why do the insects for example cockroach die when lying down for a one day
Answers
Explanation:
Due to their open circulatory system, and the fact that they breathe through little holes in each of their body segments, they are not dependent on the mouth or head to breathe. The roach only dies because without a mouth, it can't drink water and dies of thirst.
Answer:
There are two basic reasons.
Cockroaches have a slightly rounded and greasy back, and a flat body that helps them squeeze and hide in narrow cracks and crevices. Their long legs give them a high center of gravity, meaning they carry most of their weight around their backs. When a cockroach is dying of old age, its high center of gravity pulls its back toward the floor, and its rounded back and weakened muscles prevent it from righting itself, particularly on smooth surfaces.
