Life is the characteristic feature of biological prakriyasampanna physical sattaguloke distinguishes, for example, cellular signal and sbayansampurnabhabe survival mechanism, the objects of this gunabaligulo, there are these qualities destroyed , so it is not so, or their qualities never happened, and usually These are classified as inanimate objects . Life exists in many forms, such as plants, animals, fungi , protists , archaea and bacteria . Sometimes this standard of appearance can be unequivocally expressed , as well as viruses , viruses ., Or may or may not interpret potential life as a "living" organism.
Biology is a major part of science for the study of life , although many other branches of science are involved.
Defining life is somewhat controversial. The current definition, however, is that the organism adheres to homeostasis , which is composed of cells , transforms, grows , adapts to the environment , reacts to stimuli, and is capable of reproduction . There are also many more definitions of biology, and there are some exceptional examples of life, such as viruses . Attempts have been made for a long time to understand what life means, and many theories have been provided about the properties and evolution of living things. One of the few major theories is materialism , a belief that everything is said to have originated from an object and that life is a complex form of it; Another theoryHyalomorphism is a belief that everything is a combination of matter and size, and the form of living things is its soul; Another theory spontaneity is a belief that life evolves recurrently from inanimate matter; And animism is a belief that living things have a "way of life" or "particle of life". In the modern definition, it has become more complicated to receive data from different scientific disciplines. Biophysicists have provided many definitions based on chemical processes. There are several living process theories - the Gaia conclusion is a concept where the earth itself is actually awake. Another theory is that life is an ecosystemA feature; And another theory is that life is a complex system of biology, a branch of mathematical biology. The origin of life is described as the natural emergence of inanimate substances, such as common organic compounds . One of the characteristics that almost all organisms have in common is that they contain certain basic chemical elements that are required to carry out the normal activities of biochemistry .
Some time after the formation of the Earth 4.54 billion years ago, the formation of the oceans 4.41 billion years ago , the existence of the first life on Earth was found about 4.26 billion years ago . Current life on Earth probably originated from the RNA world , although RNA -based life is not the first. The process by which life originated remains unknown today, although many conclusions have been drawn and are often based on Miller-Uri observations. The first living thing to be found was the bacterial microflora, a microbial organism in a 3.45 billion year old Australian rock.The report has been published. [5] [6] In July 2016, scientists reported the discovery of a set of 355 genes , all of which are said to be the last universal ancestor of the same gene .
It has changed the environment on the basis of geological time since the beginning of life on earth . To survive in most ecosystems , life has had to adapt to a variety of conditions. Some microorganisms , such as Extremophil, can grow in physically and biochemically hostile environments, causing harm to other life on Earth. Aristotle was the first person to classify living things. Carl Linnaeus later developed his own method of binomial nomenclature for taxonomic species Invented. Also new masses and divisions of life are discovered, such as cells and microorganisms, which bring about dramatic changes in the structure of living things. Considered to be the smallest unit and structure of cell life. There are two types of cells, pre- centrifugal and eukaryotic . Both the membrane to the cytoplasm composed of many bayomalikiula, such as protein and nucleic acid. The process of cell division involves generating new cells. In this process a mother cell divides into two or more offspring cells.
Although so far life has been found only on earth , it is not limited to this. Many scientists are thinking about the existence of extraterrestrial life . Artificial life is a computerized replica or man-made reconstruction of any form of life, used to experiment with methods related to natural life. Death is the permanent end of all biological processes in life . Extinction is a process in which a particular mass, species becomes completely extinct. Fossils are the remaining parts of an organism.
