Metabolism is the total set of chemical reactions that occur in living cells. These processes are the source of life, allowing cells to grow and reproduce, maintain their structures, and react to their environments. Metabolism is frequently divided into two categories. Catabolic reactions yield energy, an example being the stop working of food in cellular respiration. Anabolic reactions, on the other hand, use this energy to construct mechanism of cells such as proteins and nucleic acids.
The chemical reactions of metabolism are organized into metabolic pathways, in which one chemical is distorted into another by a series of enzymes. Enzymes are vital to metabolism because they allow cells to drive desirable but thermodynamically unfavorable reactions by combination them to favorable ones. Enzymes also agree to the regulation of metabolic pathways in response to changes in the cell's environment or signals from other cells.

Parrot
Parrots or psittacoses pronounced is an order namely Psittaciformes of birds that includes about 350 species. They are frequently grouped into two families: the Cacatuidae (cockatoo), and the Psittacidae (parrots), but one may find many variations. Some sources split parrots into three families. Citation needed the term "true parrot" is not used by the majority of bird keepers, biologists and lay people and is a source of confusion.
All members of the order have a usually erect stance and a characteristic curved beak shape with the upper mandible having slight mobility in the joint with the skull. All parrots are zygodactyls, with two toes at the front of each foot and two at the flipside, and all parrot eggs are white in color.

The Real Miracle
As far as Miracles is concern, turning salty seawater in to sweet water is quite amazing. Regardless of the scientific clarification being doled out—surplus freshwater flowing from the Mahim River into the sea—the thousand mass to Mahim Creek near the beachfront in Mumbai will pretty see the ‘transubstantiation’ as the deed of the late Haji Maqdoom Baba, whose shrine is in the area. Mass hysteria, of course, is only a term to clarify the hordes of believers filling plastic bottles and drinking the water. But the real miracle would be if those glugging the ‘miraculous’ water manages to flee succumbing to serious gastric illness.
The water of Mahim Creek, sweetened or otherwise, is dirty and would scandalize not only the likes of Sunita Narain of the Centre for Science and Environment. Maharashtra Chief Minister Vilasrao Deshmukh and officials of the Municipal Corporation of Greater Mumbai have already request to people not to drink the water. Industrial waste is not the finest ingredient for a miracle. But telling this to goggle-eyed people facing even more goggle-eyed TV cameras is as worthwhile as persuasive people that a Ganesh idol sipping milk is caused by suction and not godly lactose tolerance.
Fortunately, rumors of the sweetened water turning back to its original brackish form might stop a future surge. Now we only wait for the real miracle of no one complaining of sickness.

Technology
Mobile phones and the network they operate under vary significantly from provider to provider, and nation to nation. However, all of them communicate through electromagnetic microwaves with a cell site base station, the antennas of which are usually mounted on a tower, pole, or building.
The phones have a low-power transceiver that transmits voice and data to the nearest cell sites, usually 5 to 8 miles away. When the cellular phone or data device is turned on, it registers with the mobile telephone exchange, or switch, with its unique identifiers, and will then be alerted by the mobile switch when there is an incoming telephone call. The handset constantly listens for the strongest signal being received from the surrounding base stations. As the user moves around the network, the mobile device will "handoff" to various cell sites during calls, or while waiting between calls it will reselect cell sites.
Cell sites have relatively low-power radio transmitters which broadcast their presence and relay communications between the mobile handsets and the switch. The switch in turn connects the call to another subscriber of the same wireless service provider or to the public telephone network, which includes the networks of other wireless carriers.

Playground slides
Playground slides are found in parks, schools, playgrounds and backyards around the earth. Slides are constructed of either plastic or metal and they have a soft surface that is either straight or wavy/rippled. Slides are integral parts of playgrounds. The user, normally a child, climbs to the top of the slide via a steps or stairs and sits down on the top of slide and "slides" down the slide. Some slides are directly, others wind their way down. Slides come in different shapes, sizes and colors. Some slides are commercial, found in playground at parks and schools. Other slides are part of residential playgrounds.

CPU Socket
The term CPU socket is commonly used to describe the connector linking the motherboard to the CPU in certain types of desktop and server computers, particularly those compatible with the Intel x86 architecture.
Most CPU sockets and processors in use today are built around the pin grid array architecture, in which the pins on the base of the processor are inserted into the socket. To aid installation, zero insertion force sockets are usually used, allowing the processor to be inserted without any confrontation, while gripping the pins firmly once the processor is in place to ensure a reliable contact. In contrast to CPU sockets, slot-based processors and CPUs use a single-edged connection rather than a socket, and slot into the motherboard on their side. Slot architectures are not often used today.

Meteorology
Meteorology is the interdisciplinary scientific study of the ambiance that focuses on weather processes and forecasting. Meteorological phenomena are observable weather events which illuminate and are explained by the science of meteorology. Those actions are bound by the variables that exist in Earth's atmosphere. They are temperature, pressure, water vapor, and the gradients and interactions of each variable, and how they change in time. The majority of Earth's observed weather is located in the troposphere.

Traffic
Traffic is the movement of motorized vehicles, notarized vehicles and pedestrians on roads. Traffic laws are the laws which govern traffic and regulate vehicles, while rules of the road are both the laws and the informal rules that may have developed over time to facilitate the orderly and timely flow of traffic. Organized traffic normally has well-established priorities, lanes, right-of-way, and traffic control at intersections.

Krill fishery
Krill fishery is the profitable fishery of krill, small shrimp-like marine animals that live in the oceans world-wide. Estimates for how much krill there is vary wildly, depending on the methodology used. They range from 125–725 million tones of biomass globally. The total global harvest of krill from all fisheries amounts to 150 – 200,000 tones annually, mainly Antarctic krill (Euphausia superb) and North Pacific krill (E. Pacifica).
Krill are rich in protein (40% or more of dry weight) and lipids (about 20% in E. superb). Their exoskeleton amounts to some 2% of dry weight of chitin. They also contain traces of a wide array of hydrolytic enzymes such as proteases, carbohydrates, nucleases and phospholipids, which are intense in the digestive gland in the cephalothoraxes of the krill.

Freshwater prawn farm
A freshwater prawn farm is an aquaculture business designed to raise and produce freshwater prawn or shrimp1 for human consumption. Freshwater prawn farming shares many characteristics with, and many of the same problems as, marine shrimp farming. Unique problems are introduced by the developmental life cycle of the main species The global annual production of freshwater prawns (excluding crayfish and crabs) in 2003 was about 280,000 tons, of which China produced some 180,000 tons, followed by India and Thailand with some 35,000 tons each. Additionally, China produced about 370,000 tons of Chinese river crab

Solar System
Solar System consists of the Sun and the other space objects gravitationally bound to it: the eight planets, their 162 known moonsthree currently recognized dwarf planets (including Pluto) and their four known moons, and billions of small bodies. This last group includes asteroids, Kuiper belt objects, comets, meteoroids and interplanetary dust.
In wide terms, the charted regions of the Solar System consist of the Sun, four terrestrial inner planets, an asteroid belt composed of small rocky bodies, four gas giant outer planets, and a second belt, called the Kuiper belt, collected of icy objects. Beyond the Kuiper belt lies the scattered disc, the heliopause, and eventually the hypothetical Oort cloud.
In sort of their distances from the Sun, the planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Six of the eight planets are in turn orbited by natural satellites, usually termed "moons" after Earth's Moon, and each of the outer planets is encircled by planetary rings of dust and other particles. All the planets apart from Earth are named after gods and goddesses from Greco-Roman mythology. The three dwarf planets are Pluto, the largest known Kuiper belt object; Ceres, the largest object in the asteroid belt; and Eris, which lies in the scattered disc.

Fishing
Fishing is the activity of hunting for fish by hooking, trapping, or gathering. By extension, the term fishing is applied to pursuing other aquatic animals such as various types of shellfish, squid, octopus, turtles, frogs, and some edible marine invertebrates. The term fishing is not usually applied to pursuing aquatic mammals such as whales, where the term "whaling" is more appropriate. Fishing is an ancient and worldwide practice with various techniques and traditions and it has been transformed by modern technological developments. In addition to providing food through harvesting fish, modern fishing is both a recreational and professional sport.

Kolkata
Calcutta is the capital of the Indian state of West Bengal. It is located in eastern India on the east bank of the River Hooghly. The city has a population of almost 11 million, with an extended metropolitan population of over 14 million, making it the third-largest urban agglomeration and the third-largest city in India.
The city was very populated and served as the capital of India during the British Raj until 1911. Once the centre of modern education, science, culture and politics in India, Kolkata witnessed economic stagnation in the years following India's independence in 1947. However, since the year 2000, an economic rejuvenation has arrested the morbid decline, leading to a spurt in the city's growth. Like other large cities, Kolkata continues to struggle with urbanisation problems like poverty, pollution and traffic congestion.
A vibrant city with a distinct socio-political culture, Kolkata is noted for its revolutionary history, ranging from the Indian struggle for independence to the leftist and trade union movements.

Batteries
Electronic watches require electricity as a power source. Some mechanical movements and hybrid electronic-mechanical actions also require electricity. Usually the electricity is provided by a replaceable battery.
The first use of electrical power in watches was as replacement for the mainspring, in order to remove the need for winding. The first electrically-powered watch, the Hamilton Electric 500, was released in 1957 by the Hamilton Watch Company of Lancaster, Pennsylvania. Batteries for watches are specially designed for their purpose. They are very small and provide tiny amounts of power incessantly for very long periods. In most cases, replacing the battery requires a trip to a watch-repair shop or watch dealer; this is especially true for watches that are designed to be water-resistant, as special tools and procedures are required to ensure that the watch remains water-resistant after battery replacement. Silver-oxide and lithium batteries are popular today; mercury batteries, formerly quite common, are no longer used, for ecological reasons. Cheap batteries may be alkaline, of the same size as silver-oxide but providing shorter life.
