Mouse

This article is regarding to computer input device. For the animal, see mouse. For other uses, see mouse (disambiguation).

A contemporary computer mouse, with the most common normal features: two buttons and a scroll wheel. In computing, a mouse (plural mice or mouses) functions as a pointing device by detect two-dimensional motion relative to its supporting surface. Physically, a mouse consists of a small case, held beneath of the user's hands, with one or more buttons. It sometimes features other elements, such as "wheels", which let the user to perform various system-dependent operations, or extra buttons or features can add more control or dimensional input. The mouse's motion classically translates into the motion of a pointer on a display, which allows for fine control of a Graphical User Interface.

The name mouse, originate at the Stanford Research Institute, derives from the similarity of early models (which had a cord attached to the rear part of the device, suggesting the idea of a tail) to the common mouse.

Pulses

Pulses are defined by the Food and Agricultural Organization of the United Nations (FAO) as yearly leguminous crops yielding from one to twelve grains or seeds of variable size, shape and color surrounded by a pod. Pulses being used for food and animal feed.

The term pulses, as used by the FAO, are kept for crops harvested solely for the dry grain. This therefore excludes green beans and green peas, which are measured vegetable crops. Also barred crops which are mainly grown for oil extraction oilseeds like soybeans and peanuts, and crops which are used exclusively for sowing (clovers, alfalfa).

Pulses are main food crops due to their high protein and necessary amino acid content. Like many leguminous crops, pulses play a key role in crop turning round due to their capability to fix nitrogen.

Chocolate

Chocolate comprises a number of raw and process foods that are formed from the seed of the tropical cacao tree. Native to lowland tropical South America, cacao has been sophisticated for three millennia in Central America and Mexico, with its earliest recognized use about 1100 BC. All of the Mesoamerican peoples made chocolate beverages, as well as the Maya and Aztecs, who made it into a beverage known as xocolātl, a Nahuatl word meaning "bitter water". The seeds of the cacao tree have a controlling bitter taste, and must be fermented to develop the flavor. After being roasted and ground, the ensuing products are known as chocolate or cocoa.

Much of the chocolate inspired today is made into bars that combine with cocoa solids, fats like cocoa butter, and sugar. Chocolate has twist into one of the most popular flavors in the world. A chocolate lover is also called as "chocoholics." Gifts of frustrated wrapped chocolate molded into different shapes has become traditional on certain holidays: chocolate bunnies and eggs are popular on Easter, coins on Hanukkah, Santa Claus and further holiday symbols on Christmas, and hearts on Valentine's Day. Chocolate is also used in cold and hot beverages, to make chocolate milk and cocoa.

Earth

Earth (pronounced /'???/) is the third planet from the Sun and is the major of the terrestrial planets in the Solar System, in both diameter and mass. It is also referred to as the Earth, Planet Earth, and the World, and in several contexts, Gaia and Terra.

Home to millions of species including humans, Earth is the only place in the world where life is known to exist. Scientific evidence indicates that the planet formed 4.54 billion years ago, and life appear on its surface within a billion years. Since then, Earth's biosphere has considerably altered the atmosphere and other abiotic conditions on the planet, enable the proliferation of aerobic organisms as well as the formation of the ozone layer which, jointly with Earth's magnetic field, blocks harmful emission, permitting life on land.

Earth's outer surface is divided into several rigid segments, or tectonic plates, that regularly travel across the surface over periods of many millions of years. About 71% of the surface is enclosed with salt-water oceans, the remainder consisting of continents and islands; liquid water, necessary for all known life, is not known to exist on any other planet's surface. Earth's interior remains active, with a thick layer of comparatively solid mantle, a liquid outer core that generates a magnetic field, and a solid iron inside the core.
