Every living organism in our nature is unique and cannot be repeated. In the process of reproduction, the mother’s cell merges with the father’s cell and one completely new cell is formed – the zygote. This process is accompanied by a random exchange of genes and chromosomes, which cannot be controlled from the outside. In a cat, during the process of ovulation, several small eggs mature, which are fertilized by several sperm. Ultimately, several kittens are born at a time, each with their own unique structure and characteristics.
One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
