Mercury's atmosphere is included in the list of characteristics studied by Mariner 10 and Messenger. The thin air shell of the planet, like everything on it, is subject to the constant influence of the luminary. The sun is the main factor determining and shaping the features of the atmosphere of Mercury. Last modified: 2025-01-23 12:01

Bioecology is the foundation of all areas of study of ecology, because nature is our habitat. And in order for people to live fully, our habitat must be in order: the air must be clean, the water must be clear, the land fertile, and the flora and fauna he althy. If we do not take care of nature, we will not be able to fully live. Respect for the environment is the key to the existence of all life on Earth. Every person should know this.

Gram stain is widely used in microbiology as it is one of the easiest ways to differentiate bacteria based on the composition of their cell wall. According to Gram, all bacteria can be divided into gram-positive (Gram (+)) and gram-negative (Gram (-)). The Gram stain method was developed in 1884, and has not lost popularity since then, although it has been repeatedly modified. Last modified: 2025-01-23 12:01

Great Soviet scientists are known all over the world. One of them is Andrei Dmitrievich Sakharov, a physicist and public figure. He was one of the first to write works on the implementation of a thermonuclear reaction, therefore it is believed that Sakharov is the "father" of the hydrogen bomb in our country.

In the system of rotation of two cosmic bodies of a certain mass, there are points in space, by placing any object of small mass in which, you can fix it in a stationary position relative to these two bodies of rotation. These points are called Lagrange points. The article will discuss how they are used by humans. Last modified: 2025-01-23 12:01

"Nature abhors a void" is an expression that everyone must have heard more than once. But at the same time, its meaning, and even more so the author, is not known to everyone. Essays written on the topic “Nature does not tolerate emptiness”, as a rule, are considered in a moral aspect. Although in fact this expression is directly related to science - physics.

Food is one of the main components of human he alth, activity and quality of life in general. But, in order for all these components to be realized, it is necessary to supply the body with certain substances in a timely manner in the correct ratio and volume. Nutritional physiology studies what the composition of a person’s diet should be: how much protein, fat, carbohydrates, vitamins and minerals he needs for optimal functioning, what rules and norms must be observed.

The embryonic period of development of vertebrates is characterized by the formation of temporary (provisional) organs, such as chorion, yolk sac, allantois and amnion. The last of them plays one of the most important roles, as it produces amniotic fluid, which provides an environment for the development of the body. Last modified: 2025-01-23 12:01

Just 100 years ago, people could not even dream of being able to travel through the air, overcoming great distances at high speed. Moreover, the idea of a man in space seemed something fantastic. At the present time, the fact of half a year's stay of people in orbit is already commonplace. Often on TV screens they talk about people conquering space. But sometimes they are called astronauts, and sometimes they are called cosmonauts. What is the difference?. Last modified: 2025-01-23 12:01

Multidimensional scaling is a method of data analysis and visualization using the location of points corresponding to the studied (scaled) objects in a space of lesser dimension than the feature space of objects. The points are placed so that the pairwise distances between them in the new space differ as little as possible from the empirically measured distances in the feature space of the objects under study.
