Cotyledons or seed leaves supply food, radicle forms the root and plumule forms leaves and stem. All these animals are adapted to fly. Pumice is an igneous rock. The process of changing solid form to liquid is called melting. The correct combination is: p-ii, q-iii, r-i. Pulley is used for lifting heavy objects, wedge, for cutting objects and screw for fixing two objects. The seeds of guava do not get digested by the animals and are passed out through faeces.

For the proper functioning of our body and for remaining healthy, rest, balanced diet and exercise are needed. Pumice is porous or full of holes. Oxygen gas is used up in the burning of things and in the process of respiration and release carbon dioxide. Hinge joint allows movement in only one direction. The movement is similar to the movement of a door on its hinges. Example : The knee and elbow joints. A tortise has a hard and strong shell. Which protects it from it predators. Air is necessary for burning. The lever, inclined plane, pulley, screw, wheel and axle are simple machines. The seedling was dispersed by water. The function of the skeletal system is to give support and shape to the body. Deficiency of vitamin ‘C’ causes scurvy. Lunar eclipse occurs on a full moon day. Spiders make cobwebs to catch its prey. A sea-saw is a firstclass lever. Radicle grows first it is the first root of the plant. Skull protects the brain. It is also called cranium or bony box.

The given figure is that of a satellite. In the first class lever, fulcrum is between load and effort. In the given figure R is called the condensed stem. It grows into a new plant. Nerve cell, vertebral column and brain are the parts of central nervous system. The volume of water displaced by the object = 10 ml. When water is heated, it changes to water vapour. The process is called evaporation. The hump of camel stores fat. For a fire to start it need a substance that can burn, air and kindling temperature. Land dwelling are called terrestrial. There are 206 bones in our body. The moon is a natural satellite of the earth. The square represents load, the triangle represents fulcrum and the arrow represents effort. The correct food chain based on the given figure is : seeds  chicken  eagle. Pellagra is a vitamin deficiency disease. Obsidian is smooth and glassy. It is black and dark coloured and is used in jewellery and ornaments. The moon undergoes periodic changes and reflect sunlight. The animal that Anish saw is a fish. The correct combination is: Potato - eyes, onion- bulbs, bryophyllum-leaves, Rosestem cutting. Vitamin ‘C’ prevents the disease bleeding gums or scurvy. Carbohydrates and proteins are missing in Arun’s breakfast. The changing shapes of the moon are called phases. Pliers, scissors and hand pump are examples of the first order levers. A fish uses fins to move in water.
