Hunan Biology 2023 True Questions and Answer
Some of the true questions and answers of the Hunan Volume of the National College Entrance Examination in 2023 (reference version) are as follows: 1. Single choice questions 1. After the female emperor penguins lay eggs, the male emperor penguins were responsible for hatching the eggs. They did not eat during the incubation period. - The misstatement was that the content of N in the egg white protein of the emperor penguin was higher than that of C. Because the male emperor penguins mainly consumed their body fat for energy during the incubation period, the emperor penguins produced water during the synthesis of their DNA, glycan, and protein. During the incubation process of the emperor penguins 'eggs, there were changes in the types of mRNa and protein. 2. Regarding cell structure and function: - The wrong description was that the membrane of the mitochondria was rich in the production of carbon dioxide. In fact, if the cell skeleton was destroyed, it would affect cell movement, division, and division. Nucleoli contained components such as DNA, R A, and protein, which were related to the formation of Ribosome. The ER was a membrane pipeline system, which was the synthesis, processing, and transportation channel of protein. 3. Drinking too much is harmful to human health. In the human body, alcohol is first converted to aldo, which is then converted to actic acid under the action of aldo dehydrogenases (ALDH2), and finally converted to carbon dioxide and water. Cephalothems could suppress the activity of ALDH2. A mutation in the ALRH2 gene causes a decrease or loss of ALRH2 activity: - For drinkers, the clinical symptoms of East Asians were more obvious after drinking; patients should avoid consuming alcoholic beverages or food during the period of taking cephem drugs; the decreased tolerance of alcohol in people with ALRH2 gene mutation indicated that the gene controlled the trait; currently, oral ALRH2 preparations could catalyze the conversion of Zhang Jia to acetate, thus relieving poisoning. 4. "The fragrance of the rape blossoms assails the nose." Rape was one of the main oil crops. Pollen and nectar could be used as food for insects. - The correct description was that rape attracted insects through chemical information; insects, bees and rape co-evolved; the relationship between bees and rape was a mutualistic symbiosis; bees and insects could increase the richness of soil microorganisms after collecting honey. 5. Food preservation methods included drying, marinating, low temperature preservation, and high temperature treatment. - The correct description was: drying reduced the moisture content of food, making it difficult for microorganisms to grow and reproduce, thus prolonging the preservation time of food; marinating added salt to create a hypertonic environment to suppress the growth and reproduction of microorganisms; low temperature preservation could suppress the life activities of microorganisms, but low temperature was not completely beneficial to food preservation; high temperature treatment could kill most of the microorganisms in food and destroy the activity of the microorganisms in food. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Analysis and Reflection on the 2020 Biology College Entrance Examination Questions
The 2020 biology college entrance examination questions had the following characteristics: - ** Value Guidance, Quality Guidance ** - ** Integration into real situations, cultivating social responsibility **: Combining the characteristics of biology, the college entrance examination questions are integrated into social hot topics, such as the new epidemic situation material. For example, question 28, with the detection and treatment of the new crown as the background, examined the immune response of the body, the detection of viruses and antibodies, and the principle of preparation of monoclonals. It not only examined the knowledge points, but also allowed the students to understand the social hot spots related to biology and enhance their confidence in defeating viruses; Question 24 was based on earthworm decomposition technology. It examined the composition of the ecosystem and introduced the concept of organic matter recycling. Combined with the topic of domestic waste classification, it guided students to understand the significance of waste classification and enhance their sense of social responsibility. - ** Based on subject accomplishment, closely follow the teaching focus **: The test paper focuses on the core accomplishment of the subject and the key teaching content, and strengthen the scientific thinking and scientific inquiry ability. Heredity questions were a typical test of scientific thinking ability. For example, the 21st question was a classic genetics question, which required students to master the basic laws of genetics and flexibly use them for trait analysis and genetic probability calculation. The 32nd question was about the inheritance of fruit fly hybrids and comprehensive mutation test points, which introduced the verification experiment design. Students had to design experiments to verify the reasons for the emergence of special mutants on the basis of mastering the laws of genetics, which required scientific inquiry ability. The 31st question used microbiology experiments as the background to design a complete scientific research process. It comprehensively tested the students 'comprehensive scientific inquiry ability. - ** Initiate green development, reflect environmental friendliness **: The test questions select typical scenes from daily life, guide students to use scientific methods to analyze and understand life phenomena, establish healthy living concepts, enhance environmental awareness, and advocate harmonious development between man and nature. Reflection: - The importance of comprehensive application of knowledge: From the test questions, students need to combine the knowledge of different sections, such as immunity, virus detection, and other knowledge to answer questions related to the new crown. This suggests that in the teaching and learning process, we should pay attention to the construction of the knowledge system, rather than simply memorizing the knowledge points. - ** Requirement of integrating theory with practical ability **: Many questions are based on practical situations, such as earthworm disposal of garbage, the situation of the new crown epidemic, etc. This requires students to learn biological knowledge without being separated from real life. They must learn to use the knowledge they have learned to explain biological phenomena in life, and be able to flexibly use the knowledge to solve problems according to the actual situation. - ** The importance of experimental inquiry ability **: From the questions involving experimental design and result analysis, it can be seen that the examination of students 'experimental inquiry ability is more intense. In the teaching, experimental teaching should be strengthened to cultivate students' ability to ask questions, make assumptions, design experiments, and analyze results. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Talking about the biology college entrance examination questions
The biology college entrance examination questions could be evaluated from the following aspects: 1. ** Analyzing the basic situation of the exam ** - When the papers were being marked, they began to prepare and record the students 'answers, such as which questions were answered well, which questions lost more points, whether they lost points for knowledge or skill, whether it was a common phenomenon or an individual phenomenon, and so on. After the statistics and analysis, he wrote the lesson plan. During the evaluation class, he would briefly introduce the basic situation of the test to the students, including the analysis of the test paper, the analysis of the answer, and so on. 2. ** Commenting on mistakes ** - There was no need to explain the entire test paper from beginning to end. For questions with no or very few mistakes, they usually do not comment or simply mention them; questions that some students make mistakes can be commented on according to the situation; questions that most students make mistakes (often confusing and comprehensive) should be emphasized. 3. ** Set up questions for students to explore ** - With the students as the main body, let the students discuss and analyze, explore and correct mistakes, summarize and solve problems. Students could be allowed to explain the less difficult questions. Students would be given more opportunities to do so during the end-of-term review tests. For questions that spanned a long distance and were comprehensive, and the students generally felt difficult, the students were allowed to discuss them first, and then the teachers would form a reference answer. This would arouse the students 'enthusiasm and improve their ability to analyze and solve problems. 4. ** Simulation training available ** - The exercises and variant exercises were designed around the questions in the test paper. For example, according to the knowledge points, skills, skills, methods, etc. examined in the college entrance examination biology questions, variant exercises were compiled from multiple angles to allow students to deepen their understanding and mastery of such questions from different angles. 5. ** Guide students to give feedback and summarize ** - Students were given the opportunity to summarize and reflect. They were encouraged to create a book of mistakes and sort out the typical mistakes to improve the effect of the paper evaluation. When commenting on the specific content of the college entrance examination biology questions: 1. ** Integration into the aspect of establishing morality and cultivating people ** - For example, the new curriculum standard paper with the theme of Yundao Lake in Xiameng can guide students to think about the significance of protecting biological richness and convey the concept of "green water and green mountains are golden mountains and silver mountains"; National Volume A takes the protection of endangered species birds as an example to guide students to think about the biological significance of protecting endangered species and establish the consciousness of action to protect biological richness. 2. ** Outstanding experimental inquiry ability ** - For example, the national volume A required the design of experimental programs to verify that protein fragments could appear in the lysomes of engulfing cells. Students should be guided to understand how to use basic experimental methods and techniques to solve new problems. The new curriculum standard volume required the design of experimental programs to test the AIDS virus in blood samples. Students could discuss a variety of programs, such as CPR technology. National Volume A used genetic engineering to express the target protein as the background to examine the principles and objectives of the relevant key links. It was to let students feel the rigor of scientific research. 3. ** Close contact with production and life ** - The new curriculum standard paper gave the test questions of practical problems in the breeding of white thorn melon, guiding students to solve the problem of high yield by genetic crossing methods, from "solving problems" to "solving problems"; National Volume A focused on the topic of rational use of disinfectant to reduce infectious diseases, guiding students to use scientific inquiry basic methods to solve practical problems and strengthen application orientation. 4. ** Strengthening the subject foundation examination ** - For example, National Volume A focused on the transportation mode and action mode of plant hormones to test the depth of understanding and cognitive breadth of hormone regulation mode. Students should be guided to accurately understand and flexibly apply the necessary knowledge, so as to reduce the phenomenon of memorization and mechanical brushing. When commenting on multiple-choice questions, you can analyze the test points, test directions and solution ideas one by one like Mr. Wang Dongkuan, analyze the knowledge points in depth, and exchange effective solution skills; When commenting on subjective questions, you can refer to Mr. Jia Zhangfang's opinions, analyze the characteristics of multi-question setting, clear hierarchy, reflecting the degree of distinction, examining the core accomplishment of the subject, etc., and put forward opinions on new lessons and review according to specific cases, attach importance to teaching materials, rely on experimental teaching, cultivate the consciousness of standard answering questions, etc. <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>
