  • Question 1/10
    4 / -1

    The outer layer in the cranium that prevents brain from mechanical shocks is known as __________.

    Solutions

    Dura mater is a thick membrane made of dense irregular connective tissue that surrounds the brain and spinal cord. It is the outermost of the three layers of membrane called the meninges that protect the central nervous system. The other two meningeal layers are the arachnoid mater and the pia mater.

    Hence, the correct option is (B).

     

  • Question 2/10
    4 / -1

    Which of the following is an antihistamine?

    Solutions

    Antihistamine is a drug that inhibits the physiological effects of histamine, used especially in the treatment of allergies.

    Brompheniramine is an antihistamine.

    Equanil is a tranquilizer.

    Ranitidine and Cimetidine are antacids.

    Hence, the correct option is (A).

     

  • Question 3/10
    4 / -1

    Which layer of the cardiac wall is made up of cardiac muscle fibers?

    Solutions

    The heart muscles line the myocardium, or middle layer of the heart walls, and are responsible for the contractile function of the cardiac pump. Composed of cardiomyocytes, the heart muscle has distinctive cellular and physiological features allowing it to generate force to maintain adequate tissue and organ perfusion throughout the entire body. Heart muscle makes up one of the earliest functioning embryonic organs that continues to contract and beat from development throughout a lifetime.

    Hence, the correct option is (B).

     

  • Question 4/10
    4 / -1

    Which of the following bacterial diseases is symptomized by light-colored patches on the skin and total/partial loss of sensation?

    Solutions

    Leprosy is caused by infection with the bacterium Mycobacterium leprae. It mainly affects the skin, eyes, nose and peripheral nerves.

    Symptoms include light-colored or red skin patches with reduced sensation, numbness and weakness in hands and feet.

    Hence, the correct option is (A).

     

  • Question 5/10
    4 / -1

    Which condition is not satisfied by an ideal solution?

    Solutions

    An ideal solution is as followed:

    Volume change (ΔV) of mixing should be zero.

    Heat change (ΔH) on mixing should be zero.

    Obey Raoult’s law at every range of concentration.

    ΔmixS = 0 is not satisfied.

    Hence, the correct option is (B).

     

  • Question 6/10
    4 / -1

    On a winter day when the atmospheric temperature drops to −10∘C, ice forms on the surface of a lake. (a) Calculate the rate of increase of thickness of the ice when 10 cm of ice is already formed, (b) Calculate the total time taken in forming 10 cm of ice. Assume that the temperature of the entire water reaches 0∘C before the ice starts forming. Density of water =1000 kg/m latent heat of fusion of ice =(3.36×10 J/kg and thermal conductivity of ice =1.7 W/m−∘C. Neglect the expansion of water on freezing.

    Solutions

    Hence, the correct option is (D).

     

  • Question 7/10
    4 / -1

    A 4.5 cm long needle is placed 12 cm away from a convex mirror of focal length 15 cm. Give the location of the image and the magnification.

    Solutions

    Hence, the image of the needle is 6.7cm away from the mirror. Also, it is on the other side of the mirror. The image size is given by the magnification formula. 

    The height of the image is 2.5 cm. The positive sign indicates that the image is erect, virtual, and diminished. If the needle is moved farther from the mirror, the size of the image will reduce gradually.

    Hence, the correct option is (A).

     

  • Question 8/10
    4 / -1

    The resistance of 0.01 N solution of an electrolyte was found to be 210 ohm at 298 K, using a conductivity cell of cell constant 0.66 cm−1. The equivalent conductance of the solution is:

    Solutions

     

  • Question 9/10
    4 / -1

    Which of the following will not show geometrical isomerism?

    Solutions

    The compound can show geometrical isomerism when both the valencies of double-bonded carbon are satisfied by different groups. In 2,3-Dimethylpent-2-ene both valencies of second carbon are satisfied by the methyl group. Hence it will not show geometrical isomerism.

    Hence, the correct option is (A).

     

  • Question 10/10
    4 / -1

    Which one of the following statements is incorrect?

    Solutions

    Ammonotelic organisms include aquatic animals which excrete nitrogenous waste as soluble ammonia. Ureotelic organisms include fish, amphibians, mammals including humans which excrete excess nitrogen as urea. While the uricotelic organisms include reptiles like lizards, snakes and birds which excrete uric acid or salts that are least soluble in water.

    Hence, the correct option is (D).
