The following is an explanation of the concepts related to cell biology: ** 1. Basic Concepts of Cell ** 1. ** Understanding that cells are the basic unit of life activities ** - From a structural point of view, all organisms were made up of cells, and cells were the foundation for constructing organisms. - The cells had an independent and orderly self-controlled metabolism system. They were the executors of metabolism and function. The cell was also the foundation for the growth and development of an organism. It was also the basic unit of inheritance and had genetic omnipotency. Without cells, there would be no complete life. The cells themselves were a multi-layered, non-linear, and complex structural system. They were also a complex combination of substance (structure), energy, and information processes. They had a high degree of order, self-assembly, and self-organization. 2. ** The reason for the existence of the smallest and simplest form of cells ** - It could grow on a medium and had a typical cell membrane. - Its genetic information was carried by a circular double-stranded DNA. The messenger acid could combine with the Ribosome to form a polysome to guide the synthesis of the protein. It split into two and multiplied. Its size was only one-tenth of that of bacteria, and it could also parasitize and reproduce in the cell. 3. ** The understanding of viruses as non-cellular life forms and the difference and relationship between viruses and cells ** - A virus was composed of a core of a single DNA or R A and a shell of a protein. It was the smallest and simplest organism. There were also special forms such as virus-like viruses that were composed only of infectious R A and prions that were composed only of infectious protein. Although viruses had the basic characteristics of replication and inheritance, they lacked the structure of cells and were incomplete life forms. Its main life activities could only be displayed inside the cells. It replicated and proliferated inside the host cells. It did not have an independent metabolism and energy conversion system. It had to rely on the host cells 'structure, raw materials, energy, and digestive system to proliferate. It was a complete parasite. - Compared to cells, viruses were very small and had a very simple structure. Their genetic carriers were diverse and completely parasitic. They proliferated by replicating and assembling. ** 2. Concepts related to cell classification ** 1. ** Evolutionary similarities and differences between prokaryonic cells, archaeokaryotic cells, and eukaryonic cells **(The reference materials did not provide a complete analysis, from the perspective of general knowledge) - The similarities were that they all had genetic material, which was related to the basic functions of life, such as the ability to synthesize certain substances. - The difference: - Procaryotes did not have a nucleus covered by a nuclear membrane. Their DNA was exposed, and they had the characteristics of space-time continuity in DNA replication, replication, and translation. - Eukaryotic cells had a nucleus that was covered by a nuclear membrane, and its expression and regulation were much more complicated. It could be regulated at various levels, such as pre-transcribed level, transcribed level, post-transcribed level, translated level, and post-translated level. - Archaeus cells had unique properties in some aspects. In terms of evolutionary relationship, they were in a special position between procaryotic cells and eukaryotic cells. For example, they had some characteristics different from procaryotic cells in terms of gene replication and translation. ** 3. Concepts related to cell structure and function ** 1. ** Concepts related to the composition of cells ** - The most basic biological small molecules that make up cells are the nuclei, the acids, the fatty acid, and the sugar. They form important biological molecules such as the nuclei, the protein, the fat, and the glycan. 2. ** Concepts related to cell sub-discipline (Experimental Biology)** - The main branches of cell science that were formed by the combination of cell science and other biological sciences were cell genetics, cell biology, and cell chemistry. 3. ** Concepts related to cell membrane structure ** - Phospholiptides on the biological membrane mainly include Phosphatidylcholin (Phosphatidyl Choline), Phosphatidyl Serine, Phosphatidylinositol, Phosphatidylethanolamin, and Sphingomyelin. The membrane protein could be divided into membrane intrinsic protein (integral membrane protein) and membrane peripheral protein (membrane outer protein). The basic characteristics of biological membranes were mobility and unsymmetrical. The main ways of binding between intrinsic protein and membrane were the interaction of water affinity, ion bond, and the interaction of the two bonds. 4. ** Concepts related to cell connection ** - Cell connections could be divided into closed connections, anchored connections, and communication connections. The main ways of anchor connection were desmosome, hemidesmosome, and the adhension zone and focal adhension. The desmosome was connected to the intermediate fibers in the skeletal system, while the adhension zone was connected to the microfibers (actins). The main ways of communication were gap junction, plasmodesmata, and chemical bond. 5. ** Concepts related to the extra-cellular matrix ** - The basic components of the matrix were mainly composed of protein, elastins, glycan, laminins, fibronectins, etc. The main components of plant cell walls were Celluloses, Hemicelluloses, Flucoids, Expansins, and Proglycans. 6. ** Concepts related to cell surface specialized structures ** - The specialized structures formed on the surface of the cell included membrane skeleton, microvils, flagella, cilia, and deformed feet. 7. ** Concepts related to the transport of substances across membranes ** - The main pathways of material transport across the membrane were passive transport, active transport, as well as the effects of engulfment and exomyosis. Passive transport could be divided into simple and assisted diffusing. The latter required specific membrane transport protein (carrier protein and channel protein) to complete the transport of substances across the membrane. According to the energy source, active transport could be divided into ATP-directly powered transport, ATP-indirectly powered transport, and optical driven active transport. Co-transport belonged to the active transport type. According to the relationship between the direction of material transport and the direction of ion transfer along the electrochemistry, it could be divided into co-transport (co-transport) and reverse transport. For example, in the sodium-potassium pump, every atom of ATP-consumed could transport 3 Na ions and 2 K ions. The sodium-potassium pump and the calcium pump were both multi-spanning membrane protein with ATP-ase activity. In eukaryotic cells, there were three types of photon pump: P-type photon pump, V-type photon pump, and H + -ATPases. The transport of large molecules across the membrane was completed by transcytosis and exomyosis. According to the size of the vesicle and the substances that were swallowed, transcytosis could be divided into transcytosis and engulfment. ** 4. Concepts related to cell observation technology ** 1. ** Microscope resolution concept ** - The resolution referred to the smallest distance between two particles that the microscope could distinguish. 2. ** Concepts related to electron microscope ** - The electron microscope was mainly divided into two types: transmission electron microscope and scanning electron microscope. The commonly used electron microscope techniques in biology included ultra-thin section technique, negative staining technique, freeze-engraving technique, and so on. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The oral chemotherapy drugs for tongue cancer may have the following side effects: 1. Blood system reactions: For example, bone marrow suppression. During the course of medication, there may be abnormalities in laboratory indicators such as decreased white blood cells, decreased Blood Platelet, and leukemia. 2. Digestive tract reactions, including loss of appetite, nausea, vomiting, diarrhea, abdominal pain, abdominal distension, etc. 3. Mouth: The tongue may turn white, which may be caused by the side effects of chemotherapy drugs that cause damage to the mucus cells in the mouth and tongue, making the mouth and tongue more sensitive and fragile. It may also be due to the suppression of the immune system after chemotherapy, which makes it easy for oral candida infection to occur, causing the surface of the tongue to be covered with a white membrane. 4. There may be numbness in the hands and feet, which may be caused by adverse effects of chemotherapy drugs on the nervous system, or radiation therapy affecting the nerve tissues of the oral cavity and throat, which in turn affects the nerves of the arms and legs. It may also be due to a lack of B vitamins and other nutrients due to loss of appetite during chemotherapy. It may also be caused by other factors such as diabetes, infection, and immune diseases interacting with chemotherapy. 5. After chemotherapy, there might be a chance of a nasal cavity or a nasal cavity. Ulcers could appear in the entire digestive tract, including the oral cavity and anus. Mouth ulcers usually appeared four to six days after chemotherapy, and they could also trigger a fungus or mold infection. 6. It could cause damage to liver cells. In severe cases, it could cause liver function to decrease, and it could also cause coagulation disorder. 7. Hair loss may occur, usually starting two to three weeks after the first dose of chemotherapy. Hair will slowly grow out six to eight weeks after stopping the chemotherapy drug. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following are some ways to write a reflection on language teaching after third grade: ** 1. Achievement of teaching objectives ** 1. ** Knowledge and Skills ** - Review whether the students have mastered the necessary knowledge of words, such as the pronunciation, writing, meaning understanding of new words, etc. For example, when teaching some texts that describe natural scenery, check the students 'understanding and ability to use the adjectives and verb that describe the scenery. If you find that students have a high rate of writing errors in a new word during class practice or homework, reflect on whether the writing guidance of the new word is not detailed enough during the teaching process, such as the explanation of stroke order and glyph structure. - He would then consider whether he had achieved the goal of understanding the content of the text. For example, when teaching narrative texts, whether the students could accurately summarize the cause, process, and result of the event; for explanatory texts, whether the students understood the characteristics of the object of explanation, and so on. If the student has difficulty in generalizing the content of the article, reflect on whether the student did not grasp the key sentences or the structure of the article was not clear enough. - Checking the development of reading and writing skills. In the teaching of reading, whether or not the students 'reading skills were cultivated, such as the grasp of intonation and rhythm, as well as reading comprehension ability, such as the understanding of the main idea of the article and the author's feelings. In terms of writing, whether it provides students with certain writing ideas or methods of guidance, for example, through text learning, let students imitate a certain writing structure to practice writing. If the student's practice is not good, think about whether it is because the teaching is not enough or the writing requirements are not clearly explained. 2. ** Method and process ** - Think about the effectiveness of teaching methods. For example, whether the use of multimedia-assisted teaching could really help students understand abstract knowledge. For example, when explaining ancient poems, whether the images displayed by the multi-media could help the students better understand the artistic conception of the poems. If the students 'understanding of the artistic conception was still vague, it might be that the images did not match the content of the poems well enough, or the teachers did not guide the students to combine the images with the words of the poems in an appropriate way. - Reflect on the use of learning methods such as autonomous learning and cooperative learning. In the process of group cooperative learning, whether every student can actively participate and whether the expected cooperation effect is achieved, such as discussing problems together and inspiring each other. If it was found that there was a phenomenon of individual students "free-riding" in the group cooperation, they would consider whether the division of labor in the group was unreasonable or there was a lack of effective supervision and evaluation mechanism. - Investigate whether the guidance in the learning process is appropriate. For example, when guiding students to analyze the text, whether the questions raised were enlightening and whether they could guide students to think deeply. If the students were indifferent to the teacher's questions, it might be because the questions were too simple or complicated, or the way the questions were asked was not attractive enough. 3. ** Emotions, attitudes and values ** - He wondered if he had aroused the students 'interest in learning Chinese. For example, when teaching literary texts, whether to let the students feel the charm of the language through vivid explanations and interesting expansion of the content. If the students showed a lack of enthusiasm for language learning in class, they would reflect on whether the teaching content was too boring or the teaching method lacked innovation. - Consider whether the students have cultivated positive emotional attitudes, such as love for nature, respect for honesty, etc. After teaching a text describing the beauty of nature, whether the students showed more love for nature could be judged from the students 'classroom speeches, after-class essays, and other aspects. If the expected effect was not achieved, the teacher should reflect on whether the teaching process lacked emotional penetration or emotional guidance was not deep enough. - Check whether the students have been guided to establish correct values. For example, when learning some texts about the character's moral character, whether the students understood and agreed with the values embodied by the characters in the text, if the students had misunderstandings about the values in the text, they should reflect on whether the teaching lacked in-depth analysis of the meaning of values or lacked connection with real life. ** II. Strengths and weaknesses in the teaching process ** 1. ** Strengths ** - Review successful teaching processes or strategies. For example, in a certain teaching session, students 'participation was very high. For example, in the classroom discussion session, students actively spoke and exchanged their views with each other. This might be because the questions were open and interesting, or the teacher created a relaxed and democratic classroom atmosphere. - Think about the unique creativity or highlights in teaching. For example, role-playing could be used to interpret the plot of the text. This method could allow students to understand the characters and the content of the text more deeply. If the role-playing effect was good, it would be a teaching highlight worth concluding. It could be used and perfected in future teaching. - It summarized the teacher's outstanding performance in the teaching process, such as clear and concise language, vivid explanation, and the ability to simplify complex knowledge. If the teacher's language was infectious, it could attract the students 'attention and stimulate their interest in learning. This was an important factor in improving the teaching effect and needed to be maintained in future teaching. 2. ** Not enough ** - Find out the problems in the teaching process. For example, if the teaching rhythm was not controlled properly, a certain segment would take too long, resulting in the subsequent teaching content being rushed to the end. For example, when he explained the key passages of the text, he analyzed every sentence in too much detail, making the time for the subsequent classroom exercises and summary sessions tense, affecting the integrity of the teaching. - Reflect on classroom management issues. If there were disciplinary problems in the classroom that affected the teaching effect, he would think about whether the classroom rules were not clear enough, or the discipline management of the students was not strict enough or there was a lack of effective management methods. - Thinking about the shortage of teaching resources. For example, although the multi-media coursewares were exquisitely made, some of the content was not related to the teaching focus and distracted the students 'attention; or they did not make full use of the illustrations and after-school exercises in the teaching materials to assist in teaching. If these resources were not used effectively, it might affect the teaching effect. ** 3. Enhancement measures and future teaching prospects ** 1. ** Modification measures ** - According to the achievement of teaching objectives and the shortcomings in the teaching process, specific improvement measures were proposed. If there are problems in word teaching, you can increase the time and form of word practice, such as holding a word competition, making word cards, etc. As for the cultivation of reading ability, if students were found to have difficulties in reading comprehension, they could increase the amount of reading practice and give more guidance on reading methods, such as teaching students how to take reading notes, how to make text annotations, etc. - In view of the shortcomings of the teaching method, adjust the teaching method. If the results of group cooperation learning were not good, they could re-design the group tasks, clarify the division of labor among the group members, and establish an effective group evaluation mechanism, such as setting up a group cooperation results display segment, rewarding the outstanding group, and encouraging students to actively participate in group cooperation. - improve classroom management. If there were problems with classroom discipline, they could formulate clear classroom rules and emphasize them at the beginning of the school term or at the beginning of each class. At the same time, they could adopt a variety of management methods, such as eye reminders and approaching students who violated the rules, so as to maintain classroom discipline without affecting the teaching process. 2. ** Future teaching prospects ** - Thinking about how to further improve the quality of teaching in the future. For example, they could expand and deepen the teaching content, combine textbook knowledge with extra-cursory knowledge, and broaden the students 'knowledge. For example, when teaching ancient poetry, one could introduce more works of the same poet or other poems related to the theme of the poem for comparison. - To explore how to better meet the individual learning needs of students. Every student's learning ability and learning style were different. They could think about how to adjust teaching strategies according to the differences of students. For example, they could adopt a tiered teaching method to provide students with different difficulty learning tasks or provide more learning options to allow students to learn according to their own interests and abilities. - Looking forward to how to constantly create new ideas in teaching. With the continuous updating of educational concepts and the development of educational technology, it was possible to think about how to integrate new teaching concepts and technologies into Chinese teaching, such as using virtual reality technology to let students experience the scenes in the text, or using project-based learning methods to carry out Chinese teaching activities. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

In jadeite," fluorescent reaction " had a specific meaning. In the early days of the counterfeit goods on the market, due to the limited technology, the pickled jade was mostly filled with epoxide-based resin. This organic resin would stimulate visible light under a purple light, which was the fluorescent reaction. The jade that was dipped in wax would show blue-white fluorescence under the fluorescent light, and the jade that was injected with glue after artificial strong acid rinsing would show blue-white or green-white fluorescence under the fluorescent light. Generally speaking, jadeite with fluorescent reaction was often treated with chemicals and not natural A-grade jade. However, there were special circumstances. For example, natural jadeite used polishing powder during the polishing step. When the polishing powder remained on the surface of the jadeite, it might also cause a fluorescent reaction. Moreover, fakes were also being upgraded. Some of the new B + C fakes were filled with non-fluorescent substances and stains. They did not react under the purple light and were difficult to distinguish from natural jade. Therefore, the fluorescent reaction could not be used as the only basis to determine the authenticity of jade. The novel "Ledge" is equally exciting. Everyone is welcome to click and read it!
