Questions and Answers
  • 1. 

    How many bones are there in the adult body?

    • A.

      206

    • B.

      300

    • C.

      150

    • D.

      100

    Correct Answer
    A. 206
    Explanation
    The adult human body has 206 bones. This is the correct answer because it is the widely accepted and documented number of bones in the human skeleton. The human skeleton is made up of the axial skeleton, which includes the skull, vertebral column, and rib cage, and the appendicular skeleton, which includes the bones of the limbs and the girdles that connect them to the axial skeleton. The 206 bones in the adult body provide structure, support, and protection for various organs and tissues, and they also allow for movement and mobility.

    Explanation
    The spinal cord is a long, cylindrical bundle of nerves that extends from the base of the brain to the lower back. It is responsible for transmitting signals between the brain and the rest of the body, allowing for communication and coordination of movement, as well as the transmission of sensory information. The spinal cord is not a muscle, bone, or artery, but rather a crucial component of the nervous system.

It is composed of several sublayers, including the stratum corneum and the basal layer. The dermis is the deeper layer and contains blood vessels, nerves, hair follicles, and sweat glands. These two layers work together to regulate body temperature, protect against pathogens, and provide sensation to touch and pressure.

    Explanation
    Arteries are the correct answer because they are the tubes that carry blood away from the heart. They have thick and elastic walls that help to maintain blood pressure and transport oxygenated blood to various parts of the body. Veins, on the other hand, carry blood back to the heart, nerves transmit signals throughout the body, and capillaries are tiny blood vessels that connect arteries and veins.

      Sulfur

    • D.

      Hydrogren dioxide

    Correct Answer
    A. Carbon dioxide
    Explanation
    When humans breathe in, they inhale oxygen from the air. During the process of cellular respiration, oxygen is utilized by the body's cells to produce energy. As a result of this process, carbon dioxide is produced as a waste gas and is then exhaled from the body through the lungs. Therefore, the waste gas that humans breathe out is carbon dioxide.

    Correct Answer
    C. Red and white
    Explanation
    Blood cells are typically red and white in color. Red blood cells contain a pigment called hemoglobin, which gives them a red color. These cells are responsible for carrying oxygen to different parts of the body. White blood cells, on the other hand, are colorless and play a crucial role in the immune system, fighting against infections and diseases. Therefore, the correct answer is red and white.

    Explanation
    The largest organ of the human body is the skin. It covers the entire body and serves as a protective barrier against external factors such as bacteria, UV radiation, and physical injuries. The skin also helps regulate body temperature, stores fat and water, and plays a crucial role in sensation and touch. Additionally, it is involved in the production of vitamin D and acts as a means of excretion through sweat.

    • D.

      Pink

    Correct Answer
    A. Black
    Explanation
    The correct answer is black because the color of the pupils in our eyes is determined by the amount of light that enters the eye. Pupils appear black because they are actually just openings that allow light to enter the eye and reach the retina. The black color is a result of the light being absorbed by the tissues inside the eye and not being reflected back out.
