If the head of cockroach is removed, it may live for few days because

  1. the cockroach does not have nervous system.
  2. the head holds a small proportion of a nervous system while the rest is situated along the ventral part of its body.
  3. the head holds a 1/3rd of a nervous system while the rest is situated along the dorsal part of its body.
  4. the supra-oesophageal ganglia of the cockroach are situated in ventral part of abdomen.

Answer

(2) the head holds a small proportion of a nervous system while the rest is situated along the ventral part of its body.

Solution

As per NCERT, the nervous system of cockroach consists of a series of fused, segmentally arranged ganglia joined by paired longitudinal connectives on the ventral side.

Three ganglia lie in the thorax and six in the abdomen; the head holds only a bit of the nervous system (supra-oesophageal ganglion, the brain) while the rest lies along the ventral (belly-side) part of the body.

If the head of a cockroach is cut off, it can still live for about a week.
