A row is formed from the provision u organization online of various elements. It is a succession of human beings, animals or objects where each member is placed behind the other.

For example: “The line of young people waiting for the stadium doors to open is getting longer”, “I like to walk under the row of trees of this avenue ”, “The row of lights that shone in the distance allowed him to discover that the town was closer than he thought”.
To formation of soldiers, military vehicles or artillery pieces that are located one behind the other It is also called row. In combat, the row is constituted perpendicular to the front. If the soldiers stand next to each other, they talk about row .
The observation of colonies Ant is an activity that is fascinating for many people, regardless of their level of knowledge or professional occupation. One of the first things we notice in their social behavior is that these living beings move in long rows, and this leads us to wonder why they do it.
The shortest answer is that the ants are guided using pheromone trails left by others who have plotted the path and reinforced by the whole group. It is a series of chemical tracks that have a particular smell and that serve to maintain order. In general, their long expeditions aim at the search for food, and thanks to this mechanism they can move away without fear of being lost.
The process that takes place for the creation of this row begins when the solitary ants leave the nest in search of new shelters, other colonies to enslave them or food, among other resources. They do not need the pheromone trail to return to their nest, but they create it once they find something of interest, so that the army they recruit goes directly to the collection point and does not divert or pass through a zone dangerous.
Different external factors can cause the "destruction" of the path drawn by the first: the passage of an animal through this area, a rockfall or the action harmful and intentional of a human being. Although in some cases the ants are not able to orient themselves again, while the damage is not too great they are able to reconnect both sections and continue with their work.
A row, on the other hand, is a instrument that the workers of the metallurgy and the silversmith's to achieve the reduction of metals to threads. This device consists of a plate that has small holes, through which the metal is passed to obtain the threads.
For the zoology Finally, the rows are appendices of the spiders that provide support to the glands responsible for producing the liquid that, when dried, forms the silk. These rows appear in pairs and are around the anus.
The number of rows depends on the species spider Usually each spider has six rows, although some have two and others, four. This part of its legs is the one that most characterizes this class of arthropods that attracts both human beings, either because it is fascinating or because of the fear it causes in the face of potential bites, some of them deadly. According to certain studies, it is possible that spiders used these rows for a long time to help them climb and that throughout their evolution they have become the source of thread for their tissues.
