What is the meaning of the Life Life topic?

The power of life or the thing about life.

Life is an object with proprioceptive perception and the ability to perceive the external environment that is compatible with this proprioceptive ability. This is life, otherwise it is a stone or a kind of nothingness.

Life is not just a plant or an animal as we understand it, life can be any substance, and life can also be an ethereal soul. The concept of any matter includes both physical matter and virtual matter, and of course the soul.

Animals are life, people are also life, and people are distinguished from animals because of their strong cognitive ability. Plants are also living beings, and plants are distinguished from animals and humans because of their lack of perception and mobility.

Modern science's understanding of the origin of life

Everything in the universe is ever-changing, and the natural world is gorgeous and colorful, which is nothing more than the distinction between living and non-living things. From the point of view of modern science, life is just a form of material movement, it is only composed of proteins, nucleic acids.

The material system composed of biomolecules such as lipids is far less subtle than the understanding of life by the ancients.

This dark blue for us to live in.

The planets were formed about 4.5 billion to 6 billion years ago, when the earth was only a drop in the ocean in the endless universe, and it was a dead world, with only a hot atmosphere and primordial oceans. However, with the changes of the earth over hundreds of millions of years, the substances that make up life, and the proteins and hydrocarbons that are also the basic elements of life.

Born of conception. In this way, life has the most basic material basis. Over a long period of time, a primitive life form, a primitive cell, gradually emerged. Its appearance also marks the end of the first life.

1. Life is a Chinese word, pinyin is shēng mìng. One refers to the survival of organisms, the ability of organisms to move; the second refers to the fundamental conditions for the survival of things; Three-fingered fate; Four fingers to live; The five fingers refer to living things, especially animals; Six-fingered life; Seven fingers biologically believe that life is a form in which proteins exist.

2. The connotation of life refers to the existence of a certain number of self-growth, reproduction, feeling, will, evolution, interaction and other rich possibilities in the process of development and change of the universe, which can also include the self-replicating amino acid structure produced by biochemical reactions, as well as fungi, bacteria, plants, animals (demolition and attack on humans), as far as the future development is concerned, artificial manufacturing or facilitating machines are complex to a certain extent, Phenomena that possess certain basic cavity properties that conform to the connotation of life may also be included in the category of life, including human-machine hybrids, pure free will, artificial intelligence robots, etc.

<>1. The meaning of life is a philosophical question that deconstructs the purpose and meaning of human existence. This concept is expressed through a number of related questions, such as: "Why am I here?" and "What is life?"

What is the true meaning of life? ”。It has also been the subject of scientific and theological reflection throughout history.

Our ancestors also gave many diverse answers in different cultural environments and ideological backgrounds.

2. The meaning of life often intersects with philosophy, religious concepts such as existence, consciousness (self-realization), happiness, etc., and will also involve some other fields, such as symbols, substance, values, purposes, morality, good and evil, freedom and will, forgiveness (voluntariness), the concept of God, the existence of God, the soul, the afterlife, etc. However, the relationship with science is not so direct, and science generally sets certain backgrounds and parameters to describe the facts related to the universe on topics related to it.

1. Engels scientifically defined life for the first time In the second half of the 19th century, Engels gave a definition of life: "Life is the mode of existence of the proteosome, and the basic factor of this mode of existence lies in the continuous metabolism of the external nature around it, and as soon as this metabolism stops, life will stop with it, and the result is the decomposition of proteins." "Engels' definition of life reveals to a certain extent the material basis of life, that is, the proteosome with metabolic functions.

For 100 years, this definition has been a guide to the idea of life.

2. Mankind's New Understanding of Life Since the 20th century, natural science has developed rapidly, and the relevant sciences that study life have successively entered the molecular level. Modern science has proved that after removing water from living cells, about 90% are proteins, nucleic acids, sugars, and lipids, among which proteins and nucleic acids are the most important. Biological proteins are composed of 20 heavy amino acids, which play an important role in the catalysis of nucleic acid metabolism, the regulation and control of metabolism, and the memory and recognition functions of higher animals.

Nucleic acids are composed of bases, pentose, phosphoric acid. Depending on the pentose sugar contained in the nucleic acid, the nucleic acid can be divided into ribonucleic acid (RNA) and deoxyribonucleic acid (DNA).Nucleic acids control the synthesis of proteins and determine the properties of proteins.

It can be said that proteins and nucleic acids are interdependent and interact with each other, making the living body a unity.

3. Different definitions of life It should be said that life is a phenomenon that is difficult to define, and each professional research tends to define it in its own terms:

1) Physiological definition For example, life is defined as a system with functions such as eating, metabolism, excretion, respiration, movement, growth, reproduction, and reactivity. But some bacteria don't breathe.

2) Definition of metabolism Living systems have interfaces and often exchange substances with the outside world without changing their own properties.

3) Biochemical Definition Living systems contain nucleic acids that store genetic information and enzyme proteins that regulate metabolism. However, a virus-like organism is known to have no nucleic acids.

4) Genetics defines a system that evolves through gene duplication, mutation, and natural selection.

Life is a process of interaction between heaven and earth. Heaven and earth interact, one yin and one yang; Back and forth. The yang is moving, so the loss is the living, and the loss is not lost, that is, death.

The yin is quiet, so it is to gain for a living, and to get nothing is to die. Therefore, the ancients said that the yang is easy to live, and the yin is easy to kill.
