Explanation:
SNAKE = Snakes have a cylindrical, long body with scales. The body has numerous muscles and vertebrae. Snakes slither on land to move by drawing on their bellies. They form loops while moving. Each loop of the snake gives it a forward push by pressing against the ground and helps the snake to move forward.
FISH = The locomotion in fishes is because of their fins, body muscles and tail. The body of the fish is adapted for swimming in water. They have a streamlined, spindle-shaped body which is covered with scales. This body structure offers the least resistance to the flow of water and makes them swim easier. T During swimming, the front part of the body curves on one side and tail on the opposite side.
BIRD = Bird have a thing called a “skeletal structure”; this serves as a framework to give the bird it’s basic shape and also handily provides attachment points for “muscles” and “tendons”. Birds also have a “nervous system” controlled from a central command center known as the “brain” which sends messages to the muscles, causing them to contract or relax. it is this contraction or relaxation of the muscles that provides “movement”
COCKROACH = A cockroach’s body is covered with a hard outer skeleton. Cockroaches have a pair of antennae that help them smell things. They also have a pair of cerci that can detect the slightest of movements and warn them of any danger from behind. Like all insects, cockroaches have three pairs of legs. They walk in a very interesting manner, moving three legs at a time. Let us suppose the dots represent the legs.
COW = DON'T KNOW
MONKEY = DON' KNOW
