How to learn high school biochemistry by yourself
Here are some high school biochemistry self-study methods: ** 1. Self-study method for high school biology ** 1. ** Building a knowledge framework ** - Using the textbook table of contents and the sub-titles of the programs, he had a macro grasp of the contents of the textbook. He could try to summarize the textbook's writing ideas and clarify the logical relationship between the knowledge points after reading the textbook. This way, he could quickly locate the textbook basis corresponding to the test points when doing the questions. - Use appropriate memorization methods to strengthen the knowledge framework. For example, the simplified memorization method could simplify the memory of DNA molecular structure into a regular expression by summarizing the key points, and the outline memorization method could extract keywords such as the core process of higher animal metabolism as a knowledge outline to help the overall memory. 2. ** Learning Knowledge ** - He followed the principle of "memorizing first, understanding later". Because the cells, tissues, and other elements of thought in biology were relatively unfamiliar, one needed to remember the basic knowledge points such as terms and terminologies before understanding the logical laws. - Pay attention to the internal connection of knowledge, and be cautious. For the knowledge that appeared in different chapters, such as the discussion of DNA in the "Introduction","Compound that makes up organisms", and "Inheritance and variation of organisms", they had to link them together and think about them. For knowledge that was parallel to the structure and function of the organelle, they had to compare and learn. - For important knowledge, think about the "six W's"(Who, What, How, When, Where, Why) when you read to understand the content of the knowledge. 3. ** Supporting learning resources ** - He could watch some high-quality biology learning videos. For example, Infinite Small Light's popular science was suitable for the development of biological knowledge in primary school and the cultivation of interest; Anna Biology gave a detailed explanation of the knowledge chapters of junior high school biology, and also listed the key difficulties and test points; Li Lin Biology explained the high school biology questions in detail, which was suitable for high school students who did not have a solid grasp of biological knowledge in school. Through his video, they could follow the questions, including the basic 1000 questions, the simulation set of papers, the real questions over the years, etc. ** 2. Self-study method of high school chemistry ** 1. ** Building a knowledge framework ** - Chemistry also needed to sort out the framework of the textbook and make clear the connections between the various chapters, such as the connection between the knowledge of elemental compounds and chemical principles. 2. ** Learning Knowledge ** - The basic concepts and principles of chemistry were emphasized. Basic concepts such as atomic structure and chemical bonds were the cornerstone of learning chemistry. They needed to be understood in depth. - For key content such as chemical equations, one had to understand the nature of the reaction, including the changes in the reagents and products, as well as the effects of the reaction conditions. - Focus on learning experimental knowledge. Chemistry was a subject based on experiments. Understanding experimental principles, experimental phenomena, and experimental conclusions would help one master chemistry knowledge. 3. ** Supporting learning resources ** - In elementary school, one could watch the video of the real Phoenix Dance in the Nine Heavens and understand the role of chemistry in life through simple experiments. In junior high school, he watched Sister Qian Yue's chemistry class. He could sort out the high-frequency test points, the necessary test points, and the difficult points. There were also practice questions. In high school, he could refer to the Chemistry Superman's review and follow his train of thought to solve the questions and learn the answering skills of the question type. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

How to learn high school biochemistry knowledge with zero foundation
The following is a way to learn high school chemistry with zero foundation: 1. ** Build a solid foundation ** - ** Previewing the new lesson **: Previewing the content of the new lesson in advance before class. There is no need for in-depth understanding. As long as you have a general understanding of the knowledge points, it will help you catch up with the pace of the class and grasp the key points faster. - ** Pay attention to the classroom **: The classroom is the key to learning chemistry. In class, you must focus on following the teacher's train of thought and take notes on the key points, difficulties, and error-prone points emphasized by the teacher for review after class. - " Clear basic concepts ": Chemistry focuses on basic concepts. Concepts such as elements, molecules, atoms, and valency must be clear because subsequent learning is based on these concepts. - ** Do more exercises **: Test your mastery of the knowledge points by doing questions and find out the shortcomings. Students with poor foundations should formulate learning strategies according to their own situation. 2. ** Master learning methods to improve efficiency ** - [** Inductive summary **: Chemistry knowledge points are numerous and messy. You can summarize the same type of elements and reactions. This will help you remember and deeply understand the connections between knowledge points.] - ** Use diagrams and models **: For abstract concepts and complex structures, use diagrams and models such as molecular structure models and the periodic table of elements to assist in understanding. - ** Associate Memory **: For elements symbols, chemical formulas, and other contents that need to be memorized, you can use the association memory method. For example, imagine the elemental symbol H of hydrogen as a person wearing a hat. - ** Ask for help **: Don't be afraid or shy when you encounter a problem. Ask your teacher or classmates for help. A little hint may make you feel enlightened. - ** Maintain interest **: Associate chemistry knowledge with daily life, such as observing chemical reactions in the kitchen, understanding the chemical components in cosmetics, etc., and feel the charm of chemistry. - ** Remember experimental phenomena and equations **: High school students have limited time and conditions. You must remember the experimental phenomena in the books. Many experimental phenomena can be categorized to find similarities and differences. Complex chemistry questions often derive reactions and substances based on phenomena, so you must remember chemical reaction phenomena. For chemical reaction equations, remember some basic reactions after understanding the nature of the reaction. The rest can be derived temporarily. However, the special reactions in the book need to be memorized separately. It is enough to understand and apply the reactions encountered when doing the questions. - ** Pay attention to details **: Chemistry questions have many test points and knowledge points. When reviewing, you need to start with every small knowledge point. You can't have a fluke mentality. The following are the methods to learn high school biology knowledge with zero foundation: 1. ** Key points of mastering basic knowledge **: Use the method of " memorizing first, then understanding " because biological knowledge also needs to be memorized on the basis of understanding. Moreover, the thinking elements of high school biology, such as cells, tissues, organic matter, and mineral matter, are relatively unfamiliar to students. You need to remember these terms and terms before you can grasp their logical laws. 2. [Understand the internal relationship of knowledge: After memorizing the basic terms, terms, and concepts, focus on learning the laws of biology. Focus on understanding the vertical and horizontal connections between the various structures of organisms and groups.] 3. ** Deep understanding of key knowledge **: You must have a deep understanding of key and difficult knowledge. When you study, you must achieve the "six W's". <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Can I choose biochemistry and geography in high school?
Sure. Under the new college entrance examination model, biology, chemistry, and geography were all subjects that could be chosen. This combination had its own characteristics. For example, biology and chemistry were less difficult to learn than physics, and many contents needed to be memorized and summarized. Geography had both literary and artistic thinking, and the relationship between disciplines was relatively close. In terms of specialty coverage, this combination had a specialty coverage rate of 87.4%, which was considered low among the 20 combinations of "3+3." The available majors included engineering majors that did not have high requirements for physics, such as materials science, food science and engineering, environmental science and engineering, chemical and pharmaceutical science, geological science, mining science, water conservancy science, textile science, biology, etc. Most of the major science majors such as chemistry, geographical science, biological science, marine science, geological science, psychology, and some medical majors. However, there were also limited majors. Most engineering majors had restrictions, such as electronic information, computer science, weapons, aerospace, nuclear engineering, and instruments. A small number of science majors, such as mathematics and physics, also had restrictions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Analysis of the questions and answers of biochemistry for high school students
The following are some high school questions and answers: ** 1. Biological Part ** 1. [Title: The largest ecosystem on Earth is ()] - [Option: A.] Forest ecosystem B. Ocean ecosystem C. farmland ecosystem. urban ecosystem - [Answer: B] - ** Analysis **: The marine ecosystem covers about 70% of the Earth's surface area. It contains a rich variety of biological species, huge amounts of organisms, and a diverse ecological environment. Compared to other ecological systems, its scale and complexity make it the largest ecosystem on Earth. 2. ** Question **: Which of the following is not a component of biological richness?（ ） - [Option: A.] Genetic DiversityB. Species DiversityC. ecosystem diversityD. environmental diversity - [Answer: D] - ** Analysis **: Biological variation includes genetic variation (the variation of genes within the same species), species variation (the richness of different species), and ecosystem variation (such as forests, grasslands, and grasslands). However, environmental variety was not a part of biological variety. The environment was the external condition for the survival of living creatures, and biological variety was the variety related to living creatures themselves. 3. [Question: Which of the following organisms does not produce food through photosynthesis?]（ ） - [Option: A.] Green algae B. Cyanogen C. Fungus D. mangrove - [Answer: C] - [Analysis: Both green algae and blue bacteria contain photosynthesizing substances that can photosynthesize to produce food.] Mangroves were plants that could also photosynthesize. Fungi, on the other hand, were heterotrophs. They could not produce food through photosynthesis, but obtained nutrients by decomposing organic matter or parasitizing. ** 2. Geography ** 1. [Question: Which of the following phenomena is not affected by climate change?]（ ） - [Option: A.] Glaciers Melting B. Sea level rise C. Species extinction frequent earthquakes - [Answer: D] - [Analysis: climate change will lead to an increase in temperature, causing glaciers to melt. Melting glaciers will cause sea levels to rise.] At the same time, climate change would change the living environment of living creatures and could lead to the extinction of species. Earthquakes were caused by the Earth's internal structural movements and had nothing to do with climate change. 2. [Title (Human Geography): What are the main factors that affect the spatial structure of a city?] - ** Answer **: economic factors (rent level, ability to pay rent, etc.), social factors (income, popularity, race or religion, etc.), historical factors (early land use methods, historical and cultural heritage, etc.). - ** Analysis **: The economic factor is the most important factor. The rent level in different parts of the city is different, and the rental ability of commercial, industrial, residential and other land is also different, which determines their distribution in the city. In terms of social factors, high-income people might be more inclined to live in areas with better environments, and some ethnic minorities or religious groups might have a tendency to live together. Historical factors such as the layout of buildings and functional divisions in some Laocheng District may have been left over from history, which also affected the current urban spatial structure. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
