What are the contents of the high school biology subject discussion questions?
The content of the high school biology seminar was as follows: 1. * * Teaching philosophy ** - In the context of the new curriculum, it was necessary to discuss how to use the "student-oriented" approach to enhance students 'initiative. From letting students learn in the past to students taking the initiative to learn, it was necessary to fully tap into students' interest, change the traditional teaching method of teachers filling the classroom, and let students actively participate in learning, so as to realize the concept of "teaching is not teaching". - The transformation of the role of teachers was also one of the topics of discussion. For example, from the users of teaching materials to the developers and creators of teaching materials, the new era should pay attention to the cultivation of the core qualities of biology. 2. * * Teaching Mode and Method ** - For example, the discussion of project-based teaching methods based on the history of science, such as the explanation of the structure of DNA based on the history of science, could bring out the students 'subjective initiative, improve the students' ability to analyze data, cultivate critical thinking, and provide a new model for the teaching reform under the new curriculum standards. - There was also a discussion on the application of the smart classroom in high school biology, including the distinction between the tablet's pre-class, in-class, and after-class functions, the emphasis on accurate analysis of learning before class, and the adaptation of the teaching focus. 3. * * In terms of improving students 'learning ability ** - Discussions on the different stages of high school biology learning, such as the importance of returning to the textbook when the foundation was weak, including paying attention to the textbook's bold words and chapter summary, self-summary or using books such as "Basic Knowledge of High School Biology" to construct a knowledge framework, reciting and memorizing knowledge, repeated training to steadily improve, and so on. - Special training to accurately brush the questions. Through targeted use of the biology college entrance examination real questions, test points classification of special training to improve the accuracy and speed of solving questions. - It was a discussion on the learning methods of the second compulsory subject of high school biology, genetics. For example, it could explain the complicated and boring knowledge points in an interesting way, and test the learning results through the accompanying exercise book. 4. * * Teaching Evaluation ** - To discuss the impact of the college entrance examination evaluation system on teaching design. For example, the "one core, four levels, four wings" college entrance examination evaluation system covered the purpose, content, and requirements of the college entrance examination. The college entrance examination proposition was based on three lines (core value gold line, ability accomplishment silver line, situation carrier series line) as the framework, presenting the characteristics of "no value, no question; no thinking, no proposition; no situation, no question". Teachers should study the relevant college entrance examination evaluation materials to improve their ability to control the direction and evaluation of the new college entrance examination. - They discussed how to improve the quality of classroom teaching, such as through the evaluation activities between teachers, such as the evaluation of the open class teaching of the structure of DNA. They evaluated the teaching content of different teachers, the content of the class, the details of the teaching, whether to return to the teaching materials, and how to play the role of the history of science in educating people.

Junior high school biology questions must be memorized
The following are some of the must-memorize content that might be involved in the junior high school biology questions: - In terms of biological structure, cells were the basic units of biological structure and function. The structure of an animal was cell → tissue → organ → system → animal, while the structure of a plant was cell → tissue → organ → plant. - Biological and environmental parts: The composition of the ecosystem includes biological parts (producers, consumers, decomposing) and non-biological parts (sunlight, air, water, etc.). The substances and energy in the ecosystem flow along the food chain and food web, and the energy transfer is one-way and diminishing. - Green plants in the biosphere: the reaction formula, essence (synthesizing organic matter, storing energy), significance (providing food and oxygen for themselves and other organisms); the reaction formula, essence (decomposing organic matter, releasing energy) of the respiratory process and its importance in plant life activities. - Human Physiology: The nutrients of the human body (such as sugar, fat, protein, vitamins, water, and mineral salt); the composition of the digestive system and the functions of various organs; the digestion and absorption process of food; the composition of the respiratory system and the gas exchange process.(including the gas exchange in the lungs and tissues); the composition of the blood circulation system (heart structure, blood vessel type and function, blood composition and function); the blood circulation pathway (body circulation and lung circulation); the composition of the urine system and the process of urine formation (glomerular filtering and glomerular reabsorption). - Biological inheritance and variation: genes control biological traits, the law of gene transmission between parents and offspring (such as trait separation ratio), concepts such as relative traits, dominant genes, latent genes, dominant traits, latent traits, etc.; types of biological variation (heritable variation and non-heritable variation) and their reasons. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
High school biology common error-prone questions and answers
Here are some common questions and answers to them: ** 1. Physical basis of cells ** - Error-prone problem: Believes that all sugar is an energy source. - Answer: Wrong. Not all sugar was an energy substance. For example, Ribose and Deoxy Ribose were the components of DNA, and Cellulose was a component of plant cell walls. They could not be used as energy substances to supply energy to cells. - Error-prone question: Believing that macro elements are important in the body and micro elements are not. - Answer: Wrong. Although there were many large amounts of elements in the body, trace elements also played an irreplaceable role in the body. For example, iron was an important component of hemoglobin. A lack of iron would lead to iron-deficiency leukemia. ** 2. In terms of the protein and the protein ** - Error-prone problem: Believing that the protein only works inside the cell. - Answer: Wrong. The digestive system could be activated in the digestive tract. - Error-prone problem: It is believed that the relationship between the activity of the protein and temperature and pH. - Answer: Wrong. The relationship between the activity of the protein, temperature, and pH. The activity of the protein was the highest at the optimal temperature and pH. The activity of the protein would decrease when it was lower or higher than this value. However, the high temperature and the overly acidic or overly basic pH. ** 3. Photosynthesis and cell breathing ** - Wrong question: Think that plants only photosynthesize when there is light. - Answer: Wrong. Plants carried out photosynthesis and respiration at the same time when there was light, but the oxygen and organic matter produced by photosynthesis might be more than the oxygen and organic matter consumed by respiration. The overall performance was the release of oxygen and the accumulation of organic matter. - Wrong question: Think that only the mitochondria are the places of oxygen. - Answer: Wrong. The first stage of oxygen breathing was carried out in the cellular matrix. The glucose was broken down into gly ruvate and a small amount of [H], releasing a small amount of energy. The second stage was carried out in the mitochondria matrix. The reaction of gly ruvate and water produced carbon dioxide and a large amount of [H], releasing a small amount of energy. The third stage was carried out on the inner membrane of the mitochondria.[H] combined with oxygen to produce water, releasing a large amount of energy. ** 4. Meiosis and fertilisation ** - Error-prone problem: think that the same type of DNA only exists during the process of Meiosis. - Answer: Wrong. Homoeotic embryos also existed in the body cells. During the process of Meiosis, the homological embryos underwent special behaviors such as association and separation. - Wrong question: Think that fertilisation is just a simple combination of sperm and egg. - Answer: Wrong. During the process of fertilisation, the head of the sperm entered the egg cell while the tail remained outside. At the same time, the nucleus of the sperm fused with the nucleus of the egg cell. Half of the embryos in the fertilized egg came from the father and the other half came from the mother. In addition, almost all the genetic material in the fertilized egg came from the mother. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following are some of the answers and analysis of the biology test questions of the first mock exam of the third year of high school in 2023 in Shandong Province: 1. Single choice questions 1. Answer: B. - Analysis: During the synthesis of cell membrane shaping protein, the location is provided by the Ribosome, and the power is provided by the mitochondria.(The main energy supplier in the cell, the plastids are mainly found in plant cells and are mainly related to photosynthesis, not involved here), A is wrong; the "molecular garbage bag" is a vesicle, mainly composed of lysomes and protein, B is correct; the "recycling factory" may be a lysoma, and the "component" may be an amine acid.(Because it is a product of protein decomposition, not a primer), C error; The organelle that can form vesicles in human cells includes the plasmatic reticule and the Golgi apparatus, but the centric body cannot form vesicles, D error. 2. Answer: A. - Analysis: The V-disorderly transport of H+ from the cellular matrix into the vesicle was a process that consumed ATP. It was an active transport, not an auxiliary spread. A was wrong. Inhibition of the activity of Cys transporter on the tonoelle would affect the process illustrated in the diagram, resulting in abnormal function of the mitochondria. B was correct. Cys entered the vesicle against the concentration slope by using the potential energy of H+. It was an active transport. C was correct. The process illustrated in the diagram indicated that there was a connection between the vesicle and the mitochondria. There was both division of labor and cooperation. D was correct. 3. Answer: D. - Analysis: The cells in the root meristematic zone of onions had no fat, so orange granules could not be observed with Sultan III staining. A was wrong; The cells in the root meristematic zone of onions became square and tightly arranged after being dissociated, rinsed, stained, and made into slices. B was wrong; The widest color of the green tube-shaped leaf on the filter paper was the cyanophile a (blue-green), C was wrong; The color of the purple onion scale leaf was cyanophile, which could not be extracted with absolute alcohol (absolute alcohol was used to extract the color in the plastids). D was correct. 4. (As the question did not give all the questions about this question, the answer and analysis could not be given accurately.) 2.
