Definition and Concept

What is Traffic: Traffic is the circulation of vehicles, movement of goods or people and, in computer terms, is the flow of data on the network . The word traffic derives from the verb traffic composed of the Latin lexicon trans- which means "from one side to another", Traffic, such as the circulation of vehicles, is used to define the amount of vehicles that exist, in a certain time frame, in roads used for any means of transport.The traffic is associated with traffic jams, which is defined as the impediment in movement due to vehicular congestion. Traffic, defined as the action of trafficking, is used as a definition of an illegal action of movement of goods, species or persons, such as traffic for example.drugs, arms trafficking, organ trafficking or human trafficking. See also: Influence trafficking Influence trafficking is a t term used to refer to the use of the situation of power in which an official or person is for his own benefit. Traffic in co...

The retina is a membrane located inside the eye that is responsible for receiving the images and, through the optic nerve, sending them to the Brain: Composed of different cell layers, the retina is a kind of tissue that is sensitive to luminosity and that generates various processes until it reaches the transmission of a nerve impulse to the brain. The photoreceptor cells (they get that name because they are sensitive to the light ) are the canes and the cones .It is estimated that, in the human being, the retina houses more than 126 million of these cells, mostly canes.The latter, precisely, come into operation when there is low luminosity and provide a vision in black and white.The cones, on the other hand, act in good light conditions and allow the development of color vision. The outer layer of l the retina is called pigmentary epithelium .Then other layers appear until it reaches the so-called internal limiting layer , which divides the retina from the v...

Molar volume is a concept that is used in the field of chemistry .The notion is used to name the volume occupied by one mole of a substance , using as a reference unit the cubic meter per mole . As can be seen if we analyze the definition mentioned in the first To understand what the molar volume is, it is essential to understand what the volume is and that it is a mol . The idea of ​​volume can be used in different ways: in this case, we are interested in its meaning as the magnitude indicated by the space occupied by something high, wide and long (that is, in three dimensions).A mole, meanwhile, is a unit that allows the measurement of the existing amount of an element that has a weight equivalent to its molecular weight reflected in grams. It is important to mention that, in every substance, one mole houses a amount of mass that is contained in 6.022 x 10 raised to 23 molecules .This figure (6.022 x 10 raised to 23) is called Avogadro number and is the amoun...

The animal is classified as the animal whose diet is based on herbs or, in a broader sense, on the vegetables in general .In some cases, species that are mainly herbivores can consume some animal proteins through eggs or insects. In the group of herbivorous animals, we can find granivoros (they feed mostly on seeds), folivoros (leaves are their main food), frugivoros (centered on fruits) and xilofagos (its diet is based on wood).It is important to note that many times the herbivorous diet changes during the year according to the season. The ruminants are an example of herbivorous animals.These mammals are characterized by digestion in two steps: at first they consume the plants and then They develop rumination, which is based on the regurgitation of semi-digested food to chew it again, add more saliva and undo it.The cows , the deer , the goats and the sheep are ruminants and therefore herbivorous. The food chain , also known as food chain or food cha...

Wind (from Latin ventus ) is the air current that occurs in the atmosphere due to natural causes.Wind, therefore therefore, it is a meteorological phenomenon originated in the movements of rotation and translation of the Earth. Solar radiation generates differences of temperature in the atmosphere, which gives rise to the differences of pressure and air movement.Wind speed can be used to produce energy (known as wind ), although it is also dangerous, since it can demolish buildings of great size.The displacement of seeds and the erosion are other consequences of the action of the winds. For example: “There is a lot of wind; it is not convenient to go sailing ” , “ The day is beautiful: lots of sun and no wind ” . The first instrument created to detect the direction in which the wind blows was the weather vane .It is a rotating device with a cross that indicates the cardinal points and which is usually located in high places.A more advanced tool is the anemometer ...

Preservation is a term related to the verb preserve , whose etymology takes us to the Latin praeservāre .of preserving consists of taking care of, protecting or defending something in advance , with the aim of avoiding possible damage or deterioration. The preservation , so therefore, it can be developed in various fields and in different ways to preserve the qualities or integrity of things.There are, for example, several rules and laws of preservation that seek to protect natural attractions and historic buildings. When what is sought is to take care of a park, a mountain, a river or any other natural area, the preservation is aimed at avoiding the contaminating activities that damage the ecosystem .Thus, a preservation law may prohibit the development of mining activity in a mountain or camping or camps in a forest.It is necessary to establish that there are many measures and actions that can be carried out and carried out to achieve the preservation of the enviro...

What is an Operating System: An operating system is a program that are part of the basic software of an informatic device that is used to manage the hardware and allows the operation of certain applications . The operating system is responsible for transmitting information between programs of application and physical resources (such as peripheral devices).The type of operating system determines the use of applications, because many of them require the use of a certain operating system. This term is appropriate English operating system .In Spanish it sometimes appears with the acronym SO . Some examples of operating systems are Microsoft Windows, GNU/Linux and Mac OS X.They all have different versions that have different features and functions. See also System. Graphic environment operating system An operating system of graphic environment is a type of operating system based on images and icons.for having a more intuitive character for the user through the...

What is Tundra: Tundra is called the coldest biome on the planet that are those areas of flat land with little vegetation , whose climate is subglacial, the subsoils are frozen and there is an absence of trees. The word tundra derives from the Russian word тундра , which means "plain without trees." The ecosystems that make up the tundra are located at different geographical points and share very similar general characteristics.The tundras occupy approximately one tenth of the firm territory of the planet . In the northern hemisphere the tundras meet in Siberia, northern Canada, Alaska, the European Arctic coast and south of Greenland and in the southern hemisphere the tundras are in the southernmost tip of Argentina, Chile, subantartic islands and in some areas of northern Antarctica that are close to the sea ​​level. Hence the different ecosystems that exist in tundras have c general characteristics that facilitate their identification, among them, low tempera...

We explain that it is a community in biology, examples and characteristics, that it is individual and species, community and population. A biological community is made up of populations that share the same habitat. What is a biological community? In biology, there is talk of community or biological community, but also of ecological community, biotic community or biocenosis, to refer to the total set of organisms of various species that coexist and interrelate in a same biotope or habitat, in which they find the environmental conditions to guarantee their survival. In other terms, it is a set of different populations that share life in a geographical region and influenced by environmental physical elements such as temperature, humidity, the amount of sunlight, etc.Biological communities can be found in the most diverse and reconditos of habitats, since life on the planet is very scattered and adapted to each environment, even when it comes to microorganisms in the intestine of...
