  • Question 1
    1 / -0
    Which one of the following species of earthworm is not recommended for vermicomposting?
    Solution
    All earthworms are not used for vermicompost. Earthworms are classified as humus formers and humus feeders. Among which humus formers are good for vermicompost and they include Eudrilus eugenics, Eisenia fetidae, Perionyx excavators. Pheretima posthuma is not recommended for vermicomposting as it is a humus feeder.
  • Question 2
    1 / -0
    The image formed in the eyes of cockroach is
    Solution
    The eye of the cockroach is the compound type and is composed of many units called ommatidium. There are individual images formed by these units as they are innervated with axon bundles which send the picture element to the brain. The final image which is observed by the eyes is the superposition of all the individual images from the ommatidia in the brain. 
    Thus, the correct answer is option B. 
  • Question 3
    1 / -0
    Which is not correct for earthworm?
    Solution
    The earthworm has a maximum crawling velocity of 25 cm/min. It can remain without oxygen for almost a day. The average life span of earthworms is species-dependent and have the potential to live 4-9 years under protected growing conditions. Setae are made of chitin, a nitrogenous polysaccharide, which is hardened and darkened by impregnation with insoluble proteins, known as scleroproteins and hence cannot be dissolved easily in potassium hydroxide. So, the correct answer is option D.
  • Question 4
    1 / -0
    In earthworm, gizzard is found in
    Solution
    The digestive system of earthworm consists of a mouth, a pharynx, an oesophagus, a crop, a gizzard and an intestine. In the 8th segment, the oesophagus expands and modifies into a large, distinct, muscular organ, called as the gizzard. So, the correct answer is option B.
  • Question 5
    1 / -0
    Stink gland is found in
    Solution
    The intersegmental membrane between $$5^{th}$$ and $$6^{th}$$ terga is depressed on either side of the stink gland. These glands produce a secretion with a characteristic odour.
    Therefore, the correct answer is option B.
  • Question 6
    1 / -0
    The type of connective tissue that is associated with the umbilical cord is
    Solution
    The intracellular mucoid connective tissue of the umbilical cord is called the Wharton's jelly. So, the tissue that is associated with umbilical cord is jelly-like in nature. It provides support for the veins and arteries of the umbilical chord. It is a clear jelly like substance which collapses when taken out from the mother's body.
    Thus, the correct answer is option B.
  • Question 7
    1 / -0
    Camel's hump is made up of
    Solution
    • Adipose tissue is a form of connective tissue consisting mainly of fat cells or adipose cells specialized to synthesize and contain large globules of fat, within a structural network of fibers. 
    • It is a myth that camel's hump contains water and hence, they can go for several days without water. This is wrong. 
    • The camel's hump is in fact composed of adipose cells or fat cells. Camels break down the fats, when needed and utilize them.

    Thus, the correct answer is option (D), 'Adipose tissue'.
  • Question 8
    1 / -0
    Note the following statements.
    a. It forms the lining of the cavities of alveoli of the lungs.
    b. It forms the lining of wet surfaces like buccal cavity and oesophagus.
    c. It occurs in the ducts of sweat glands.
    d. It forms the lining of salivary glands and sweat glands.
    e. It is a loose connective tissue.
    Which of the above are associated with simple epithelial tissue?
    Solution
    Simple epithelium is one cell thick. So, in this case, every cell is in direct contact with the underlying basement membrane. In general, it is found, where absorption and filtration occurs. Simple squamous, simple cuboidal, simple columnar and simple pseudostratified are four major classes of the simple epithelium. Simple squamous epithelium is found lining the areas where passive diffusion of gases occur, including the walls of the capillaries, the lining of the alveoli of the lungs and the lining of the pericardial, pleural and peritoneal cavities. The inner surfaces of salivary and sweat glands are also lined by simple epithelia.
    Thus, the correct answer is the option (A), 'a and d'.
  • Question 9
    1 / -0
    Ciliated epithelium in vertebrates is present in
    Solution
    A) Correct answer- B
    B)  Explanation for the correct answer 

    Option B:
    • The ciliated epithelium is the layer of simple epithelial cells but they possess fine hair-like outgrowths i.e., cilia on their free surfaces.
    • These cilia are capable of rapid, rhythmic, wavelike beatings in a certain direction.
    • This assists in removing dust particles and foreign bodies, which have entered air passages.
    • In frogs, it is found in the buccal cavity and oviduct.

    C) explanation of incorrect options
    Option A: Kidney and stomach have simple cuboidal and columnar cells respectively.
    option C: Urinary tubules are lined by cuboidal epithelium.
    option D: lymph vessels have simple squamous epithelium.
  • Question 10
    1 / -0
    5th cranial nerve of frog is called
    Solution
    • There are 10 pairs of cranial nerves in a frog. 
    • The fifth cranial nerve is the trigeminal nerve, which is a somatic sensory nerve.
    • Its origin is from the medulla and bears a Gasserian ganglion. 
    • It receives impulses from the skin of the snout. 
    • It has ophthalmic, maxillary and mandibular nerve which receives impulses from the skin of the upper jaw, supplies muscles of the upper jaw and supplies the muscles of the lower jaw respectively.
    So, the correct answer is option C.
