High school biology illustrated shorthand textbook

The following are the answers to some of the questions in the Jiangsu version of the high school biology compulsory textbook: Chapter 1: The molecular composition of cells The Elements and Inorganic Compound in the Cell - ** Speculation Questions ** - Among the chemical elements that made up living things, C, H, O, and N were the most abundant. - Free water was a good solution for many ions, not bound water. - If muscle weakness occurs, the substance that may be lacking is calcium. - ** Usage Questions ** - The trace elements were iron, mn, zn, copper, b, al, co, and se. - The carbon exists in the form of carbon dioxide, oxygen in the form of water, hydrogen in the form of water, calcium in the form of carbon dioxide, phosphorus in the form of dipotassium hydrogen orthhosphate, and potassium in the form of kci. They are involved in the composition of substances in the body; Na ions maintain the stability of the osmonic pressure of the extra-cellular fluid; K ions participate in the activation of more than 60 kinds of membranes during plant growth and development; Ferrous ions are the components of many membranes; and Magnesium ions are an important component of the phylls. - Legume plants such as alfalfas and soybeans had a nitrogen fixing bacteria at the roots, which could help them survive the winter. - Free water was a good solute. The ions and molecules needed for cell life could be dissolved in it and flow with the water to participate in the reaction. Metabolic waste could also be discharged from the body through water. ** Section Two: Carboids and Lipids in the Cell ** - ** Speculation Questions ** - Glycogen and glucose were the main energy substances, fat was an important energy storage substance, and Cellulose was a plant cell structure substance that could not be used as an energy substance. - Lipids were divided into fats, lysomes, and steroids, but lysomes did not belong to steroids. - It was not advisable to reduce overweight weight only by reducing the intake of sugar and fatty foods. It was also necessary to combine it with moderate physical exercise. - ** Usage Questions ** - Plant cells contained starch and starch, and the process of making syrup was similar to the biological method. - The second biological method was used to utilize the raw material of the Cellulosic. - Celluloses and other glycans were important structural substances in plant cells, while glucose was the main energy source for life activities. - Ferlin's reagent could only identify reducing sugar. Sweet potatoes mainly contained non-reducing sugar such as starch, so it could not be used to identify them. However, Sultan III staining solution could be used to detect the fat in sweet potatoes. ** Section Three: The Nucleic Acid and Nucleic Acid in the Cell ** - ** Speculation Questions ** - Nucleic acid in the human body was composed of eight kinds of nuclei (adenine deoxy, guanine deoxy, cystine deoxy, thymine deoxy, adenine Ribo, guanine Ribo, cystine Ribo, and uracil Ribo). Uridine Ribo was composed of uracil, Ribo, and Phosphoryl. - The seeds of wheat, sorghums, and other plants are rich in starch, while animals such as cattle and sheep are rich in protein and fat. - ** Usage Questions ** - In contrast to the "food pyramid", if you eat too much dessert and meat, you may be obese, and if you eat too little vegetables and fruits, you may lack vitamins. - Mung beans may contain more starch; it is not possible to judge whether they are nutritious based on the content of protein; the cell composition of beans cannot be separated from protein. Cell structure and life activities (Part) - In the content related to organic matter in cells, there were various statements: - Not all kinds of sugar could be used as a plant energy material. Ribose and deoxy sugar formed the genetic material, and the plant cell wall made of Cellulose could not be used as an energy material. Therefore, it was wrong to say that all kinds of sugar could be used as a plant energy material. - The basic framework of the cell membrane was composed of a double-layer consisting of lysomes. Choline was an important component of animal cell membranes and was involved in the transport of fats in the blood. Therefore, it was correct to say that both lysomes and Choline were components of animal cell membranes. - The main reason for protein degeneration was the destruction of the spatial structure rather than the cleavage of the bond. Deoxy acids were connected to each other by the bond of the ester. Therefore, it was wrong to say that the high temperature degeneration of the protein was due to the cleavage of the bond, and the single chain was formed by the bond of the deoxy acids. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The new Jiangsu high school biology textbook had the following characteristics: ** I. Teaching Material Structure ** 1. ** Required and elective teaching material system ** - The compulsory teaching materials were divided into two volumes, volume one and volume two. The elective compulsory teaching materials were divided into three volumes, volume one, volume two and volume three. This structural arrangement reflected the layering and progression of high school biology knowledge. The compulsory textbook focused on the construction of basic knowledge in biology, which was something that all students needed to master, such as cell structure and function, biological inheritance and mutation, and other core knowledge sections. On the other hand, the elective compulsory textbooks expanded and deepened on the basis of compulsory knowledge. They were suitable for students who had further learning needs for biology. They might involve more in-depth content in the fields of biotechnology, biological evolution, and so on. 2. ** Division of content modules ** - Using cell-related knowledge as an example, the teaching materials introduced cells from the perspective of their variety and unity. For example, in the section on observing cells, he explained in detail how to use the microscope, including the steps of moving the object to the center of the field of view after finding the image with a low power microscope, then changing it to a high power microscope, and fine-tuning the fine focal spiral. This helped students to understand the cell structure in depth during experimental operation and theoretical study. At the same time, the textbook distinguished between prokaryonic cells and eukaryonic cells, explaining their structural characteristics, biological groups, etc. For example, eukaryota included plants, animals, fungi, etc. Prokaryota was mainly bacteria. This module division helped students clearly compare and understand the characteristics of different types of cells. ** 2. Knowledge content ** 1. ** Focus on basic concepts ** - The textbook emphasized the basic concepts of biology. For example, in the section on genetics, the explanation of related concepts was detailed. This was the basis for understanding the laws of biological genetics. For example, the definition of procaryotic cells and eukaryotic cells was distinguished according to the cell nucleus without a nuclear membrane. The fundamental differences in the structure and function of these two types of cells were clarified, which laid the foundation for the subsequent study of cell metabolism, cell division, and other knowledge. 2. ** The continuity and systematic nature of knowledge ** - From cells to individuals, from biological individuals to biological groups, knowledge was coherent and systematic. Taking biological evolution as an example, from the evolution of cells (the evolution of prokaryonic cells to eukaryonic cells), to the evolution of individual organisms under natural selection, to the variety and adaptability of biological groups, etc., they gradually deepened and guided students to establish a complete biological knowledge system. ** 3. Teaching and learning adaptability ** 1. ** Comply with teaching rules ** - The arrangement of the teaching content was in accordance with the teaching rules, from simple to deep, step by step. For example, when introducing the metabolism of living things, it would start from the input and output of substances in cells, then to the supply and utilization of energy in cells. This arrangement would help teachers gradually guide students to master relevant knowledge in the teaching process, and it would also be convenient for students to understand and absorb. 2. ** Promotion of students 'independent learning ** - The content of the teaching materials was rich, including a lot of inquiring content and thinking questions, which helped to promote students 'independent learning. For example, when explaining the cell structure, relevant discussion questions were set up, such as the relationship between the structural differences and functions of different cells, to stimulate students to think actively and cultivate students 'ability to explore. However, there might be some areas that needed to be reflected in the use of the teaching materials: 1. ** Difficulty of some content ** - For some regions or some students, some content might be more difficult. For example, the knowledge of genetics, especially the complicated calculation of genetic laws and the regulation of gene expression, might require teachers to spend more time explaining and tutoring to ensure that students could understand and master it. 2. ** Combination with practice ** - Under the background of biology emphasizing experiments and practical operations, the degree of integration of theoretical knowledge and practice in the textbooks needed to be further improved. Although there were some experiment-related introductions in the textbook, in actual teaching, more experimental cases or guidance for extra-cursory practical activities might be needed to allow students to better apply theoretical knowledge to practical operations and improve their biological discipline. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

I'll try my best to answer them.

The following is a summary of the high school biology information: 1. ** Life System and Cell ** - The structure of a living system was divided into cells, tissues, organs, systems, individuals, populations, communities, and ecological systems. The cell was the basic unit of a living organism's structure and function, and it was also the most basic living system on Earth. - The fundamental difference between a procaryotic cell and a eukaryotic cell was the existence of a nucleus with or without a nuclear membrane. Prokaryonic cells have no nuclear membrane and no chopsticks, such as bacteria such as E. Coli and cyanophagia; Eukaryotic cells have nuclear membrane and chopsticks, such as yeast and so on. Viruses have no cell structure, but they have DNA or DNA. - The founders of the cell theory were Schleiden and Schwann, who revealed the unity of cells and the unity of biological structures. 2. ** Elements and compounds in cells ** - The types of chemical elements that make up cells (biological world) are roughly the same as those in the organic world, but the contents are different. The major elements in the cells were C, H, O, N, P, S, K, Ka, and MG; the trace elements were iron, Mn, B, Mn, Mo, and copper; the main elements were C, H, O, N, P, and S; and the basic element was C. The most abundant element in the dry weight of the cells was C, and the most abundant element in the fresh weight was O. - The most abundant compound in the fresh weight of the organism was water, and the most abundant compound in the dry weight was protein. Reducting sugar (glucose, glucose, glucose) can react with Fehling's reagent to form a brick-red deposit; fat can be dyed orange by Sultan III (or red by Sultan IV); starch will turn blue when it comes into contact with iodines; and protein will react with biuret reagent to produce a purple reaction. - Polymers, protein, and nuclei were biological molecules, and their components were, in turn, monocosomes, followed by monocosomes, and then monocosomes, followed by monocosomes, and then monocosomes. 3. ** Cell structure and function ** - The operation steps of the optical microscope were to focus the light → observe with a low-power objective lens → move the center of the field of view (move it to the side) → observe with a high-power objective lens (you can only adjust the fine focal spiral, adjust the large aperture, and adjust the concave mirror). - Eukaryotic organelle had different functions and structures. For example, mitochondria and plastids had their own characteristics, and they had something in common. Prokaryotic cells and eukaryotic cells had cell membranes and plastids, which reflected unity. - There were specific changes in the DNA in the nucleus during mitosis, and there were different sources and destinations of ATP. 4. ** Photosynthesis and Breathing ** - The light reaction and dark reaction in photosynthesis could be compared. At the same time, the relationship between light energy utilization rate and photosynthesis efficiency should be clarified, as well as the relationship between external factors affecting photosynthesis and improving light energy utilization rate. - The process of cell breathing involved the metabolism of the three major nutrients in human and animal bodies. 5. ** Genetic Information ** - The carriers of genetic information were the nuclei, including DNA and R A. They played an important role in genetic variation and protein synthesis. There were differences in distribution, dyeing agents, chain number, bases, pentasugar, composition units, and representative organisms. - The basic unit of a protein was an aa. The R groups of different aa in the general structural formula were different. The aa formed a peptidic bond through dehydration condensation to form a peptidic chain. The protein's variety stemmed from the differences in the type, number, and order of aa, as well as the folding method of the peptidic chain. The protein had the functions of structural protein, catalyst, transportation carrier, information transmission, immunity, and so on. 6. ** Other aspects of living beings ** - In biological tissues, reducing sugar, fat, protein, and DNA could be identified, but sugar cane could not be used as the reducing sugar identification material. The Fehling reagent had to be prepared and used immediately (different from the biuret reagent). - In an ecosystem, the stability of resistance and the stability of resilience were not absolutely inverse. There were special situations such as the Arctic tundra. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
