Modification is what? Types of modifications

With the word "modification" we come acrossoften enough and approximately understand what it is about. But there are a lot of meanings of this term, united by a universal definition. In this article, the phenomenon of modification from the point of view of various spheres of human life and activity will be considered, and examples of manifestation of this concept in science and life will be given. So, a modification is a modification of an object with parallel acquisition of new functions or properties.

Causes of modifications

The reasons for the modifications may be as follows:

1. Human interference.An example of the modification in this case is, for example, lubrication door, because of which the one stop squeak when opened. This is a household example. If we take a more scientific types of modifications, it could be a change in the genetic code of the embryo, so that it grew out of the body finds new signs.
2. Natural processes.Modification can occur naturally. For example, water has the property of freezing, so it acquires new properties - it becomes hard, cold and, falling in the form of hail, can spoil the crop grown by the farmer with incredible efforts.
3. Pathological processes that do not depend on a person.Modification of a genetic code by a virus or a cancerous tumor can lead to the onset of diseases. Even one small cell, if it is not controlled by the body, begins to perform another function, working on the virus, multiplying it. The same applies to, for example, the negative effects of ultraviolet radiation on living organisms.

Modification in technology

In the technique, modification is a creation based onThe old version of the device is an improved version of it. It can be a mobile phone, a computer or any other device. For example, all versions of the iPhone are in fact the modifications of the very first version of this smartphone. But most often this term is implied not so much as an updated version of the device, published in a year, but rather a model with slightly different characteristics. In this case, the Gsmart Roma R2 + phone can serve as an example of the modification, which has improved characteristics in the background of the model without the plus sign.

Modification of polymers

This process is due to exposurehuman factors on the object. Modification of polymers is a complex of actions aimed at changing certain properties of these materials, due to which they are given special physical and mechanical characteristics. One of the most popular ways to effect such a change is chlorination, whereby polymers can become resistant to light, heat, or chemical attack.

Modification in biology and breeding

In these spheres, modification is a purposefulor a spontaneous change in the characteristics of a living being, not associated with a genetic mutation of the DNA code. It can be provoked both by natural mechanisms and under the direct influence of human factors. Simply put, modification is a change in the characteristics of the body, which improves its ability to adapt to the conditions of the surrounding world.

These characteristics depend, in general, on the conditions, andeach attribute associated with the genotype due to the modification variability can at different temperatures, the air composition appear in the phenotype (appearance, simply put) differently. It turns out a certain modification of the body in the form that the scientist wants to receive, or the organism modifies itself for a more rapid adaptation to the environment.
