If the highest score was between 90 and 100, according to the rule that every 10 points decrease in score would reduce the converted score by 0.5 points, the converted score would be 10 points for 90 - 100 points, 9.5 points for 80 - 90 points, 9 points for 70 - 80 points, 8.5 points for 60 - 70 points, 8 points for 50 - 60 points, 7.5 points for 40 - 50 points, and 7 points for 30 - 40 points. 20 - 30 points was 6.5 points, 10 - 20 points was 6 points, and 0 - 10 points was 5.5 points. Therefore, 9 points on the biology test should be converted to 5.5 points. If the highest score was between 70 and 80, the score between 70 and 80 was 10 points, 9.5 points between 60 and 70 points, 9 points between 50 and 60 points, 8.5 points between 40 and 50 points, 8 points between 30 and 40 points, 7.5 points between 20 and 30 points, 7 points between 10 and 20 points, and 6.5 points between 0 and 10 points. In that case, a score of 9 on the biology test should be converted to a score of 6.5. Read more exciting novels for free

Biology elective second year of high school chapter 1 knowledge points: - Research and application of the reagent: - Pectinase: It breaks down pectins and dissects the cell wall and intercellular layer of plants, which helps to increase the juice yield of fruits and make the juice clear. Pectinase was not an type of an ester. It included polygallouronases, pectinases, pectinases, and pectinesterases. - The activity of the reagent could be expressed by the reduction of the reagent or the increase of the product in a unit of time and volume. - Control of plant pests and animal diseases: - Control policy: prevention first, comprehensive control. - Comprehensive control methods for crop pests and diseases: - Investigation of pests and diseases: According to the purpose, requirements and targets of the investigation, it can be divided into basic situation investigation, fixed-point system investigation and pest control effect investigation. The investigation was generally carried out in the form of a sample. The sample methods included chessboard, diagonal, straight, Z, and so on. There were concepts such as disease incidence rate (preliminary understanding of the harm situation), insect population reduction rate (understanding the effect after prevention and treatment), etc. The prediction of plant pests and diseases was based on the analysis and judgment of the data obtained from observation and investigation. It calculated the occurrence period, occurrence quantity, and damage degree of the pests and diseases, and issued early warnings in time for prevention and control. - Plant quarantine: The purpose is to prevent the spread of dangerous pests and weeds. The quarantine targets were seeds, seedlings, and agricultural products, including international quarantine and domestic quarantine. - Agricultural control: Take measures such as the selection of resistant varieties (such as insect-resistant tobacco), the formulation of reasonable farming systems (such as reducing the amount of pesticide used), and the establishment of scientific fertilizer and water management to directly or indirectly eliminate or suppress the occurrence and harm of diseases, insects, and weeds. Biology elective second year of high school, knowledge points: - Cell cycle and mitosis: The cell is the basic unit of an organism, and its normal growth and development requires a series of life cycles. The cell cycle referred to the entire process of cells starting from one mitosis to the next mitosis. It was mainly divided into four stages. - G1 phase (growth phase): During this period, cells grow and synthesize the required protein and organelle. - S phase (DNA replication phase): During this period, cells replicate the DNA in their genomes, ensuring that each daughter cell has complete genetic information. - G2 phase (prophase): During this period, cells grow further and are ready to enter mitosis. - M stage (mitosis stage): During this period, cells undergo mitosis, including the formation of the Spindle, nuclear division, and cell division. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Under the new college entrance examination's "3+1+2" or "3+3" model, biology as a re-election subject would adopt a grading system. First of all, the original biological scores were divided into five grades, A, B, C, D, and E. The proportion of people in each grade was about 15%, 35%, 35%, 13%, and 2%, respectively. The corresponding five points were 100 - 86, 85 - 71, 70 - 56, 55 - 41, and 40 - 30.(In some areas, the starting point was 30 points. Even if the original score was a single digit, the lowest score was still 30 points. The lowest score in Beijing was 40 points.) The points were not given according to the paper results, but the ranking in the province (or the corresponding examination area). The points were given according to the rank conversion formula: (y2 - y)/(y-y1)=(x2 - x)/(x-x1). For example, if a student's original score for biology was 80 points, the original score range for biology level B was [82 - 61], and the score range for level B was [85 - 71]. Assuming that the score after the score was X, then (82 - 80)/(80 - 61)=(85 - X)/(X - 71). After rounding, the value of X could be obtained, and this value was the score. Compared to physics, chemistry, and politics, biology might be easier to give marks. This was because the people who took the biology exam covered many levels of students. Not only were there top students, but ordinary students and backward students also preferred biology. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Guangdong biological assessment uses the grading method. Firstly, the paper scores of each elective examination subject in politics, geography, chemistry, and biology were divided into five grades, A, B, C, D, and E, from high to low. The proportion of people in each grade was about 17%, 33%, 33%, 15%, and 2%. 30 points were used as the starting point for the calculation of the level score. The full score was 100 points, and 1 point was 1 level. Then, according to the law of proportion, the paper scores of the candidates from A to E were converted into five points, 100 - 83, 82 - 71, 70 - 59, 58 - 41, and 40 - 30, respectively, to obtain the grade points of each candidate. In this way, the biology paper's surface score could be converted into a comparable grade score for the college entrance examination's total score. <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 full marks for geography and biology were both 100 points, and the passing score was 60 points. 38 points did not reach the passing line, so it was not considered a high score. In the general exam, the results were divided into four grades: A, B, C, and D. 60 - 74 points were defined as passing grade (C grade), 59 points and below were considered failing grade (D grade), and 38 points belonged to the lower grades. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
