigates how light interacts with biological systems, including plants, animals, and microorganisms. This field explores various aspects such as photosynthesis, photomorphogenesis, circadian rhythms, and phototropism. By understanding these interactions, photobiologists can gain insights into the processes and mechanisms by which organisms respond and adapt to light.

    The organ responsible for the sense of sight is the - ProProfs

    The organ responsible for the sense of sight is the

    • Hair

    • Nail

    • Eye

    • Skin

    Correct Answer
    A. Eye
    Explanation
    The organ responsible for the sense of sight is the eye. The eye contains various structures such as the cornea, iris, lens, and retina, which work together to capture and focus light onto the retina. The retina then converts the light into electrical signals that are sent to the brain via the optic nerve, allowing us to perceive and interpret visual information.

    The main source of light on earth is - ProProfs

    The main source of light on earth is

    • Ray

    • Beam

    • Sun

    • Light

    Correct Answer
    A. Sun
    Explanation
    The sun is the main source of light on earth. It emits electromagnetic radiation, including visible light, which illuminates our planet. This light is essential for various biological processes, such as photosynthesis in plants and the regulation of circadian rhythms in animals. Additionally, sunlight provides warmth and energy, making it crucial for sustaining life on earth.

    Visible light is absorbed in tiny packets called - ProProfs

    Visible light is absorbed in tiny packets called

    • Shine

    • Beam

    • Photons

    • Ray

    Correct Answer
    A. Photons
    Explanation
    Visible light is absorbed in tiny packets called photons. Photons are fundamental particles of light that carry energy. When light interacts with matter, it is absorbed by the atoms or molecules, causing the electrons to gain energy and move to higher energy levels. This absorption of photons is responsible for the colors we perceive in the visible spectrum. Each photon has a specific amount of energy corresponding to its wavelength, and the absorption of photons determines the intensity and color of light that we see.

    A primary property of visible light is - ProProfs

    A primary property of visible light is

    • Intensity

    • Light

    • Visible

    • Ray

    Correct Answer
    A. Intensity
    Explanation
    Visible light is characterized by its intensity, which refers to the amount of energy carried by the light waves. Intensity determines the brightness or dimness of light, with higher intensity corresponding to brighter light and lower intensity corresponding to dimmer light. Therefore, intensity is a primary property of visible light as it directly affects how we perceive the brightness of objects and the overall illumination of our surroundings.

    The study of light is - ProProfs

    The study of light is

    • Lightning

    • Optics

    • Lightology

    • Network

    Correct Answer
    A. Optics
    Explanation
    Optics is the correct answer because it is the branch of physics that deals with the study of light and its behavior. It involves the study of how light interacts with matter, how it is produced and detected, and how it can be manipulated. This field encompasses various phenomena such as reflection, refraction, diffraction, and interference. By studying optics, scientists can understand the properties of light and develop technologies such as lenses, microscopes, telescopes, and lasers.

    The energy required to ionize an oxygen atom is - ProProfs

    The energy required to ionize an oxygen atom is

    • 10 eV

    • 105eV

    • 96eV

    • 2eV

    Correct Answer
    A. 10 eV
    Explanation
    The energy required to ionize an oxygen atom is 10 eV. Ionization refers to the process of removing an electron from an atom, turning it into an ion. The energy required for this process depends on the specific atom. In the case of oxygen, it takes 10 eV of energy to remove an electron and ionize the atom.
