1. Nature gave birth to human beings, indicating that it respects human behavior. On the contrary, human beings should respect nature more. On the surface, people are born of their parents. In fact, only when nature has the photon information of human beings can human embryos absorb this photon information from nature and grow into adults, that is, parents. At the same time, nature has completed the excitation of dark matter in embryos.

There are 45336 species of vertebrates in nature, including birds 1244 species and fish 3862 species. There are more than 3 million species of insects, and only 1 10,000 species have been confirmed.

Nature is a kind of natural resources, so people and nature should respect each other, maintain the attitude of cherishing and caring, make proper use of nature and prevent its destruction, so that the living environment is beautiful and the natural resources are inexhaustible, just like the mother and son are close and harmonious.

Therefore, the richness of information about nature can only be described as vast as a sea of smoke, and its complexity is not described by 30 thousand words or a few people.

There are all kinds of creatures in nature, including plants, animals, bacteria and fungi. At the same time, nature is also a place containing various ecosystems.

The elements of nature are divided into light, darkness, water, fire, wind, thunder and earth, which means that nature controls the balance of these things.

The spiritual influence of nature is the first in time and the most important in place. Every day, the sun; After sunset, at night, with her stars. The wind has been blowing; Grass grows forever. Every day, men and women are talking, watching and being watched. Of all people, that image attracts philosophers the most.

He must decide its value in his own mind. What is nature in his eyes? This web of God, its incomprehensible coherence, has never started or ended. It is always a circulating force, returning to itself.

This is similar to his own mind, and he will never find its beginning and end-so complete and infinite. The glory of nature has been shining so far. There is a universe above the universe, which radiates like light, upward and downward, without center and circumference-whether it is gathering or dispersing, nature is eager to express itself to people's hearts.

Biology:

Biology is a subject that studies life phenomena and the laws of life activities. It is the foundation of agronomy, forestry, medicine and environmental science. The development of society, the progress of human civilization and the improvement of personal life quality all depend on the development and application of biology. Biology is too important for human beings! Living things are indispensable everywhere.

The origin of life is an important contemporary scientific topic, but it is also the most basic biological problem that is still poorly understood so far. There have been various hypotheses about the origin of life in history, such as "God created" (that life was created by God or God) and "spontaneous occurrence" (that life, especially simple life, naturally occurred from inanimate matter). Most of these hypotheses are speculative and have been rejected by people.

According to the research papers published at the international conference on the origin of life held in recent years, contemporary hypotheses about the origin of life can be divided into two categories: one is chemical evolution theory, and the other is cosmic embryo species theory. Cell totipotency is not the basis of animal cell culture, but the theoretical basis of plant cell culture. The theoretical basis of animal cell culture is cell proliferation.
