Due to space limitations, it is impossible to provide the complete content of the biology notes for the 2024 college entrance examination. However, the new college entrance examination biology knowledge points included many aspects: - In terms of proposition, the biology college entrance examination in 2024 carried out the idea of ecological civilization in the new era and carried out the fundamental task of establishing morality and cultivating people. For example, relevant ideas should be integrated into the ecological examination, and students should be guided to think about the value concept of protecting the significance of biological richness through specific questions. At the same time, the national A volume and the new curriculum standard volume should pay attention to the scientific selection of talents and the function of guiding teaching during the proposition, so as to maintain the style of proposition in recent years and strengthen the examination of necessary knowledge and key abilities. - From the point of view of knowledge points, one needed to master basic knowledge points such as the transportation mode and mode of action of plant hormones, as well as knowledge related to experimental exploration ability, such as designing experimental schemes (such as verifying the appearance of protein fragments in the lysomes of engulfing cells, testing the virus in blood samples, etc.), optimization of experimental procedures, analysis of experimental results, as well as genetic engineering related knowledge such as double digestion of plasmid-carriers, the principle and purpose of competent cell preparation, etc. - In terms of solving practical problems, they should be able to use genetic crossing methods to solve the problem of high-yield crop breeding, and use knowledge such as microorganisms cultivation and bacteria counting to solve practical problems such as rational use of disinfectant to reduce infectious diseases. - At the same time, the new college entrance examination biology continued to increase the intensity of the subject foundation examination, multi-dimensional examination of the necessary knowledge understanding and mastery of depth and breadth, covering compulsory and elective content, these are the key content that needs to be covered when sorting out biology notes. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
In 2024, Shanxi's college entrance examination was still the traditional college entrance examination. In 2025, Shanxi would begin to implement the new college entrance examination. If they took the Shanxi high school biology college entrance examination in 2025 or later, they would adopt the new college entrance examination model. At that time, the full score of biology would be 100 points, and the grade conversion points would be included in the total score of the college entrance examination. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
