What is the core?

The term 'core' is used in the science in several different ways, although all cases refer to the critical structure found in the center of something. In fact, the word "core" means "core" or "core" and comes from an ancient Greek word, which means "matrix". In general, the core is so critical that the surrounding structure without it cannot survive. In fact, the cell nucleus is one of the defining characteristics of eukaryotes because the structure allows cells and organisms to achieve a very high level of complexity. This cell -free structure contains DNA organism and the core is responsible for the regulation of gene expression, duplicating DNA as needed and passing hereditary features, in the case of eggs and sperm cells. Forest and complex cell interiors. Like other parts of the cell, the nuclei are connected to the cell cycle, which includes the reproduction of the cell and the possible cell death as different components of the cellular age. For colored microscopes, cell nuclei are usually very easy to see thanksThe fact that DNA can be colored with a specific color to excel and highlight this structure in the cell.

In physics, the core is the core of the atom. Atomic nuclei are extremely dense and contain most of the atom weight in the form of particles known as protons and neutrons. Electrons of orbit around the atomic core. Depending on the layout of the particles in the atom, it may be extremely stable or unstable, in which case the atom can obtain or lose particles and generate radioactivity. The "kernel" application to physical data at the beginning of the 20th century, when physicists began to explore atoms and elements in favor of the new technology that allowed such a study.

Because the cores are associated with a "control center" or "core" in the sciences, people sometimes refer to central structures or events as cores. For example, someone could say that the boiler room is the "core" of the campus heating system. An older sense of 'core' orThe "seed" can also be referred to when people discuss key items or events that lead to larger events such as a work of art that form the basis of the collection, or a protest that triggers widespread social awareness of political problem.
