A force can be applied to a moving object to change its direction, speed but not the mass and volume. A snake eats other animals hence it is called a predator. All the given animals are egg laying animals. The water drops on the inside edge of the glass is formed by the condensation of the rising steam. An opossum that eats fruit and fish is an omnivore. Topsoil is rich in humus. In the given figure mushroom that is labelled as ‘1’ is a fungi. The force that pulls the iron block downwards and causes the spring to stretch is due to gravitational force. Thick skin of cactus plant helps to save water by preventing transpiration in plants. The life cycle of housefly starts with eggs → larva → pupa → adult. Rain, snow and sleet are the forms of precipitation of water. The leaf help the plant in synthesizing the food by using light energy. The part labelled as ‘X’ is stomata. Stomata help in exchange of gases. During photosynthesis and respiration it gives out oxygen and during respiration it takes in oxygen from air. Mangroves grow in marshy soil. The roots of a plant need air to breathe hence the grow above the soil to take in air. Air is made up of 78% nitrogen, 21% oxygen and 1% water vapour and other gases (including 0.03% carbon dioxide). The seashells are a part of the molluses. Molluscs are the animals living in the sea. In electric iron electrical energy is converted to heat energy. In a radio electrical energy is changed to sound energy and in a tube light electrical energy is converted to light energy. Young of cockroach are called nymph. Nymph resemble their parents in their external structures. The products of respiration that are released during exhalation are carbon dioxide and water vapour. Therefore the air that we exhale contains water vapour which will condense when it touches the window.

The roots of plants absorbs water and mineral salts from the soil. The cycle of a butterfly starts from an egg. After 10 days a caterpillar will hatch out which feeds on leaves and breaths through its spiracles. In this stage the caterpillar will moult around 5 or 6 times and 3 weeks from that will become a pupa. The pupa weaves itself inside a cocoon where it develops into a butterfly this process is called Metamorphosis. The part labeled ii is the small intestine. This is where majority of the digested food is absorbed. The small intestine as you can see from the picture is the longest tract in the digestive tract.

Tadpole in their early development breathes with their gills. Hydrophytes are plants that live in water as their habitat. Calcium, phosphorous and Vitamin D are important for the development of our bones and teeth. Vitamin D helps to regulate the absorption of calcium and phosphorous in our body. Canine teeth are used to tear food into pieces.

Malaria is spread by the mosquito The label X refers to the liver. It produce bile which helps to break down fats into fatty acids.

Sundew plant is an autotroph and insectivorous plant. It grows in mineral deficient soil, hence it feeds on insects to get required minerals. Mushroom is an example of a fungus or nongreenplant.
