describe a skeleton of a cockroach
Answers
Answer:
Most cockroaches have three joints on each leg, which means they have 18 knees! The skeleton is made of a hard substance called chitin. When a skeleton is on the outside, it is called an exoskeleton. The exoskeleton supports and protects the roach's insides. Exoskeleton is common to arthropod like cockroach.
Cockroaches are arthropods, and just like all arthropods, they don't have a spine, making them invertebrates. In fact, cockroaches don't have any other bones either. But in order for a cockroach's muscles to properly operate their legs, wings and other moving parts, they have to be attached to something rigid.
The skeleton is made of a hard substance called chitin. When a skeleton is on the outside, it is called an exoskeleton. The exoskeleton supports and protects the roach’s insides. Because it is hard, the exoskeleton cannot grow. To get around this problem, a cockroach sheds its exoskeleton several times per year. Then its body grows quickly before the new exoskeleton forms. When the exoskeleton has just been shed, the cockroach’s skin appears very light. Then, after about eight hours, the skin becomes dark again.
