Natural selection is the guiding factor of evolution. It operates according to one mechanism - the strongest survive and leave behind offspring, i.e. the fittest individuals. However, depending on its effectiveness, direction, characteristics of the conditions for the existence of organisms, the forms of natural selection may be different. One of its forms is driving selection (directed), which contributes to the formation of new species of organisms in a changed environment. Last modified: 2025-01-23 12:01

In short, Pierre Simon Laplace is a scientist known in the scientific world as a mathematician, physicist and astronomer of the 19th century. He made a decisive contribution to the theory of planetary motion. But best of all, Laplace is remembered as one of the greatest scientists of all time and is called the "French Newton". In his writings, he applied Isaac Newton's theory of gravity to the entire solar system. His work on the theory of probability and statistics is considered groundbreaking and influenced a whole new generation of mathematicians. Last modified: 2025-01-23 12:01

What is science? Throughout our lives, we encounter this concept repeatedly. However, not everyone will be able to give a clear answer to this question. Science is the defining value of modern culture, its most dynamic component.

Signs that are useful for humans are not always needed and important for animals. Nature is also able to preserve some species, and eliminate some. This process is called natural selection, and interspecies struggle is one of the tools of this process. That is, animals compete with each other for food, water, territory, and so on. This is how species evolve, they are forced to adapt to some factor or simply disappear from the face of the Earth. Last modified: 2025-01-23 12:01

At the moment, science knows one hundred and five chemical elements, systematized in the form of a periodic table. The vast majority of them are classified as metals, which implies that these elements have special qualities. These are the so-called metallic properties. Such characteristics, first of all, include plasticity, increased thermal and electrical conductivity, the ability to form alloys, and a low value of the ionization potential.
