Metabolism comprises of two major parts; one is anabolism and the other catabolism. The Catabolism process is the action of the set of metabolic pathways that breaks down molecules into smaller units that are either oxidized to release energy or used in other anabolic reactions. The process involves the breakdown of large molecules such as polysaccharides, lipids, nucleic acids and proteins into smaller units like monosaccharides, fatty acids, nucleotides, and amino acids, respectively.

• In an uncharged electroscope, the leaves hang straight down. • When a charged object touches the metal knob, electric charges travel, down the road & into the leaves. • The leaves spread apart, indicating the presence of an electric charge. • Since the charge on both leaves is the same leaves repel each other & spread out.. HOPE IT HELPS YOU.....??

Ionic compounds are compounds made up of ions. These ions are atoms that gain or lose electrons, giving them a net positive or negative charge. Metals tend to lose electrons, so they become cations and have a net positive charge. Ionic compounds have high points of melting and boiling and appear to be strong and brittle. Ions may be single atoms, such as sodium and chlorine in common table salt (sodium chloride) or more complex groups such as calcium carbonate.

 James mill was a great philosopher and economist.He wanted to study the history of India.But as we all know studying such a elongated history wont be easy.So he divided the history or past into 3 periods-Hindu,Muslim and British.This is called Periodisation.But due many reasons it is not accepted and so now our history is divided as ancient history,midieval history and the modern history.

A positive object brought near a neutral insulator polarizes its molecules. There is a slight shift in the distribution of the electrons orbiting the molecule, with unlike charges being brought nearer and like charges moved away. Since the electrostatic force decreases with distance, there is a net attraction. Insulators tend to be at opposite ends of the triboelectric series while metals tend to be more in the center. So, insulators tend to become more easily charged when rubbed by almost anything material that's more in the middle of the triboelectric series.

Decibel (dB), unit for expressing the ratio between two physical quantities, usually amounts of acoustic or electric power, or for measuring the relative loudness of sounds. One decibel (0.1 bel) equals 10 times the common logarithm of the power ratio. The decibel (dB) is a logarithmic unit used to measure sound level. It is also widely used in electronics, signals and communication. The dB is a logarithmic way of describing a ratio. The ratio may be power, sound pressure, voltage or intensity or several other things.

Conservation of natural resources is now usually embraced in the broader conception of conserving the earth itself by protecting its capacity for self-renewal. Particularly complex are the problems of nonrenewable resources such as oil and coal (see energy, sources of ) and other minerals in great demand. Natural resources are available in fixed quantity and they are non – renewable, 8. Natural resources are getting scarce with the increasing population, so it is essential to conserve them. This empowers us as well as our future generation to utilise the natural resources to the full extent.

An airplane or aeroplane (informally plane) is a powered, fixed-wing aircraft that is propelled forward by thrust from a jet engine, propeller or rocket engine. ... The Wright brothers invented and flew the first airplane in 1903, recognized as "the first sustained and controlled heavier-than-air powered flight". In 1896, the newspapers were filled with accounts of flying machines. Wilbur and Orville noticed that all these primitive aircraft lacked suitable controls. They began to wonder how a pilot might balance an aircraft in the air, just as a cyclist balances his bicycle on the road.
