Answer:
Such answers need to be attempted on your own. Here is a sample for your reference:
Did you know that bees perform an intricate dance when they find food. Amazing isn't it? Also, primates groom each other. Such kind of curiosities are endless and scientists are rethinking what they know about animal behavior, even in its most basic forms. Here, we would be discussing one such animal behavior. Cockroaches can live without their head for weeks. After their head is cut off, their open circulatory system (with much less pressure and no huge network of blood vessels) allows their neck to simply seal off by clotting.
In addition, roaches breathe through spiracles, or tiny holes. Their brain does not control this breathing and their blood does not carry oxygen throughout the body. The spiracles pipe air directly to the tissues. So while all breathing would cease in a human or mammal, breathing does not cease without the head of a roach. Finally, since cockroaches are cold blooded animals, they can survive with very little food. The headless roach can go for weeks as long as it conserves energy and does not get eaten. Of course, eventually it will end up dieing of starvation or perhaps a mold or bacterial infection.
