Answer 1

the organism is cockroach.

Six legs of the insect help it to walk, and two pairs of wings help it to fly. Cockroach does not possess any bones making up endoskeleton.

Exoskeleton is the hard and stiff outer covering of the body made up of chitin. Exoskeleton is a jointed structure which helps in the movement of the body. A cockroach moves its legs with the help of muscles near the limbs. It uses its breast muscles to move its wings and fly. A cockroach can walk, fly and even climb.
