Questions and Answers
  • 1. 

    The largest living sea predator

    • A.

      Viper fish

    • B.

      Giant tube worm

    • C.

      Sperm whale

    • D.

      Angler fish

    Correct Answer
    C. Sperm whale
    Explanation
    The sperm whale is the largest living sea predator because it has a massive size and powerful hunting capabilities. It can grow up to 60 feet long and weigh over 50 tons, making it the largest toothed predator on Earth. Sperm whales have a diet primarily consisting of squid, which they catch by diving to great depths and using their strong jaws and teeth to capture their prey. Their large size and hunting abilities make them the top predator in the ocean.

    A tissue which surrounds the developing embryo of a seed

    • A.

      Outer seed coat

    • B.

      Embryo

    • C.

      Endosperm

    • D.

      None of the above

    Correct Answer
    C. Endosperm
    Explanation
    The endosperm is a tissue that surrounds the developing embryo of a seed. It provides nourishment and support to the growing embryo during germination and early stages of growth. It contains nutrients such as starch, proteins, and oils, which are essential for the embryo's development. The outer seed coat, on the other hand, serves as a protective layer for the seed. Therefore, the correct answer is endosperm.

    Inflammation of stomach lining

    • A.

      Gastritis

    • B.

      Leptospirosis

    • C.

      Cholera

    • D.

      A(H1N1)

    Correct Answer
    A. Gastritis
    Explanation
    Gastritis refers to the inflammation of the stomach lining. This condition can be caused by various factors such as excessive alcohol consumption, prolonged use of nonsteroidal anti-inflammatory drugs (NSAIDs), bacterial infection (such as Helicobacter pylori), or autoimmune diseases. Symptoms of gastritis may include abdominal pain, bloating, nausea, vomiting, and loss of appetite. Treatment typically involves medication to reduce stomach acid, antibiotics if there is an underlying infection, and lifestyle changes such as avoiding triggers like spicy foods and alcohol.

  • 4. 

    Which part of a plant holds it upright and moves it towards light?

    • A.

      Roots

    • B.

      Stem

    • C.

      Flower

    • D.

      Leaves

    Correct Answer
    B. Stem
    Explanation
    The stem of a plant holds it upright and moves it towards light. The stem provides structural support to the plant, allowing it to stand tall and not collapse under its own weight. Additionally, the stem contains specialized cells called phototropins, which detect the direction of light and cause the stem to grow towards it. This movement is known as phototropism and helps the plant maximize its exposure to sunlight for photosynthesis.

    The method where plants use seeds, stems, leaves to produce other plants.

    • A.

      Plant duplication

    • B.

      Plant replication

    • C.

      Plant propagation

    • D.

      Plant reproduction

    Correct Answer
    D. Plant reproduction
    Explanation
    The given correct answer is "plant reproduction". This term refers to the process in which plants use seeds, stems, or leaves to produce new plants. It involves the transfer of genetic material from one generation to the next, ensuring the survival and continuation of the plant species. Plant reproduction is essential for the growth and expansion of plant populations.

    Process where plants make their own food

    • A.

      Reproduction

    • B.

      Synthesis

    • C.

      Propagation

    • D.

      None of the above

    Correct Answer
    D. None of the above
    Explanation
    The given question is asking for a process where plants make their own food. The options provided are reproduction, synthesis, propagation, and none of the above. None of the above is the correct answer because the process where plants make their own food is called photosynthesis. This is the process by which plants use sunlight, water, and carbon dioxide to produce glucose and oxygen. Reproduction, synthesis, and propagation are not directly related to the process of plants making their own food.

    State of matter that has a definite size and shape

    • A.

      Solid

    • B.

      Liquid

    • C.

      Gas

    • D.

      Plasma

    Correct Answer
    A. Solid
    Explanation
    A solid is a state of matter that has a definite size and shape. Unlike liquids and gases, solids have particles that are tightly packed together and maintain a fixed arrangement. This allows them to maintain a specific shape and volume. In solids, the particles vibrate in place but do not move around freely like in liquids or gases. Examples of solids include ice, wood, and metal.

    Last but not the least, Green pigment in plants

    • A.

      Chloroplast

    • B.

      Chlorophyll

    • C.

      Vitamins

    • D.

      Minerals

    Correct Answer
    B. Chlorophyll
    Explanation
    Chlorophyll is the green pigment found in chloroplasts, which are the organelles responsible for photosynthesis in plants. Chlorophyll absorbs light energy from the sun and converts it into chemical energy, which is used to produce glucose and oxygen. This process is essential for plants to carry out photosynthesis and produce food. Therefore, the correct answer is chlorophyll.
