Which one of the following is the correct matching of three items and their grouping category?

  1. array|l|l| Items & Group \ Ilium, ischium, pubis & Coxal bones of pelvic girdle \ array
  2. array|l|l| Items & Group \ Actin, myosin, rhodopsin & Muscle proteins \ array
  3. array|l|l| Items & Group \ Cytosine, uracil, thiamine & Pyrimidines \ array
  4. array|l|l| Items & Group \ Malleus, incus, cochlea & Ear ossicles \ array

Answer

(1) array|l|l| Items & Group \ Ilium, ischium, pubis & Coxal bones of pelvic girdle \ array

Solution

As per NCERT, the pelvic girdle consists of two coxal bones; each coxal bone is formed by the fusion of three bones: ilium, ischium and pubis.

(2) Rhodopsin is a visual pigment of the rods of the eye, not a muscle protein (actin and myosin are).

(3) Thiamine is vitamin B1, not a nitrogen base; the pyrimidines are cytosine, uracil and thymine.

(4) The ear ossicles are malleus, incus and stapes; cochlea is a coiled part of the inner ear.

Ilium, ischium, pubis – coxal bones of pelvic girdle is the correct matching.
