Skeletal system is the system of the body which provides framework to the body. It supports, protects the body and allows the movement of various body parts. It includes bones, tendons, ligaments, cartilages, joints, etc. Digestive system helps in food digestion, circulatory in the circulation of blood and excretory in the removal of wastes.

X-ray is the technique by which one can observe the shape and structure of the bones whereas ECG checks the functioning of heart and blood test to check the level or the components of the blood.

The body of earth worm is soft as it does not have bones. It moves by the peristaltic action of muscles and affixes itself to the ground with the help of large number of tiny bristles. Also, its body secretes a slimy substances to help the movement.

Snail is an animal which is having outer skeleton called shell or the lid. It has a foot made of strong muscles. It is a very slow moving animal with a wavy motion.

If we touch our back below the neck in the middle, then we can feel a hard bony structure known as back bone. It helps to maintain the erect posture of body.

Rib cage is a hard bony structure, in the cavity of which the lungs rest. Lungs are the delicate organs and stay protected in this hard bony structure. Thus, ribcage protect delicate organs.

So, it is the neck gliding joint which is a mismatched pair.

Birds are the living organisms which can fly in the air and walk on the ground. For this they need to have lighter bodies with light and hollow bones. For flying, they have strong shoulders bones and a streamlined body to act against air currents.

Birds are the living organisms which can fly in the air and walk on the ground. Pigeon, vulture and sparrow are not at all adapted to swim in water but birds like swans and ducks are adapted for the same.

Different organisms have different mode of movement from one place to another. E.g. fish swims in water, human beings walk, monkey jump and snake slithers to move from one place to another. Slithering is the zig-zag movement of the whole body of snake.

Cockroaches have outer skeleton made of different jointed units. Snakes have a long single back bone. Fishes have stream lined body to swim well in water. In birds, the forelimbs are modified as wings.

Different organisms have different mode of movement from one place to another. E.g. fish swims in water, human beings walk, monkey jump and snake slithers to move from one place to another. Slithering is the zig-zag movement of the whole body of snake. Also earthworm moves by crawling and cockroach by climbing. So, it is snakes: walking which is a mismatched pair.

Snail is an animal which is with outer skeleton called shell or the lid. It has a foot made of strong muscles. It is a very slow moving animal with a wavy motion.

Streamlined body is found in organisms which are adapted for flying or swimming. It helps them to cut through air and water currents. Snake is a terrestrial animal which does not have a streamlined body.

Birds are the living organisms which can fly in air and walk on the ground. The bones of the bird limbs are typical for walking and perching, and the bony parts of forelimbs are modified into wings.

Earthworms eat their way through the soil. Its body then throws away the undigested part of materials that it eats. This activity of earthworms makes the soil more useful for plants.

Fish swim in water as they have a streamlined body. They also need to maintain balance so that they may not sink down. For this purpose, they have fins which act as balancer organ for them.

Birds are the living organisms which can fly in the air and walk on the ground. The bones of the bird hindlimbs are typical for walking and perching and the bony part of forelimbs are modified as wings.

Snakes slither to move from one place to another. Slithering is the zigzag movement of the whole body of snake.
