High school biology review compulsory 1
High school compulsory two biology knowledge points complete version
The answer to the compulsory textbook of biology in senior high school
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>

Biology compulsory, mind map of cell life course
The following is the general framework of the cell life process mind map: ** 1. Cell reproduction ** 1. cell growth - Cell size increases - The efficiency of substance exchange would change with the growth of cells. The larger the volume, the smaller the relative surface area, and the lower the efficiency of substance exchange. This limited the unlimited growth of cells. 2. cell division - mitosis - Cell cycle: It includes interphase (G1 phase-preparatory work such as protein synthesis, S phase- DNA replication, G2 phase-further preparation) and division phase (prophase-appearance of the nuclei, formation of the spindles, etc.; Metaphase-arrangement of the nuclei on the equator; anaphase-division of the nuclei, separation of the sister chromatids into the nuclei and migration to the poles; telophase-disappearance of the nuclei and the nuclei, reappearance of the nuclear membrane and the nuclei, etc.). - [Meaning: Maintain the stability of the genetic material of the parent-child generation.] - Amitosis: There are no changes in the spindle-like fibers and the nuclei of the nuclei, just like the division of the frog's red blood cells. ** 2. Cell Division ** 1. [Concept: The process in which cells undergo changes in their form, structure, and function.] 2. characteristic - Durability: occurs throughout the life of an organism, but reaches its maximum during the embryonic stage. - [Stable: The differentiated cells will not return to their undifferentiated state.] 3. [Meaning: It can specialize the cells in multicellularized organisms and help improve the efficiency of various physiological functions.] ** 3. Cell aging ** 1. The characteristics of cell aging - The cell membrane's penetrability changed, and the material transport function decreased. - The water content in the cells decreased, the cells shrank, and their size became smaller. - The activity of many kinds of cellular zymes decreased. - Pigments in the cells would gradually accumulate as the cells aged. - The size of the nucleus increased, the nuclear membrane folded inward, the chromatin contracted, and the staining deepened. 2. The relationship between cell aging and individual aging: The cell aging of a single-celled organism is the aging of an individual; the cell aging of a multicellularized organism is not equal to the aging of an individual, but the aging process of an individual is also the aging process of the cells that make up an individual. ** 4. Cell Death ** 1. apoptosis - [Concept: The process of cells automatically ending their lives is a normal physiological phenomenon.] - [For example, the disappearance of the tail and the formation of fingers during the development of a human embryo.] - [Meaning: It plays a key role in the normal development of organisms, maintaining the stability of the internal environment, and resisting external interference.] 2. cell necrosis - [Concept: Under the influence of various adverse factors, cell damage and death caused by the damage or interruption of normal cell metabolism.] - [Characteristic: It is a passive, pathological death, such as tissue cell death caused by regional hemorrhage.] <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the concept of race in high school biology?
Race referred to the classification of human beings based on their physiological characteristics. This concept originated from the European colonial period and was used to distinguish between colonists and Europeans. Today, the concept of race is still used in human taxology, archaeology, genetics, and other fields, but the definition is slightly different in different disciplines. Races were mainly divided according to human physiological characteristics, such as skin color, hair texture, eye color, and so on. It should be noted that there was no reproductive isolation between different races. Humans were free to mate and produce healthy offspring. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
High school biology plant photosynthesis knowledge framework map
Photosynthesis was an important knowledge in high school biology. The following is the framework of its knowledge: ** 1. Concept ** 1. [Range: Green plants] 2. [Location: Phosphor.] 3. [Energy source: Light energy.] 4. [Materials: carbon dioxide and water.] 5. [Production: Energy-storing organic matter and oxygen.] ** 2. The process ** 1. Light reaction stage - [Location: On the thylakoid membrane of the plastids.] - material changes - Photolyzation of water: Water is decomposed into the reduced form of hydrogen and oxygen under light. - The synthesis of ATP-binding reagents: AAD and Phosphorous Acid synthesize ATP-binding reagents. - Energy change: The conversion of light energy into chemical energy in the form of bound bound 2. Dark Reaction Stage (Calvin Cycle) - [Location: Protoplasts stroma.] - material changes - The fixing of carbon dioxide: 1-molecular five-carbon compound and carbon dioxide form 2-molecular three-carbon compound. - The reduction of three-carbon compounds: When two molecules of three-carbon compounds are supplied with energy by ATP-and hydrogen by ADMPH, part of them will be reduced to form five-carbon compounds, and the other part will form organic substances such as sugar. - Energy change: The chemical energy in the molecules of ATPs and ADPs is converted into the chemical energy in organic matter. ** 3. Impact factors ** 1. internal factor - Plant species (Different plants have different photosynthesis abilities, such as C3 plants and C4 plants). - Leaf growth condition (such as leaf age, content of photosynthesis, etc.) 2. external factor - Light intensity: Affects the light reaction stage. Within a certain range, the increase in light intensity will increase the rate of photosynthesis. When it reaches the light saturation point, the increase in light intensity will no longer increase the rate of photosynthesis. - [Temperatures: By affecting the activity of the microorganisms, it affects photosynthesis. Different plants have different optimal temperatures for photosynthesis.] - [Concentration of carbon dioxide: Affects the dark reaction stage. Within a certain range, the concentration of carbon dioxide increases, and the rate of photosynthesis increases. When it reaches the carbon dioxide saturation point, the concentration increases, and the rate of photosynthesis no longer increases.] - Water: Water is one of the raw materials for photosynthesis. A lack of water will cause the stomata to close, affecting the entry of carbon dioxide and thus affecting photosynthesis. ** 4. Experiment-related ** 1. Extraction and Separation of Pigments from Green Leaves - extracting the coloring matter: dissolving the coloring matter with absolute alcohol. - Separation of Pigments: Separation of Pigments by using a separation solution according to the different dissolutes of different Pigments in the separation solution. The Pigments with high dissolutes will spread quickly on the filter paper (such as beta-Carotenin), and the Pigments with low dissolutes will spread slowly (such as Chlorella b). 2. Research on the conditions and products of photosynthesis (such as the use of radioactive labels to investigate the source of oxygen in photosynthesis). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
