If the head of the cockroach is removed, it may live for a few days because:
| 1. | The cockroach does not have a nervous system |
| 2. | The head holds a small proportion of the nervous system while the rest is situated along the ventral part of its body |
| 3. | The head holds 1/3rd of the 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 |

1. Antennae
2. Compound eyes
3. Anal cerci
4. Both(1) & (2)
