In Jinan's qualification examination, generally speaking, 60 points was considered a pass. The biology subject also followed this standard. However, in the 2020 Jinan Biology General Examination (included in the results of the middle school entrance examination), the passing score would be determined by reference to the number of people and the score of the current examination. If 93% of the people in the current examination scored more than 50 points, then 59 points would pass. However, under normal circumstances, it was more likely to strive to pass the examination with more than 60 points. Read more exciting novels for free

The compulsory knowledge points for biology in Grade Eight included, but were not limited to, the following: ** 1. Creature classification ** 1. The smaller the taxon, the more common characteristics the organisms contained, and the closer the kinship. The larger the taxon, the fewer common characteristics the organisms contained, and the farther the kinship. 2. The smaller the taxon, the fewer species it contained. Conversely, the larger the taxon, the more species it contained. 3. The same size principle meant that if two or more organisms belonged to a smaller taxon, they must belong to a larger taxon. 4. Species were the basic unit of biological classification. Species did not belong to the biological classification unit. Species were different forms of expression within the same species. For example, laying chickens and broiler chickens were different breeds of the same species. 5. The biological hierarchy system was composed of the order of each classification level according to its level and subordinate relationship. Based on this, the position of various organisms in different taxa could be found, such as dogs (dogs) belonging to animals, species belonging to dogs, canine, carnivorous, mammalia, vertebrae in the chordate, and animal kingdom. ** 2. Evidence of biological evolution ** 1. Creatures on Earth did not appear at the same time. Some continued to exist until now, while some were extinct. Modern creatures had gradually evolved over a long period of time. 2. Fossil was one of the evidence for the study of biological evolution, but it could also be studied by comparing the individual structure of different species. For example, by comparing the organs of some species, it was found that there was an evolutionary trend. Homological organs reflected the kinship between organisms. Homological organs had the same origin, and the differences in appearance were caused by adapting to different environments and performing different functions during evolution. 3. The study of molecular biology had a special significance for biological evolution. By determining the structure of protein and DNA, one could accurately determine the kinship between organisms. The closer the kinship, the smaller the difference between the protein or DNA molecules. Although the process of biological evolution was long and could not be directly observed or replicated through experiments, the laws of evolution could be summarized through comparison, induction, and reasoning. ** 3. Heredity and environment ** 1. The relationship between the gene type and the gene type - Generally, environmental conditions did not change the gene type, but the expression type was easily affected by environmental conditions. For example, the leaves of the water buttercup would be flat when it reached the surface of the water, but the leaves would split into threads when it was submerged in water. The white rabbit of the Himalayas would have different fur colors under different temperatures, but the ordinary white rabbit would not be affected by this temperature. 2. variation - Mutation was a common phenomenon in the biological world. - Inheritable mutations are caused by changes in genetic material (genetic composition). Trait mutations can be repeated in future generations. This variation will affect the metabolism of the organism and cause trait mutations. - Non-heritable mutations did not involve changes in genetic material. They were only caused by external environmental conditions. Trait mutations could not be passed on to future generations, such as plant height and bean size differences of the same pea variety planted in different plots, as well as the blackening of Caucasians due to exposure to the sun (the gene type did not change, but the expression changed). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The following is a summary of some high school biology knowledge points: 1. The relationship between chemical elements and organisms: organisms contain a variety of chemical elements. These elements have different functions and effects in the body, such as forming compounds and participating in physiological processes. 2. The list of compounds in the cell: There are many kinds of compounds in the cell, such as sugar, fat, protein, and nuclear acid. Each of them has different structures and functions. For example, sugar is the main energy material, fat can store energy, and so on. 3. Nucleic acid was divided into DNA and DNA, and its basic units were respectively, DNA and DNA. 4. Identification of reducing sugar, fat, protein, and DNA in biological tissues: Use specific reagents for identification. For example, Fehling's reagent can identify reducing sugar and produce brick-red precipitations; Sultan III dye solution can identify fat and produce orange color, etc. 5. The characteristic of the membrane was that it was selectively pervious, allowing certain substances to pass through while preventing other substances from passing through. 6. The cell membrane's substance exchange function: The cell membrane can carry out substance exchange through free dispersion, assisted dispersion, active transportation, and other methods. 7. The similarities between mitochondria and plastids were that they both had a double-layered membrane structure, were related to energy conversion, and contained a small amount of DNA. 8. The comparison of eukaryote organelle: Different organelle had differences in structure and function. For example, the ER was the synthesis, processing, and transportation channel of protein and other molecular substances; the Golgi apparatus mainly processed, classified, and packaged the protein from the ER. 9. During mitosis, the changes of nuclear DNA, the nuclei of the nuclei, and the nuclei of the nuclei were as follows: during the interphase, DNA replication and the synthesis of related protein were carried out, and the DNA content was doubled; during the prophase of mitosis, the nuclei of the nuclei appeared, and at the anaphase, the nuclei of the nuclei split, and the sister Chromatids separated. 10. The source of ATP-in the body: It is mainly produced by cell breathing (both oxygen and oxygen free breathing) and photosynthesis. 11. [The destination of the ATP-binding in the body: It is used for various life activities of cells, such as muscle contraction and material synthesis.] 12. The comparison between light reaction and dark reaction in photosynthesis: the light reaction occurs on the thylakoid membrane of the plastids, producing oxygen, bound bound 13. The relationship between light energy utilization rate and photosynthesis efficiency: Light energy utilization rate refers to the ratio of the energy contained in the organic matter accumulated by the plant's photosynthesis to the sunlight energy that shines on the ground; photosynthesis efficiency refers to the ratio of the energy contained in the organic matter produced by green plants through photosynthesis to the light energy absorbed during photosynthesis. 14. The relationship between the external factors that affect photosynthesis and the improvement of light energy utilization: The external factors include light intensity, temperature, carbon dioxide concentration, etc., and appropriately increasing the value of these factors can improve the light energy utilization. 15. The metabolism of the three major nutrients in humans and animals: sugar, fat, and protein can be synthesized and decomposed in the body, and they can be converted to each other. 16. The comparison between the two types of breathing: Aerobic breathing produces a large amount of energy and requires oxygen to participate. The reaction site is mainly the mitochondria. The anoxia-less breathing produces a small amount of energy and does not require oxygen. The reaction site is the cellular matrix. In addition, there were also knowledge points about cell structure and function, gene expression, genetic laws, biological evolution, ecological systems, etc., such as cell membrane system, gene translation and translation process, Mendel's law of inheritance, modern biological evolution theory, etc.(Genetic frequency changes, isolation and speciation, etc.), the components of the ecosystem (producers, consumers, disposers, non-biological substances and energy), energy flow (one-way flow, step-by-step reduction), material circulation, and many other topics. These knowledge points were all important parts of high school biology learning, but due to space constraints, it was difficult to list all 300. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The junior high school biology exam covered many aspects. In terms of cell structure, the cell wall, plastids, and vesicles that were unique to plant cells were one of the test points. At the same time, the relationship between the object image magnification and the magnifying power of the eyepieces and objective lenses could also be examined. In terms of biological genetics, the main genetic material, DNA, and its existence in the nucleus of the cell were the key points, including the content related to human gender inheritance. In terms of biological composition, the animal body from cells to tissues, organs, systems, and then to the hierarchy of the animal body. Among them, the four major tissues of humans and animals, such as human and animal tissues, muscle tissues, Connective tissues, and nervous tissues, were the test points. The relevant knowledge of plant tissues such as protective tissues, basic tissues, conducting tissues, mechanical tissues, and meristematic tissues might also be involved. In the part of the ecosystem, its components included non-biological components such as sunlight, air, water, and soil, as well as biological components such as producers (green plants), consumers (humans and animals), and resolvers (bacteria and fungi). Knowledge related to the establishment of nature reserves and the establishment of zoological and botanical gardens may also appear. In terms of plant groups, the order from algae to mosses, ferns, gymnosperm, and flowering plants from low to high, such as the highest flowering plant.(The meaning of "quilt" refers to the fruit peel), coal formed by ancient ferns, the contribution of algae to atmospheric oxygen content, the ability of iodine-containing seaweed and seaweed to prevent and treat local goiter, the growth environment of mosses and ferns, the monitoring of air pollution by mosses, and the eutrophy of water bodies leading to marine red tides and freshwater blooms may be tested. Vertebrate animals, from fish to amphibians, reptiles, birds, and mammals, from low to high, were the test points. For example, the four major domestic fishes, mussels were mollusks, frogs were amphibians, reptiles were reptiles, pigeons were birds, insects were insects, earthworms were annelids, and so on. Biological classification was based on the characteristics of the biological structure and the seven levels of the classification system (Realm, Phylum, Class, Order, Family, Genus, and Species). In terms of human nutrition, there are six types of nutrients necessary for the human body. For example, the most abundant substance in the human body is water, followed by protein, starch that turns blue in contact with iodination solution, vitamins C that fades in the presence of potassium Permanganate solution, protein that freezes in high temperatures, and fat that leaves oil spots on paper.(Carboids are the main energy-supplying substances, fats are the main energy-storing substances, and protein is an essential component for the composition and repair of cells), as well as the small intestine, the main absorption site of nutrients (the small intestine is compatible with digestive function), scurvy caused by lack of vitamins C, rickets caused by lack of vitamins D or calcium deficiency (children), and bone loss (adults). The difference between the photosynthesis of green plants and the application of the two, such as the main source of oxygen in the air from the photosynthesis of green plants, was also a test point for junior high school biology. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following are some of the main points of the analysis of the junior high school biology final test: ##1. Achievement 1. ** Overall results ** - In some areas, the overall results of the biology final exams were not ideal. For example, there were 420 students in a certain district, with an average score of 52.2 points. 87 students scored above 80 points, and 179 students passed. This indicated that there might be areas for improvement in teaching. 2. ** The problems reflected in the results ** - ** Basic knowledge is not well grasped **: For example, some of the questions in the multiple-choice questions are wrong because they are not familiar with the knowledge points. For example, some questions are not ideal because the seventh grade students have just come into contact with biology and their knowledge of botany is mainly in this semester. - ** Poor standard of answers **: In the non-multiple choice questions, students do not answer the questions according to the standard. For example, they were required to fill in the letter code but wrote the structure name, and there were mistakes such as "hereditary" being written as "transmission" and "transfer". There were also problems such as language errors and inaccurate answers. - ** Not careful in reading questions **: It is easy to misread key information in the questions, such as "humidity" as "temperature", etc. In some questions, it is possible to lose points due to the problem of reading questions. ##2. Test Paper 1. ** Proposition characteristics ** - ** Closely adhere to the outline and teaching materials **: The difficulty of the test paper is usually moderate. It is closely related to the requirements of the middle school examination outline and teaching materials. The distribution of knowledge points in each chapter is reasonable. It can test basic knowledge points and flexibly. It requires theory to be combined with practice. - ** Reflects a variety of abilities **: It is open and is conducive to the development of students 'subjective thinking ability. It can guide students to pay attention to social hot topics and practical life. It tests students' ability to analyze and solve problems. It also includes certain knowledge transfer ability and comprehensive ability. For example, some of the questions were related to production and daily life, as well as reflecting the current social hot topics and advanced environmental protection concepts. - ** Diverse question types **: Common question types include multiple-choice questions, short-answer questions, etc. Some test papers have pictures for every non-multiple-choice question, which requires students to have a certain ability to read and analyze pictures. 2. ** Losing Points Analysis ** - ** Multiple-choice questions **: Some of the options are not clearly described, which will cause students to make mistakes. For example, in a certain test paper, the seventh option C is not clearly described, which will cause the highest error rate. There are also questions that are not familiar with the knowledge points and have little contact with the content in life. For example, questions 11 - 13 are unfamiliar with the knowledge points, and questions 24 and 25 are easy to remember wrongly due to lack of contact in life. - ** Non-multiple-choice questions **: For example, the high rate of losing points for question 42 was due to the lack of teaching experience and the students 'lack of understanding of the topic. The reasons for losing points for question 47 included problems in the examination, typos, and misremembering knowledge points. ##3. Teaching suggestions 1. ** Strengthening the teaching of basic knowledge ** - In teaching, students should be strengthened to grasp the basic knowledge, and more emphasis should be placed on the memory and implementation of knowledge points. The professional terms of biology should be strictly required. 2. ** Cultivate multiple abilities ** - It was necessary to strengthen the connection between biology and other disciplines, pay attention to cultivating students 'rigorous scientific attitude, train students to examine questions carefully, and improve their ability to understand the meaning of the questions. The relevant knowledge points should be extended, more theories should be combined with practice, and the hot social information should be transmitted in time to expand the students 'knowledge. 3. ** Focus on experimental teaching (for situations where there is experimental content)** - When doing experiments, he would focus on the principles of experiments, the usage of basic instruments, operating procedures, precautions, error analysis, data processing, and other aspects to improve students 'experimental skills. For designing experiments, one should start from the design methods and principles, so that students could master the rules and methods of solving problems. 4. ** Cultivate the habit of solving problems ** - Students were required to look at the process of solving the questions in recent years, and to solve the questions in a standardized manner. When answering subjective questions, they had to accurately demonstrate the process of thinking and improve their ability to express themselves. 5. ** Carry out homework training ** - Students usually had to use their exercise books to do their homework and conduct time-limited training to simulate the examination state to avoid problems such as forgetting formulas, using the wrong conclusions, and not seeing the complete conditions due to nervousness during the examination. 6. ** Group lesson preparation ** - In-depth and pragmatic work to prepare lessons every week to improve the quality of teaching. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
