Написать о чем текст, 2-3 предложения кратко Embryology is the study of the formation of life, part of the studies with which developmental biology is concerned. Developmental biology examines how all forms of life begin, and how they develop into fully formed and functioning organisms. Embryology looks at the very beginning of life from the one-celled organism, egg or sperm. Embryologists examine fertilization and track the development of the embryo until it bears a resemblance to its progenitors. For example, in human conception, embryologists would be interested in both sperm and egg, and the meeting of the two, and then would follow egg implantation and the growth of an embryo until it reaches the fetal stage. So in humans, the study of an embryo would last until about the second month of a pregnancy. 109 Aristotle was one of the first to champion the theory of epigenesis, the concept that life forms develop into complex organisms from fertilization. This was not a popular concept and was largely discarded in favor of the theory of preformation, which suggested that each human sperm was already a person in waiting. In the mid 18th century, Caspar Fredriech Wolff again set forth the concept of epigenesis. Through his study of chick embryos, Wolff realized that the body of an organism has stages of development. Through vivisection, he observed the complexity of specific organs and contended that their development could not simply have occurred spontaneously, but must have developed over time. Later scientists followed his studies, and with the development and subsequent improvements of the microscope, Wolff's theories were found to be quite accurate. Wolff is credited as the "Father of Embryology, " even though he did not first conceptualize epigenesis. Today, the theories of embryology are easier to prove because of the accuracy with which we can examine DNA codes within a cell. There are several practical applications of embryology in the modern world. Embryology has given doctors the tools to create fertilized eggs for in vitro implantation. Embryology can also identify risk factors for serious genetic conditions within the fertilized egg and select the most viable eggs for implantation. The study of embryology has led directly to the concept of cloning, either for a whole organism or parts of an organism.

Эмбриология - это изучение формирования жизни, часть исследований, которыми занимается биология развития. Биология развития изучает, как зарождаются все формы жизни и как они развиваются в полностью сформированные и функционирующие организмы.

Эмбриология рассматривает самое начало жизни от одноклеточного организма, яйцеклетки или спермы. Эмбриологи изучают оплодотворение и отслеживают развитие эмбриона, пока он не станет похож на своих предков. Например, при человеческом зачатии эмбриологов будут интересовать и сперма, и яйцеклетка, и их встреча, а затем проследить имплантацию яйцеклетки и рост эмбриона, пока он не достигнет стадии плода. Таким образом, на людях изучение эмбриона продлится примерно до второго месяца беременности.

Аристотель был одним из первых, кто отстаивал теорию эпигенеза, концепцию, согласно которой формы жизни развиваются в сложные организмы в результате оплодотворения. Это не было популярной концепцией и в значительной степени отвергалось в пользу теории преформации, которая предполагала, что каждый человеческий сперматозоид уже был ожидающим человеком. В середине 18 века Каспар Фредрих Вольф снова сформулировал концепцию эпигенеза. Изучая куриные эмбрионы, Вольф понял, что у организма есть стадии развития. Посредством вивисекции он наблюдал за сложностью определенных органов и утверждал, что их развитие не могло происходить просто спонтанно, а должно было развиваться с течением времени.

Позже ученые следили за его исследованиями, и с развитием и последующими усовершенствованиями микроскопа теории Вольфа оказались довольно точными. Вольф считается «отцом эмбриологии», хотя он не впервые концептуализировал эпигенез. Сегодня теории эмбриологии легче доказать из-за точности, с которой мы можем исследовать коды ДНК внутри клетки.

В современном мире существует несколько практических приложений эмбриологии. Эмбриология дала врачам инструменты для создания оплодотворенных яйцеклеток для имплантации in vitro. Эмбриология также может выявить факторы риска серьезных генетических заболеваний в оплодотворенной яйцеклетке и выбрать наиболее жизне яйца для имплантации. Изучение эмбриологии привело непосредственно к концепции клонирования либо целого организма, либо его частей.

Music for me is magical. Music is what motivates not only me, but also each of us and in some cases makes us move forward to meet our goals. If you want everything to be good, then you need to listen to music. It relaxes, makes the body rest and not only the body, but the soul. With music, you can lie down and disappear. Music is something that can change your mood. You will feel like you are listening to music. It is very important to listen only to the music that makes you laugh. Dancing helps to Express emotions and show all the beauty of our body.

Perhaps the most important reason why I love dancing is self-expression. Each person dances in their own way, each has their own chips, their own improvisation, their own style. Through dance, you can convey any emotion, you can convey the deepest meaning that will make people think .
