  • Acne or acne vulgaris is a long term skin condition when hair follicles are clogged with dead skin cells and oil from skin. It is characterized by pimples, blackheads and possible scarring.

    It affects areas of the skin with a relatively high number of oil glands , including the face, upper part of the chest, and back.

    Genetics and bacterial infections are the main contributing factors for acne. It can be treated by medications such as benzoyl peroxide, retinoids, etc.

  • Participatory democracy emphasizes the broad participation of constituents in the direction and operation of political systems. Etymological roots of democracy (Greek demos and kratos) imply that the people are in power and thus that all democracies are participatory.

  • Answers:
  • The genetic code is the set of rules by which information encoded within genetic material (DNA or mRNA sequences) is translated into proteins by living cells.

    Translation is accomplished by the ribosome, which links amino acids in an order specified by mRNA, using transfer RNA (tRNA) molecules to carry amino acids and to read the mRNA three nucleotides at a time.

    The genetic code is highly similar among all organisms and can be expressed in a simple table with 64 entries.

  • 2x/3y = 400        eqn 1                      4y / 5 = 460         eqn 2

    2x = 400 x 3 x y                                 4y = 460 x 5

    x = (400 x 3 x y) / 2                             y =  (2300) /4 = 575 

                         x = 600 x 575

  • Answers:
  • Osmosis is a phenomenon where in there happens to be  a movement of solvent particles ( ie. molecules  / ion )  from a solution  of lower concentration  to that of higher concentration when the two are separated from each other by a semipermeable membrane.

    while , 

    Osmotic pressure  is the pressure built up between the two solution undergoing osmosis . It is  caused due to a difference of vapour pressures  between  both the solutions.
