Chemistry and biology had many overlapping connections, involving the following knowledge of biology: 1. "Research on life phenomena at the molecular level": The study of life processes at the molecular level, such as biochemistry, which uses molecular methods to study, explain, and manipulate biological processes. Research topics such as the origin of life, the nature of diseases, and the development of individual organisms required chemical knowledge to explain the mechanisms at the molecular level. 2. [The chemical nature of physiological phenomena: For the study of the chemical nature of physiological phenomena at the molecular level, chemical methods and scales play a key role.] For example, the study of the internal structure of cells relied on physics methods such as X-ray refraction and electron microscope. The advancement of these physical and chemical technologies allowed humans to understand life at the molecular level, thus helping to understand the chemical nature behind physiological phenomena. 3. ** Biochemical control **: The theoretical basis of biochemical control is the interweaving of chemistry and biology. Chemistry could be used to analyze the composition and physical properties of bio-related materials to facilitate the identification and control of pathogenic bacteria and pests. In biochemical control technology, chemical technology produced a variety of efficient and environmental protection chemicals (such as weeding agents, pesticides, sealants, etc.) that could be used to control specific harmful organisms, preventing the occurrence of various diseases, borers, fallen leaves, etc. This involved biological knowledge such as the impact on biological growth and metabolism. 4. Chemistry in biology: Chemistry is the foundation of the concepts and methods of biochemistry and molecular medicine. Some topics in the biology course, such as cell biology, will also involve chemistry knowledge because the composition and metabolism of cells are inseparable from chemical substances and chemical reactions. For example, when studying processes such as cell breathing and photosynthesis, chemistry knowledge was needed to understand the transformation of substances. 5. ** Knowledge fusion in the cross-disciplinary field **: In the cross-disciplinary field of chemical biology, the research of life sciences was driven by the scientists. The research techniques and intervention methods of chemical ideas could be used to solve problems that were difficult to solve with traditional biological methods and techniques, reflecting the application of chemical knowledge in biological research. For example, in the study of the synthesis of biological molecules, the relationship between structure and function, chemical theories and methods (such as organic synthesis, analytical chemistry methods, etc.) played an important role. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following methods can be used to determine whether there are microorganisms in canned food: 1. ** Sealing test and expansion test **: Place the inspection samples of meat, poultry, and aquatic products at 37 ° C +/-2 ° C for seven days; place the canned fruits and vegetables at 20 - 25 ° C for seven days, and observe whether the bottom and cover of the can expand. In addition, a sealing test (5 minutes in water above 85 ° C) can be carried out to determine the tightness of the can. If the seal is not good, it may cause microorganisms to enter. 2. ** Enrichment culture and observation **: Take about 1g or 1ml of the middle part of the sample with sterile forceps or a straw, and then incubate it into two tubes of buffer glucose broth and two tubes of meat culture medium respectively. Then take one tube of each as a blank control. The tubes of the Blister Meat Medium were soaked in boiling water for 10 minutes to kill non-spore bacteria before being incubated, and then cultured at 37 ° C for 5 - 7 days. After two days, observe and record every day to see if there is any mixed corrosion or membrane in the buffer glucose broth; if there is any mixed corrosion, gas production, red or black blisters in the meat culture medium, smear, stain, and microscopic examination should be carried out. 3. ** Pathogenic bacteria test **: According to the observation results, if there is bacteria growth in the buffer glucose broth medium, and the staining microscopic examination shows that it is a gram positive cocci, it can be suspected to be salmonella, shigella, etc., and then determine whether there is a specific pathogenic bacteria. These inspection procedures went through multiple steps, from preliminary judgment to precise microscopic testing to determine the presence of microorganisms in canned food. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
