Modification is what? Types of modifications

With the word "modification" we come across quite often and approximately understand what it is about. But there are a huge number 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 change of some 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 a modification in this case is, for example, the lubrication of the door, because of which it ceases to creak when opened. This is a household example. If we take more scientific types of modification, then this may be a change in the genetic code of the embryo, so that the body that grows from it acquires new signs.
2. Natural processes. Modification can occur naturally. For example, water has the property of freezing, as a result of which 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 engineering

In the technique, modification is the creation of an improved version based on the old version of the device. It can be a mobile phone, a computer or any other device. For example, all versions of the iPhone are in fact modifications of the very first version of this smartphone. But most often this term is implied not so much an updated version of the device that came out 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 occurs due to the impact of human 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 purposeful or spontaneous change in the characteristics of a living being, not associated with a genetic mutation of the DNA code. It can be provoked both with the help of natural mechanisms, and under the direct impact 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 on the conditions as a whole, and each attribute associated with the genotype due to the modification variability can manifest itself differently at different temperatures and air composition in the phenotype (appearance, in other words, simply). 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.
