The content of biochemistry mainly included the chemical composition, structure, and function of biological substances, as well as the rules of chemical metabolism and regulation in the process of life. There were many biochemical methods, and the commonly used techniques included: 1. ** Separation and purification of substances **: This was the prerequisite for studying the structure and function of biological molecules. The whole process could be divided into material selection.(Choose the target material or tissue with high content of required components, rich sources, simple process, and low cost), cell crushing (Commonly used techniques include grinding with a refiner, high-speed tissue masher, repeated freeze-thaw, ultrasonic disruption, autolyzation, digestion with zymes, and treatment with a surfacing agent.), separation of subcellular organelle (Generally, it is prepared with different density grads and by differential centrifugal method), extraction (factors such as the nature of the solution, the pH value, the ion strength, the dielectrical constant, and the extraction temperature that affect the dissolution should be considered), separation and purification (according to the differences in the molecular size, the dissolution, the charging property, and the affinity of the substance, the methods such as organic solution settling, the crystallization, the purification, the purification, the 2. <strong></strong><strong></strong><strong></strong>There were three types of centrifugal machines: low-speed centrifugal machines (maximum speed no more than 6000 revolutions per minute), high-speed centrifugal machines (below 25000 revolutions per minute), and ultracentacles (up to 30000 revolutions per minute). 3. ** Separation **: Can be used to separate various biological molecules. 4. Electrophoretic method: It was also one of the commonly used techniques in biochemistry. 5. ** Spectral method **: It has a certain application in biochemical research. 6. ** Molecular hybrid technology **: It is of great significance to biochemical research. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

" Experience in the Science of Biology." Biology is like a door to a wonderful world. In the process of learning biology and science in junior high school, I gained many unique experiences. Living creatures allowed me to re-understand the Earth we live on. The Earth was a huge and complex ecosystem that provided a home for all kinds of creatures. From the deep ocean to the towering mountains, from the vast forest to the boundless desert, there were traces of life in every corner. For example, cacti could survive in harsh environments such as deserts, while penguins could adapt to the cold of the Antarctic ice sheet. This showed that creatures had strong adaptability. Biology was very scientific, not only in its rigorous knowledge system, but also in the methods used by biologists to study biological phenomena. For example, when studying biological evolution, scientists discovered the phenomenon of identical organs by comparing the structures of different species of organisms. Although their appearance and functions were different, their anatomical structures were similar. This proved that organisms with identical organs evolved from a common primitive ancestor. At the same time, the development of molecular biology provided a new way for the study of biological evolution. By determining the structure of protein and DNA, one could determine the kinship between organisms. In the process of studying biology, I also deeply experienced the tenacity and fragility of life. The Yimi Flower grew in the Gobi Desert of Africa. It only accumulated nutrients for a short 48 hours of blooming before withering. Although its life was short, it was incomparably gorgeous. This allowed me to see the tenacity of life. The growth of dandelion seeds required a suitable environment. If it was too dry, wet, cold, or hot, it would not grow, which reflected the fragility of life. The study of biological knowledge made me understand the importance of protecting the environment. Living creatures and the environment were mutually dependent, and human activities had a huge impact on the living environment of living creatures. We should respect every life and protect the biological variety. Only in this way can we maintain the balance of the earth's ecology. Biology science was like a key that unlocked my passion for exploring the mysteries of life. It also made me fear nature more and love life more. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The development of biology abroad was as follows: In ancient times, 460 - 370 B.C., Hippocrates and others established Greek medicine and proposed the theory of health and illness. 384 - 322 B.C. The Greek scholar, aristotle, described and categorized more than 500 animals. He also dissected some animals and observed their embryonic development. He wrote related books, which were the results of early zoological research. 372 - 287 B.C. Greek scholar Theophragaster explained the basic differences between animal and plant structures and described more than 500 kinds of plants. He wrote related books. 23 - 79 AD Roman naturalist Pliny the Elder wrote 37 volumes of Nature, which summarized the natural knowledge and technology of the time. 129 - 200 AD Roman doctors systemized Greek anatomy and medical knowledge, establishing the human physiological anatomy. In the 19th century, the British biologist Charles Darwin proposed the theory of evolution, which had a profound impact on biology. Since the 20th century, the discovery of DNA structure had laid the foundation for modern genetics, and the human gene sequence had provided the possibility of customized medicine. In modern times, for example, in dealing with plastic pollution, foreign research found that the bacteria in the saliva of wax insects could decompose plastic, and more than 30,000 kinds of bacteria that could digest 10 different types of plastic were identified. There was also research on the petase produced by the Japanese bacteria. In terms of synthetic biology, foreign countries had already taken the lead. The global industrial output value could reach more than 220 billion US dollars, and there were results in some fields such as biomedicine, food and beverage, and some were in the research and development stage or small-scale trial production stage. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

There was a story in the reference materials. The situation of the 39-year-old Xiao Yun could be said to be the reincarnation of her biological mother.

If you were using headphones to control the phone for photography, take a Huawei phone as an example. After connecting the headphones through Bluetooth, you could turn on the camera on the phone and press the earphone answer button to take a photo. In addition, when taking selfies, you can use the volume button of the headset to control the shutter of the phone to take photos, and continuous pressing can achieve continuous shooting. If it was shooting directly with headphones, Apple was researching the integration of camera technology into AirPods. Its project was to explore the integration of low-resolution camera sensors into headphones, so that headphones could play the role of a camera for shooting. However, the project was still in its infancy, and the specific details and release time were not clear. At present, there was no information related to the shooting function of other earphones that were already on the market. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
