Whether it is snow-capped mountains, endless green grasslands, surging rivers, surging seas, golden fields, noisy cities, and smoke-filled villages, in these beautiful natural pictures In the world, there are living things everywhere, and the rich and colorful nature is intoxicating. However, do you understand the various mysteries of nature?
Let’s start with what biology is!
There are all kinds of objects in nature, which can be divided into two categories: non-living things and living things according to their properties. Things without living phenomena such as water, air, and rocks are called non-living things, also known as non-living nature; animals, plants, and microorganisms with living phenomena are called living things, also called living nature. And living things gradually changed from non-living things over a long period of time.
Since there are rich and colorful creatures on the earth, biology is inseparable. Next, let’s talk about what biology is. Simply put, “biology” is the science that studies the life phenomena and laws of life activities of organisms. It is one of the basic subjects of natural science. Regarding biology, humans have been understanding, studying and utilizing it for thousands of years, and many scientists such as Darwin in the UK, Schwann in Germany, Michurin in the Soviet Union, etc. have emerged. There are some famous explorers like Li Shizhen of China, but overall, the development of biology is still relatively slow, generally just staying in the description of biological phenomena. It was not until 1953 that Watson and Crick discovered the genetic material DNA. after the double helix structure. Over the past 50 years, biological science has developed rapidly and made many gratifying achievements. For example, Li Guanqi, a high-tech inventor in Huaxian County, Henan Province, used biotechnology to invent "soy protein modified fiber", which is called the "eighth largest man-made fiber" in the world after polyester, nylon, acrylic fiber, vinylon, etc. by the international textile industry. Known as "artificial cashmere". It is mainly extracted from soybean meal and is still a waste material. This patent is worth 2 billion yuan.

From this, we can see that the development of biology is rapid. The relationship between biology and production practice is very close. It plays an important role in the development of productivity. A huge boost. Therefore, the development prospects of biology are bright. Many scientists predict that the 21st century will be the century of biology. The impact of biology on the 21st century is as great as the impact of physics and chemistry on the 20th century. Based on the current development level of biological science, it is foreseeable that a large number of new results may appear by then. The number of plants used by humans can increase from the current thousands to tens of thousands. The emergence of new varieties of crops will further increase the yield and protein content of crops such as wheat and rice. Cows can grow as big as elephants. Milk production is greatly increased. As the secrets of photosynthesis are revealed, artificial synthesis will surely become a reality, and synthesizing edible proteins will not be a problem; organ transplantation is no longer a new thing, and artificial organs such as artificial hearts and artificial lungs will become popular; and longevity will be extended. With the advent of drugs, people can live to 120 to 150 years old. As the mystery of the origin of life is revealed, advanced technologies such as "cloning" are being further developed.
Precisely because biological science has such a close relationship with human beings, biology is listed as one of the required courses in middle schools. Classmates, let us study biology seriously and join the ranks of life science research. Here you will discover a world of infinite mysteries that plays a significant role in human development
