The Analysis of the Questions and the Answer in the Biology Course of Senior High School
The following are some questions and answers that might be involved in the high school biology seminar: ** I. Problems related to the metabolism of cells ** 1. ** Question **: briefly describe the process of scientific discovery of the essence of the enzyme and the characteristics of scientific exploration. - Before Pasteur, he believed that fermentation was a pure chemical reaction and had nothing to do with life. Pasteur and Liebig respectively proposed that the fermentation in brewing was related to living yeast cells. Without living cells, sugar could not be turned into alcohol, and that the fermentation was caused by certain substances in the yeast cells, and these substances could only play a role after the yeast cells died and cracked. Through experiments, Bichner proved Liebig's point of view was correct, saying that the substance that caused fermentation was a zymase, but what exactly was the zymase was still unclear. Later, Sumner extracted urease crystals with high purity from sword bean seeds for the first time and proved that urease was a protein. This process showed that scientific discoveries were not smooth sailing. Many scientists needed to repeatedly demonstrate, debate, and experiment to reach scientific conclusions. 2. [Question: What is the relationship between the metabolism of the cell and the metabolism of the cell?] - Cell metabolism is composed of a series of chemical reactions in the cell. These reactions need to be carried out at high speed under normal temperature and pressure, and they require the catalyze of an enzyme. Because the reaction environment inside the cell was at normal temperature and pressure, in order to make the chemical reaction proceed quickly, the reaction required the activation energy to be reduced. 3. [Question: How do you determine if an protein is an protein?] - [Answer analysis: Biuret reagent can be used to determine whether this type of protein is a protein.] ** 2. Questions related to the ability to explore biological experiments ** 1. [Question: In the college entrance examination, how do you test your ability to design an experiment plan?] - For example, the 30th question of National Volume A required students to design an experimental plan to verify that protein fragments could appear in the lysomes of engulfing cells. The 32nd question of the new curriculum standard required students to design an experimental plan to test the AIDS virus in blood samples. This tested the students 'ability to use basic experimental methods and techniques to solve new problems. 2. [Question: Using genetic engineering experiments as an example, how does the biology college entrance examination test the understanding of the principles and objectives of the key links of the experiment?] - Question 38 of National Volume A used genetic engineering to express the target protein as the background. It examined the principles and purposes of the key links such as the double digestion of the plasmid-carrier and the preparation of competent cells. It allowed students to feel the rigorous and realistic characteristics of scientific research in the process of solving common problems in scientific research, so as to examine their understanding of the principles and purposes of the key links of the experiment. ** 3. Questions related to the application of biological knowledge in production and life ** 1. [Question: Give an example of how the college entrance examination biology questions reflect the application of biological knowledge in solving practical production and life problems.] - ** Answer Analysis **: Question 34 of the new curriculum standard volume mentioned the practical problem of the high yield of the female plants of the white thorn melon being favored by consumers. Students were required to use genetic crossing methods to screen out the pure hybrids of the female plants of the white thorn melon to solve the problem of high yield. Question 37 of National Volume A focused on the theme of rational use of disinfectant to reduce infectious diseases. It examined the key points of the exploration process such as microorganisms cultivation, bacteria counting, coating plates, and analysis of experimental results. It guided students to use the basic methods of scientific inquiry to solve practical problems in production and life, reflecting the application of biological knowledge in solving practical production and life problems. ** IV. Core literacy and teaching-related issues in biology ** 1. [Question: How to implement the core knowledge of biology in biology class?] - ** Answer Analysis **: Taking the classroom teaching " Passive Transportation " as an example, at the beginning of the class, the students were used to think about life phenomena, stimulate the curiosity of students to explore new knowledge, arouse the enthusiasm of students in the form of question strings, set up independent inquiry and group discussion sessions, and let students feel a sense of participation. In the teaching process, they combined life examples to understand the knowledge points, such as explaining the principle of water entering and leaving the cell. This could well fulfill the requirements of developing students 'scientific thinking and social responsibility in the core accomplishment of biology. In addition, the course " Gene Mutation " focused on the occurrence and mechanism of cancer. It guided the students to analyze and explore the concept, essence, characteristics, significance, etc. of gene mutation independently. It was also helpful to improve the students 'core biological quality. 2. ** Question **: How does the inter-school biology exchange activity promote teachers 'teaching? - Take the inter-school biology exchange between Jigang High School and Laiwu No.1 Middle School as an example. The inter-school exchange provided a platform for teachers to exchange teaching models and study school-based curriculum. Through the exchange, teachers could learn the experience of developing and implementing the biology school-based curriculum in other schools. For example, the teachers of Jigang High School realized that the content of the biology school-based curriculum in Laiwu No.1 Middle School was rich and layered. They could also learn different classroom teaching methods, such as teacher guidance and student inquiry in the classroom of Laiwu No.1 Middle School. They could truly realize the student-centered teaching mode, thus promoting the updating of teachers 'teaching ideas and the reform of teaching methods, and improving the teaching level of teachers.

What are the lighting methods in cell phone photography?
In cell phone photography, there were mainly the following lighting methods: 1. ** Light **: The direction of the light is the same as the direction of the phone, which can fully display the color, shape and other details of the subject facing the camera. 2. ** Side Light **: The light shines from the side of the subject, which can produce a clear contrast between light and dark, and highlight the texture and outline of the object. 3. ** Backlight **: Light shines from behind the subject. Backlight photography could clearly capture the texture of leaves, petals, and other things. It could also capture the elegant hair, adding a sense of aesthetics to the photo. It could also capture the silhouette effect, giving the photo a sense of mystery. However, when taking portraits or group photos, one had to pay attention to the composition, posture, distance, etc., so as not to affect the appearance of the outline. 4. ** Side Backlight **: The light shines from the back of the subject, which has the characteristics of both backlighting and side lighting. 5. ** Top Light **: The light shines from the top of the subject. This lighting method may produce a strong shadow effect. 6. Soft Light: refers to the relatively soft light in the shooting environment. Most of it is scattered light, and the direction is not strong. It is common in cloudy days, dusk, or indoor scattered light environments. It can also be artificially created by soft lights, soft light boxes, and so on. When shooting in a soft light environment, the subject would generally not produce shadows or only produce very light shadows. It could express the color, pattern, and other characteristics of the subject in a delicate and soft manner. 7. ** Hard light **: Opposite to soft light, it has a strong directionalness and can produce deeper shadows on the screen, such as direct sunlight on sunny days, light from searchlights, and spotlight light in the studio. Shooting in a hard-light environment can make the contrast between light and dark in the picture stronger, and the shape and outline of the subject will be more prominent. However, when the light ratio is too high, it may cause the light or dark parts to lose their level. If necessary, you can use the HPR function of the phone to increase the level (but HPR may make some images that need to emphasize the light and shadow effect lack the three-dimensional feeling). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
