Questions and Answers
  • 1. 

    Which of these is a mammal?

    • A.

      Peacock 

    • B.

      Ostrich 

    • C.

      Bat

    • D.

      Flamingo 

    Correct Answer
    C. Bat
    Explanation
    A bat is a mammal because it possesses all the characteristics that define mammals. It has fur or hair, gives birth to live young, and nurses its offspring with milk. Bats also have a warm-blooded metabolism and possess specialized adaptations for flight, such as wings. Therefore, out of the given options, the bat is the only one that fits the criteria of being a mammal.

    What is the act of responding to stimulus? 

    • A.

      Growth

    • B.

      Responsiveness 

    • C.

      Irritability 

    • D.

      Nutrition 

    Correct Answer
    C. Irritability 
    Explanation
    Irritability is the correct answer because it refers to the ability of an organism or a cell to respond to a stimulus. This response can be in the form of movement, secretion, or other physiological changes. Irritability allows organisms to adapt and survive in their environment by responding to changes and stimuli.

    What is the framework of the body? 

    • A.

      Skeleton 

    • B.

      Bone 

    • C.

      Muscles 

    • D.

      Tendon 

    Correct Answer
    A. Skeleton 
    Explanation
    The framework of the body refers to the structure that provides support and shape. The skeleton is the correct answer because it is the framework made up of bones that support and protect the body's organs and tissues. The skeleton also allows for movement and provides attachment points for muscles and tendons.

    Which of these is used in measuring the mass of an object?

    • A.

      Beam balance 

    • B.

      Spring balance 

    • C.

      Barometer 

    • D.

      Anemometer 

    Correct Answer
    A. Beam balance 
    Explanation
    A beam balance is used in measuring the mass of an object. It consists of a horizontal beam that is balanced on a fulcrum, with pans suspended from each end. The object whose mass is to be measured is placed on one pan, and standard weights are added to the other pan until the beam is balanced. This allows for an accurate determination of the object's mass.

  • 5. 

    Which of these is not an effect of friction?

    • A.

      Heat while rubbing hands 

    • B.

      Walking 

    • C.

      Wear and tear 

    • D.

      Vasolidation

    Correct Answer
    D. Vasolidation
    Explanation
    Vasolidation is not an effect of friction. Friction is the force that opposes the motion of objects in contact with each other. When we rub our hands together, friction generates heat. Walking involves friction between our feet and the ground, which allows us to move forward. Wear and tear is also a result of friction, as it causes surfaces to gradually degrade over time. However, vasolidation, which refers to the dilation of blood vessels, is not directly related to friction.

    What are the young ones of toad called? 

    • A.

      Calf

    • B.

      Frogs 

    • C.

      Tadpoles

    • D.

      Kids

    Correct Answer
    C. Tadpoles
    Explanation
    Tadpoles are the young ones of toads. They are aquatic larvae that hatch from eggs laid by adult toads. Tadpoles have gills and a tail, and they undergo a process called metamorphosis to develop into adult toads. During metamorphosis, they gradually lose their tails, grow legs, and develop lungs to adapt to a terrestrial lifestyle. Therefore, the correct answer is tadpoles.

  • 7. 

    Which of these groups does Snail belongs?

    • A.

      Amphibians 

    • B.

      Arthropods

    • C.

      Molluscs

    • D.

      Arachnids

    Correct Answer
    C. Molluscs
    Explanation
    Snails belong to the group of Molluscs. Molluscs are a diverse group of invertebrates that typically have a soft body, a muscular foot, and a hard shell. Snails have a soft body protected by a spiral-shaped shell, which is characteristic of molluscs. They are not amphibians, arthropods, or arachnids, as these groups have different characteristics and classifications.

  • 8. 

    Which of these is a source of lactic acid?

    • A.

      Citrus 

    • B.

      Grape 

    • C.

      Sour milk 

    • D.

      Vinegar 

    Correct Answer
    C. Sour milk 
    Explanation
    Sour milk is a source of lactic acid because it contains bacteria called Lactobacillus which ferments lactose, the sugar in milk, into lactic acid. This fermentation process gives sour milk its characteristic tangy taste. Lactic acid is commonly used in the food industry as a preservative, flavoring agent, and pH regulator. It is also produced in our muscles during intense exercise, leading to muscle fatigue and soreness.

  • 9. 

    Which of these is not a bone? 

    • A.

      Scapula 

    • B.

      Femur 

    • C.

      Tibia 

    • D.

      Tendon 

    Correct Answer
    D. Tendon 
    Explanation
    A tendon is not a bone because it is a tough and flexible band of fibrous tissue that connects muscle to bone. It is responsible for transmitting the force generated by the muscle to the bone, allowing movement. In contrast, the scapula, femur, and tibia are all bones. The scapula is the shoulder blade, the femur is the thigh bone, and the tibia is the shin bone.

    What causes motion?

    • A.

      Force

    • B.

      Density 

    • C.

      Momentum 

    • D.

      Time 

    Correct Answer
    A. Force
    Explanation
    Force is the correct answer because it is the fundamental cause of motion according to Newton's laws of motion. An object will remain at rest or continue moving in a straight line at a constant speed unless acted upon by an external force. Force can be defined as a push or pull that can change the state of motion of an object. It can accelerate an object, decelerate it, or change its direction. Therefore, force is the underlying factor that causes any kind of motion to occur.
