  • Question 1/5
    1 / -0.33
    Pancreatic juice contains more than one enzyme. Which among the following combination is

    Correct -

    Solutions

    The pancreatic juice contains enzymes that complete the digestion of starch called pancreatic amylase. It also contains pancreatic enzymes that complete the digestion of protein called Trypsin, chymotrypsin and carboxypeptidase.

  • Question 2/5
    1 / -0.33
    Which of the following is not true for Hormones?
    Solutions

    * Hormones are specifically acting organic compounds secreted by Endocrine Glands directly into the blood stream from where these are transported to the target organ.

    * These can induce or inhibit various biochemical processes and are not available again after the process is over.

    * There are four main classes of hormones, i.e., protein and polypeptide hormones, steroid hormones, monoamines and lipid-based hormones.

  • Question 3/5
    1 / -0.33
    Which of the following is the process of bending of light rays after entering a medium where its speed is different.
    Solutions
     Refraction is the process of bending of light rays after entering a medium where its speed is different. During the process, if a ray of light passes from a rarer medium to a denser medium, then it bends towards the normal to the boundary between the two mediums. The number of bending rays depends upon the indices of refraction of the two media. Hence, option A is correct.
  • Question 4/5
    1 / -0.33

    Which of the following is the correct formula for Lorentz force?

    Solutions

     The Lorentz force (or electromagnetic force) is the combination of electric and magnetic force on a point charge due to electromagnetic fields. A particle of charge q moving with a velocity v in an electric field E and a magnetic field B experiences a force of F = qE + qv * B {\displaystyle \mathbf {F} =q\,\mathbf {E} +q\,\mathbf {v} \times \mathbf {B} }

    Hence, option D is correct.

     

  • Question 5/5
    1 / -0.33

    Which of the following Statement is not correct about the diamond?

    Solutions

     Diamond is a well-known allotrope of carbon. The hardness, extremely high refractive index, and high dispersion of light make diamond useful for industrial applications and for jewelry. Diamond is the hardest known natural mineral. This makes it an excellent abrasive and makes it hold polish and luster extremely well. No known naturally occurring substance can cut or scratch diamond, except another diamond. In diamond form, carbon is one of the costliest elements. Hence, option D is correct.
