The solution to the copyright problem was as follows: 1. Clear ownership of copyright: Through contracts, agreements, etc., the rights and obligations of all parties to the work are clearly defined. This is the basis for resolving copyright issues and can avoid subsequent disputes. 2. Increase awareness of copyright protection: Creators should register their copyrights in a timely manner and obtain copyright certificates recognized by the law. When using other people's works, they must obtain legal authorization to avoid copyright infringement. According to the copyright law, without the permission of the copyright owner, copying, distributing, performing, screening, broadcasting, compiling, and spreading the work to the public through the information network are acts of copyright violation. 3. How to resolve copyright disputes: - Negotiate: The parties involved negotiate and reconcile. - mediation: entrust a third party, such as the copyright bureau, copyright protection association, law firm, natural person, etc., to mediate. - Arbitration: submit to an arbitration institution for arbitration according to a written arbitration agreement. - Lawsuit: Directly file a lawsuit in the people's court. Under certain circumstances, such as editing from media: 1. You can use the authorized film and television works in the Watermelon Video Projection Hall for editing. This way, the edited works will be easier to pass the platform's review and receive recommendations. 2. He performed a deep second editing, mixing multiple film and television clips according to his own ideas to form a new theme video. At the same time, he was equipped with rich editing elements. 3. Pay attention to the copyright of the video before posting it, and make clear which ones can be used for free to avoid copyright infringement. You can also download the content from some authorized material websites (such as videoezy, Wedistill, FootageCrate, Monzoom, and other foreign websites). If it involves the copyright of the movie, you can apply to iQiyi, Youku, and other platforms.

1. ** Solution to the calculation of photosynthesis rate ** - When it came to the calculation of photosynthesis rate, the relationship between actual (true) photosynthesis rate, net (apparent) photosynthesis rate, and respiratory rate should be made clear. The actual photosynthesizing rate = net photosynthesizing rate + respiratory rate. - For example, when calculating the relevant amount of carbon dioxide, the actual assimilation of carbon dioxide = the actual absorption of carbon dioxide + the release of carbon dioxide. - For the calculation of oxygen, the actual O2 release from photosynthesis = the actual (apparent photosynthesis) O2 release + the absorption of oxygen from the respiratory rate. - When calculating the amount of sugar, the net production of sugar from photosynthesis = the actual production of sugar from photosynthesis minus the consumption of sugar from respiration; the net organic matter (accumulation)= the actual production of organic matter (photosynthesis) minus the consumption of organic matter (respiration). - When calculating the combination of the two types of breathing, one must first determine the conditions of the breathing type. Under the condition of sufficient oxygen, the amount of oxygen absorbed and the amount of CO2 released were equal. Under the condition of absolute oxygen deficiency, only the oxygen deficiency could be carried out. Under the condition of oxygen deficiency, both oxygen and oxygen deficiency could be carried out. The amount of oxygen absorbed and the amount of CO2 released were not necessarily equal. When solving the problem, one must first write and balance the reaction formula correctly. Secondly, one must distinguish the source of the CO2 and then calculate it (how much CO2 is produced by both the oxygen and the oxygen breathing). 2. ** Solution to the concept map or relationship problems of photosynthesis and respiration ** - It should be clear that the raw materials of photosynthesis were carbon dioxide and water, the products were organic matter and oxygen, and the location was the plastids. Respocation was a process in which cells used oxygen to decompose organic matter into carbon dioxide and water, and released the energy stored in organic matter for life activities. The location was mainly in the mitochondria. The two were independent and dependent on each other. Photosynthesis provided the material basis for respiration, and respiration provided the raw materials for photosynthesis. - For example, when filling in the blanks in the concept map, he would fill in the blanks based on his understanding of the concepts, raw materials, products, locations, and so on. 3. ** About the solution to the biology problem of photosynthesis ** - When measuring the breathing rate: - In terms of equipment, the commonly used equipment was to use the solution of <anno data-annotation-id ="00000440 - 4000 - 4000 - 8000 - 8000 - 90000000000"></anno> to absorb </anno></anno> and observe the amount of </anno></anno> absorbed in the unit time or the change in the pressure in the container (such as the movement of water droplets in the scale tube) to indicate the breathing rate. - Pay attention to error correction. If the experimental material is a green plant, the entire device should be shielded from light, otherwise the photosynthesis rate will interfere with the detection of the respiratory rate. If the seeds are selected as experimental materials, the existence of microorganisms must be considered to interfere with the detection of the experiment. Therefore, the device and the tested seeds should be disinfected. In order to avoid errors caused by physical factors such as air pressure and temperature during the experiment, a control experiment should be set up. The tested biological materials should be deactivated (such as cooking the seeds), and other conditions should remain unchanged. - When measuring the photosynthesis rate: - Using the solution of NaOx to absorb the CO2 in the container, the cell's respiratory rate could be measured by the change of oxygen. Using the decomposition of NaHCO3 to produce carbon dioxide to ensure the stability of carbon dioxide in the container, the increase of oxygen in the container could be measured to obtain the plant's net photosynthesis rate. - When analyzing the experiment results: - For example, in the experiment of "Green leaves produce organic matter under light", the purpose of placing the plant in the dark for a day and night was to deplete the original starch in the leaves; covering the leaves with black paper was to set up a control experiment; and the leaves were heated in alcohol with water to dissolve the photosynthesis in the alcohol. Then, according to the color development of the different treatment groups (such as the shaded and non-shaded parts) after dripping the solution, the conditions of photosynthesis (such as light), products (starch), etc. were analyzed. For the comparison of multiple sets of experiments (such as different leaf treatments), the impact of each experimental variable on photosynthesis should be analyzed, such as the impact of a lack of a certain raw material (such as carbon dioxide) on the production of photosynthesis products. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The solution to the diagonally symmetrical determinan-type question was as follows: 1. The definition method was applicable when there were more 0s in the determinant. 2. Spread out order reduction by row (column): If a row (column) has special circumstances that can be used, solve it by expanding to achieve order reduction. 3. Using the seven basic properties to transform into triangular matrixes, one could get as many zero elements as possible by adding and deducting different rows and columns, and then use the matrixes to expand by rows (columns). 4. According to the properties of the determinant, it can be directly solved: For a diagonal symmetrical determinant, the product of the elements on the diagonal can be used to determine the value of the determinant. For example, for a 3rd order determinant: |abc| |def| |ghi| Where a, e, and i are on the diagonal, the value of the determinant is a * e * i. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
