Answer 2

Answer:

Ans- The three pairs of legs present in a cockroach allow it to run very fast. The body of a cockroach is covered with a hard exoskeleton made up of different units joined together. This helps the cockroach in its movement.

Ans- The ball and socket joint (or spheroid joint) is a type of synovial joint in which the ball-shaped surface of one rounded bone fits into the cup-like depression of another bone. The distal bone is capable of motion around an indefinite number of axes, which have one common center.

Ans- The hinge joints of the body include the elbow, knee, interphalangeal (IP) joints of the hand and foot and the tibiotalar joint of the ankle.
