The different methods of asexual reproduction:
- Vegetative propagation- It is a type of asexual reproduction in which new plants are produced from roots, stems, leaves and buds.
- Budding- In organisms such as Hydra, a bud develops as an outgrowth at one specific site.
- These buds develop into tiny individuals and when fully mature, detach from the parent body and become new independent individuals.
- Spore formation- The spores are asexual reproductive bodies.
- Each spore is covered by a hard protective coat to withstand unfavourable conditions such as high temperature and low humidity.
- So they can survive for a long time. Under favourable conditions, a spore germinates and develops into a new individual.

Cyclone is formed over tropical seas. Winds from opposite directions meet. This air is heated by the warm seas and so evaporates moisture from the ocean. This warm air rises up rapidly, cools and condenses to form clouds and produces an area of very low pressure. When moisture and air mix, it makes a collection of thunderstorms from which a cyclone can develop.

The exhaled air contains less oxygen and more carbon dioxide than the inhaled air because the air in the lungs becomes humidified with water before it is exhaled.

Materials:
- 1.5V Battery
- Wire
- Compass
Procedure:
- Place the compass on a horizontal surface.
- Connect the wire to both ends of the battery.
- Place the middle of the wire directly over the compass, parallel to the initial orientation of the needle.
- Observe the needle deflect to one direction.
- Now flip the wire over so the current flows in the opposite direction and place it over the compass again.
- The needle will deflect in the other direction.
Explanation:
A current will carry with it its own magnetic field. The magnetic field lines form concentric circles around the wire so that the field points in one direction above the wire and the opposite direction below the wire. Using the right-hand grip rule, where one holds his hands as though he is gripping something with his thumb pointing in the direction of current flow, his fingers will curl in a way as to indicate the direction of the magnetic field. This is also the direction in which the needle deflects.

Rain water and the water from water bodies on earth’s surface pass through the soil by the process of infiltration. The infiltrated water then gets accumulated in the aquifer deep under the ground. There are some layers of impermeable rocks which prevent the water in the aquifer from seeping down further. In this way, the ground water is recharged.

An electric bulb is used for light but it also gives heat. This is not desirable. This results in the wastage of electricity. This wastage can be reduced by using fluorescent tube lights (CFLs) in place of the bulbs. They work on chemical effect of electricity and not on heating effect of electricity. Thus they do not consume more energy as electric bulbs. Thus they are very cost efficient.
