Science, as one of the forms of knowledge and explanation of the world, is constantly evolving: the number of its branches and directions is steadily growing. This trend is especially clearly demonstrated by the development of social sciences, which open up more and more new facets of the life of modern society. What are they? What is the subject of their study? Read more about this in the article

A modern museum can hardly be called an institution that simply presents some exhibits. Now this is a whole laboratory, and the items here are nothing more than equipment. It is these characteristics that distinguish Quarks, the Museum of Entertaining Sciences, from other institutions that perform similar functions

Earth is our beautiful blue home in the vast harsh universe that stretches across the vast expanses of our space. Our planet is amazing and unique, it has ideally formed conditions for the origin of life of organic origin. An important role was played by the chemical composition, the presence of the atmosphere and the magnetic field for its appearance and prosperity in all varieties
Heredity is the most important ability of living organisms to transfer all their properties and functionality to new generations. And the defining feature of heredity is combinative variability, with the help of which living organisms are endowed with purely individual qualities and a unique gene combination. Without this ability, the evolutionary process and natural selection would not be possible
Propionic acid bacteria, the properties of which will be discussed below, are united by the genus Propionibacterium. It, in turn, belongs to the Propionibacteriaceae family. Let us consider in more detail what characteristics propionic acid bacteria have, where these microorganisms are contained and used
All matter in the Universe consists of small building blocks - atoms. And the electronic configuration of this structural unit of any substance forms its individual qualities. Penetration into the secrets of the nuclear-electronic model of the atom gave world science a grandiose impetus to accelerate on the thorny path of progress
Few people think every day about what exactly to eat and how to optimally build their diet. Unfortunately, only people with serious he alth problems most often think about nutrition. Everyone knows that the diet should be protein. What is this substance?
Complex metabolic reactions in plants are explained by the special structure of their body parts: root, stem, leaves, called vegetative organs. They are responsible for the processes of photosynthesis, transpiration, osmosis. In this work, we will study the structure and functions of such plant elements as root hairs. These are important structures that determine the absorption of water and mineral s alts from the soil
In this article, we will look at how glucose is oxidized. Carbohydrates are compounds of the polyhydroxycarbonyl type, as well as their derivatives. Characteristic features - the presence of aldehyde or ketone groups and at least two hydroxyl groups
Today we will talk about LII them. Gromov. We will talk about what this institution is like, dive a little into its history, and also learn about the most significant incidents. Read all about it in the article below
There are many classes of different animals in nature. One of them is fish. Many people do not even suspect that these representatives of the animal world have a brain. Read about its structure and features in the article
What is the Raven matrix? It is believed that this is just an intelligence test, but is it really so? In the article we will talk about the test and its legendary creator
In nature, there are living organisms whose dimensions are so small that it is simply impossible to see them with the naked eye. They are observed by scientists only with the help of microscopes of high magnification
Molecular biology studies the structure and functions of molecules of organic substances that make up the living cells of plants, animals and humans. A special place among them is given to a group of compounds called nucleic (nuclear) acids
We so often hear about nerves, we say that these cells do not regenerate, many times we notice how we do something completely automatically…Understand the actions of our brain, understand how nervous tissue is arranged, structure and functions this amazing system, you can by reading this article
Amazing energy stations of the cell - who are they? How mitochondria are arranged, what they are used to doing and what danger their DNA poses - all this in our article
Translation is an important and difficult process to understand. To explain protein biosynthesis concisely and clearly, one must start from the basics of cell structure and biochemistry. But we tried to tell as simply as possible about how protein chains are created in any living cell
Protein synthesis is a very important process for every cell. The functions of proteins are diverse; the life of any organism depends on their proper functioning. The article describes the main components of the protein synthesis system and the stages of translation
One of the most ancient and important sciences for people is anatomy. And not only the one that concerns directly the person. Methods for studying the anatomy of plants and animals also made it possible to understand a lot about the structure of the world
The largest number of muscles is located on the face. Their main distinguishing characteristic is that they have only one fixed end on the bone structures, and the second is woven into soft tissues, forming a mobile point of attachment
Every living organism goes through a certain life cycle: from conception (laying) to death (death), and plants are no exception. Their distinguishing feature is the process of reproduction, which consists in the alternation of sporophyte and gametophyte
The tertiary structure of a protein is the way in which a polypeptide chain is folded in three-dimensional space. This conformation arises due to the formation of chemical bonds between amino acid radicals remote from each other. This process is carried out with the participation of the molecular mechanisms of the cell and plays a huge role in giving proteins functional activity
The type of chemical bond in a substance determines its structure and properties. From them, in turn, depends on its role in the environment and the possibility of using it in various areas of human life, from gardening to space exploration
Anatomical topography is a section of anatomy that studies the layered structure of human body regions, the location of organs relative to each other, holotopy and skeletopy, as well as blood supply and lymph flow during normal development of the body and in pathology, taking into account all age and gender characteristics person. This section of anatomy is of great importance for medicine, as it represents the theoretical basis for operative surgery
A complex protein, in addition to the protein component itself, contains an additional group of a different nature (prosthetic). Carbohydrates, lipids, metals, phosphoric acid residues, nucleic acids act as this component. What is the difference between simple proteins and complex proteins, what types of these substances are divided into, and what are their features, this article will tell
Entire books have been written about different types of energy. Many scientists conduct different experiments in this area. For humanity, this is one of the most topical issues. With the development of technology, we have become almost completely dependent on power sources. Therefore, many are interested in what energy is, what it is and how it is used

Gnomon is an ancient astronomical instrument that allows you to determine the angular height of the sun by the smallest length of the shadow of its column. Such peculiar watches were created a long time ago, they helped to determine the time on a sunny day. The sun here just plays a key role, more precisely, the shadow from it. In other words, the gnomon is the simplest sundial
