Hunan 2022 college entrance examination biology
In the 2022 Hunan college entrance examination, biology was used as a re-election subject to be graded. The specific scoring method was as follows: 30 points were used as the starting point for the conversion of grades. According to the examinee's paper score, from high to low, they were divided into five grades, A, B, C, D, and E. These five grades represented 15%, 35%, 35%, 13%, and 2% of the examinee's total ranking. The paper scores of the candidates in grades A to E were converted into five points, the corresponding points were 100 - 86, 85 - 71, 70 - 56, 55 - 41, and 40 - 30. The full score of each level was 100 points. Each level was continuously awarded points according to the score interval of 1 point and 1 grade. The score range of each level ranged from 17 to 10 points. During the conversion, the conversion rule was used, and the conversion rule was determined by the formula (Y2 - Y)/(Y-Y1)=(T2 - T)/(T-T1).(Where Y represents the examinee's actual paper score, Y1 and Y2 are the upper and lower limits of the grade range of the examinee's actual paper score, T represents the converted score, T1 and T2 are the upper and lower limits of the grade range of the examinee's converted score.) The examinee's paper score is converted into grade score. After the conversion, the student's score ranking remains unchanged. The final score is obtained after the mathematical conversion and rounding. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

What are the biology questions in Hunan college entrance examination?
From the 2024 Hunan college entrance examination biology proposition situation, its biology big question examination content covers many aspects. The first was to conduct an examination from the ecological aspect. For example, in the new curriculum standard volume, the theme of the water quality assessment was to examine the reasons for monitoring the nitrogen element, the physiological process of carbon neutrality in mangroves, and the key role of birds and other consumers in the ecosystem. There was also knowledge about the ecosystem related to the construction of artificial grasslands in urban areas, such as the impact of the construction of artificial grasslands on the ecological environment, the effect of removing eutrophy deposits in lakes on the restoration of the ecosystem, the ecological engineering principles followed by transplanting plants, and the relationship between the intensity of the effect of temperature and pests on the population density of the vegetation in the grasslands. The second is related to the ability of experimental inquiry. For example, National Volume A requires the design of an experimental scheme to verify that protein fragments can appear in the lysomes of engulfing cells; The new curriculum standard volume requires the design of an experimental scheme to detect the AIDS virus in blood samples; National Volume A takes genetic engineering to express the target protein as the background, examining the principle and purpose of the key links such as double digestion of the plasmid-carrier and preparation of competent cells. Thirdly, in terms of production and life, the new curriculum standard paper gave the practical problems of breeding that the white thorn melon was favored by consumers and the yield of female plants was high, and required the use of genetic crossing method to screen the pure body of the white thorn female plant; National Volume A focused on the theme of rational use of disinfectant to reduce infectious diseases, examining the key points of investigation such as microorganisms cultivation, bacteria counting, coating plate, analysis of experimental results, etc. In addition, they also paid attention to the examination of the foundation of the subject, such as the transportation mode and mode of action of important plant hormones. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

2021 Hunan college entrance examination biology 70, how many points can be awarded?
In 2021, Hunan Province's new college entrance examination biology was a re-elected subject. Each re-elected subject was originally divided into 100 points. When converting, 30 points were used as the starting point for the grade conversion, and 100 points were full marks. First, the original scores of the candidates for each re-elected subject were divided into five grades, A, B, C, D, and E, from high to low. The proportion of people in each grade was about 15%, 35%, 35%, 13%, and 2%, respectively. The corresponding score range was 100 - 86 points for Grade A, 85 - 71 points for Grade B, 70 - 56 points for Grade C, 55 - 41 points for Grade D, and 40 - 30 points for Grade E. If the original biological score was 70 points, it would belong to the C grade, and the score range would be 70 - 56 points. However, based on the original score of 70 points, it was impossible to know the exact score after the score was assigned. This was because it still needed to be converted according to the principle of proportional conversion and the original score of other examinees in the same grade. The conversion result would be presented as a whole number according to the rule of "rounding". <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Biology into the cell college entrance examination questions
In the college entrance examination, the common questions for the "Entering the Cell" section were as follows: ** 1. Multiple choice questions ** 1. ** Judgment of Prokaryota and Eukaryote ** - [Test format: Give some creature names and determine whether it is a prokaryota or a eukaryota.] For example, judging by the qualifier in front of the word "fungus" or "algae". For example, those with the word "bacteria" in front of the word "rod"(such as yogurt),"ball"(such as streptococci),"spiral" and "arc"(such as vibrios) were all bacteria and prokarytes. However, those with the word "bacteria" and "algae" were not necessarily prokarytes. For example, yeast, mold, green algae, brown algae, and red algae were all eukarytes. - It would also involve the examination of the differences between the structure of prokaryonic cells and eukaryonic cells. For example, prokaryonic cells did not have any microorganisms and could not undergo mitosis, but they could proliferate in the form of two divisions. Prokaryonic cells did not contain mitochondria, but some could carry out knowledge points such as oxygen breathing. 2. ** The variety of cells is related to unity ** - For example, the similarities and differences in the structure and function of different cells were examined. For example, although nitrafying bacteria could not carry out photosynthesis, they were autotrophs. Cyanacea did not have plastids, but they were producers in the ecosystem. - It would also involve the examination of cell theory. For example, cell theory believed that all organisms were composed of one or more cells; cells were the units of structure and function of all organisms; all cells must be produced by existing cells. Based on this, it might examine the variety, inheritance, unity of organisms, and the understanding of whether the mutation was directed. 3. ** Virus related ** - Examining the structure of the virus, the knowledge of parasitism, reverse replication, immunity, and so on. For example, the poliovirus has been artificially synthesized by scientists. They may examine the similarities and differences in structure and function between synthetic viruses and natural viruses. For example, synthetic viruses can cause poliovirus in mice, but their toxicity is much lower than that of natural viruses. Viruses had no cell structure, no cell membrane, and could not carry out cell breathing, but viruses, E. Coli, and yeasts all contained genetic material. The application of viruses in biology and medicine will also be examined. For example, deactivated viruses can be used to induce animal cell fusion, mice can be used to prepare monoclonals with specific viruses, genetic engineering can be used to transform bacteria (not plant cells), and viruses that have been deactivated or weakened can be used for immune prevention. ** 2. Non-multiple choice questions ** 1. ** Curved Questions ** - For example, taking the curve of the effect of the concentration of growth hormone on the growth and development of plants as an example, it involved steps such as identifying the mark (figuring out the meaning and connection of the vertical and horizontal coordinates), the surging point (figuring out the meaning of the special point on the coordinate map), and the line analysis (analyzing the change trend of the curve and its meaning according to the meaning of the vertical and horizontal coordinates). It was possible to examine the sensitivity of different plant organs (such as roots, stems, and buds) to the concentration of the growth hormone, the distribution of the growth hormone concentration in the phototropism experiment of the stem, and the selection of the growth hormone concentration when cultivating the seedless tomato based on the principle of growth hormone. 2. ** Form Information Type Questions ** - The information reflected by this type of question was relatively hidden. For example, a table was given to show the levels of two hormones in the blood that were closely related to the activity of the gallbladder in the two groups of people who were deficient in iodination and those who were not deficient in iodination. The steps to solve the problem included carefully reading and understanding the materials in the table, making clear the information reflected in the table, conducting a comprehensive analysis of the materials in the table, grasping the internal relationship between the table and the questions, and combining the problems in the materials with the knowledge of the teaching materials to prove them. Finally, a summary was made. 3. ** Diagram Questions ** - examine a particular structure or physiological process of an organism in the form of a diagram or diagram. For example, the changes in the nuclei during cell division were examined. The nuclei in the cells were composed of DNA and protein. During cell division, the nuclei would be duplicated. As the cells divided, the nuclei would be divided into two parts with the same shape and number, which would enter two new cells respectively. After cell division, the new cells and the original cells would have the same shape and number of nuclei. There were also differences in the division methods of animal cells and plant cells.(The cell membrane of an animal cell collapses inward from the middle of the cell and splits into two cells; a plant cell forms a new cell membrane and cell wall in the center of the original cell and splits into two cells). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
