  • Question 1
    1 / -0
    Chromophil cells found in the pharyngeal mass function like
    Solution
    The pharynx of the earthworm is with a narrow and dorsoventrally compressed but laterally expanded pharyngeal cavity. It is due to presence of a pharyngeal mass on its dorsal side. This pharyngeal mass consists of chromophil cells which are saliva-secreting cells. These cells secrete salivary-secretion, containing mucus and proteolytic enzymes, that are poured into the salivary chamber.
    Therefore, the correct answer is option B.
  • Question 2
    1 / -0
    Fat deposits are found in:
    Solution
    Adipose tissue is a loose connective tissue composed mostly of adipocytes or fat cells. These help in the protection of vital organs and act as an insulating layer.
    So, the correct answer is option C.
  • Question 3
    1 / -0
    In which of the following animal, respiration occurs without any respiratory organ?
    Solution
    Respiratory organs are lacking in earthworm and gaseous exchange takes place through the skin, which is richly supplied with blood vessels and has to be kept moist by excretion of coelomic fluid through the dorsal pores. Carbon dioxide also diffuses from blood to the skin from where it is eliminated.
    Hence, option D is the correct answer.
  • Question 4
    1 / -0
    Areolar connective tissue joins:
    Solution
    answer:
    Correct Answer: C
    Explanation:
    • Areolar connective tissue is a type of connective tissue whose main function is to bind the various part together.
    • It is a loose connective tissue which binds skin epithelia with muscles or it also binds with nerves and blood vessels.
    • It mainly attaches the surface epithelial layer with the underlying layers.
    Hence, the areolar connective tissue joins skin with muscle.
  • Question 5
    1 / -0
    In which one of the following preparation are you likely to come across cell junctions most frequently?
    Solution
    Epithelia are formed of cells that line the cavities in the body and also cover flat surfaces. Epithelial cells are bound together in sheets of tissue called epithelia. These sheets are held together by several types of interactions including tight junctions, adherens, desmosomes and gap junctions.
    Thus, the correct answer is the option (D), 'Ciliated epithelium'.

  • Question 6
    1 / -0

    Which of the following tissues lines the blood vessels?

    Solution

    Blood vessels are lined by single-layered simple squamous epithelium tissue called the endothelium. The endothelium is the thin layer of cells that line the interior surface of blood vessels. It helps in the exchange of materials like gases and nutrients between the blood and the body tissues.

    Thus, the correct option is B.

  • Question 7
    1 / -0
    The difference between integumentary and pharyngeal nephridia relates to
    Solution
    Integumentary nephridia lie attached to the inner side of the body wall in all segments except the first two. The pharyngeal nephridia are located only in the 4th, 5th and 6th segments. These two nephridia extract only waste matter from the capillaries with which they are richly supplied. It is only the integumentary nephridia which open directly to the exterior and so they are called as exonephric nephridia.
    Therefore, the correct answer is option C.
  • Question 8
    1 / -0
    Match the type of connective tissues listed under column I with the functions listed under column II. Choose the choice, which gives the correct combination of the alphabets of the two columns.
    Connective tissues
    Functions
    A. Ligament
    p. Stores fat
    B. Tendons
    q. Connects bone to bone
    C. Areolar tissue
    r. Connects muscle to bone
    D. Adipose tissue
    s. Forms blood cells

    t. Filling tissue
    Solution
    • The ligament is the fibrous tissue that connects bones to other bones. 
    • Tendon is a tough band of fibrous connective tissue that connects muscle to bone. 
    • Areolar tissue is the connective tissue with fibres arranged in a mesh or net and acts as a filling tissue. 
    • Adipose tissue or body fat or simply fat is a loose connective tissue composed of adipocytes or fat cells, which stores fats. 
    So, the correct answer is option A.
  • Question 9
    1 / -0
    Match the types of the animal tissues with the parts / organs in which they occur. Choose the answer, which gives the correct combination of the alphabets of the two columns.
    Tissue
    Part / organ
    A. Squamous epithelium
    p. Below the skin
    B. Hyaline cartilage
    q. Bowman's capsule
    C. Adipose tissue
    r. Walls of stomach
    D. Smooth muscles
    s. Trachea

    t. Duct of glands

    Solution
    Squamous epithelium cells are composed of a large flat whose edges it closely together like the tiles in a floor and it forms the wall of Bowman's capsule. Hyaline cartilage is a translucent, slightly elastic matrix with less fibre and forms a ring of the trachea. Adipose tissue is a fat-storing tissue which is present below the skin. Smooth muscles are involuntary muscles. It composes of muscles of internal organs and the digestive system. Thus, the correct answer is D.
  • Question 10
    1 / -0
    Anal styles are found in
    Solution
    In male cockroaches, the 9th segment bears a pair of short, a thread like anal styles, which are absent in females. The anal style sense something is coming from the cockroaches back and allows it to run in the opposite direction. So, the correct answer is option C.
