The biological experiment operation exam had a variety of contents. The following were some common experimental operations: 1. ** Cell related experiments ** - ** Prepare and observe the onion scales and leaf inner skin cells. - The preparation work included filling in the school, name, exam number, materials and equipment. The equipment used included a microscope, gauze, iodination solution, a drip bottle filled with clean water, a single-sided blade, blotting paper, onion scale leaves, cover glasses, slide glasses, tweezers, waste gas buckets, rags, and so on. - The preparation process was to wipe (wipe the glass slide and cover glass with clean gauze), drip (drip 1 - 2 drops of water in the center of the glass slide), take (use a blade to draw a small square on the inner surface of the onion scale leaf and then tear a small piece with tweezers), spread (soak the torn inner surface into the water drop and flatten it with tweezers), cover (use tweezers to clamp the cover glass while touching the water drop first and then slowly put it down), dye (drip the solution of iodination on one side of the cover glass, and use blotting paper to absorb the solution of iodination on the other side to soak the entire specimen). - When observing, you have to take the mirror and place it (Hold the mirror wall with one hand, hold the mirror stand with the other, place it about 7 cm away from the edge of the experiment table and install the eyepieces and objective lens), light (Raise the lens barrel, turn the shifter so that the low-power objective lens is aimed at the light hole, maintain a distance of about 2 cm, aim the large aperture at the light hole, and see a bright circular field of view by turning the mirror), observe (Place the specimen slide on the stage and press it with a pressing plate, facing the center of the light hole. Turn the coarse focus screw to lower the lens to the specimen slide. Look at the objective lens from the side. Then turn the coarse focus screw to raise the lens to look for the object and adjust it to the center of the field of view). Finally, arrange the equipment.(Take off the glass slide, rinse it, wipe it, and put it back in its original place. Turn the shifter to tilt the objective lens to the sides, lower the lens to the lowest point, turn the mirror to place it vertically, wipe the objective lens, reset the experimental equipment, dispose of the onion scales, leaves, blotting paper, and other wastes, and fill in the experimental report.) - ** Observation of permanent smear of human blood **: It mainly uses a microscope and a permanent smear of human blood for observation. - ** Observing the mitotic slices of plant cells **: Through microscopic observation of slices, one can understand the related structure of mitosis of plant cells. 2. ** Seed-related experiments ** - ** Observe the structure of the seed **: - For the soaked kidney bean (soybean, broad bean, etc.) seeds and corn seeds, equipment such as magnifying glasses, blades, dissecting needles, dropper, petri dishes, and diluted iodination solution would be used. - The experiment process included observing the external shape and identifying the structure, such as cutting the corn seed vertically from the center. - ** Investigate whether light is the external condition for seed sprouting **: You need to set different lighting conditions to explore the relationship between seed sprouting and light. 3. ** Other experiments ** - ** Observing the structure of the leaf's abyssal skin **: Use a microscope, glass slide, cover glass, gauze, tweezers, dropper, blotting paper, blade, and other equipment, as well as fresh spinach or broad bean leaves, and other materials. Use clear water to carry out the experimental operation to observe the structure of the leaf's abyssal skin. - ** Observe the permanent section of the leaf cross-section **: Observe the permanent section of the leaf cross-section with the help of a microscope. - [Confirm that food contains energy: Use the assembled iron frame and its auxiliary structures, test tubes, thermometer, dissecting needle, alcohol lamp, match, peanut seeds, water, and other materials to carry out the experiment.] <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

A burning sensation in the throat and foreign body sensation could be caused by many reasons, and the severity varied according to the cause. If it was chronic sore throat, the treatment first needed to remove the cause, such as quitting smoking and drinking. Compound Borax Solution and Furacilin Solution can be used to gargle; Peppermint Throat Tablets, Watermelon Frost Buccal Tablets, Yiqing Granules, Jinsang Liyan Pills, Taileqi Buccal Tablets, etc. can also be taken by mouth. If it was the case of sore throat, it required oral administration of acid suppressors such as Omeprazol and other drugs to promote gastric and intestinal mobility such as mosapride dispersing tablets. In addition, it was necessary to take a light and soft diet with fewer meals. As for chronic allergic sinusinustralgia (which occurs after allergic patients come into contact with an allergic substance), it is necessary to effectively avoid contact with the allergic substance. Antihistamines such as loratadin and other steroids such as steroid can be taken by mouth, and local budeside suspension can also be used for treatment. Tumors in the throat could also cause similar symptoms, such as epiglottis, throat cancer, etc. These conditions were relatively serious and generally required surgery to remove them. After the surgery, chemotherapy drugs were used according to the specific condition. Patients with mental illnesses such as anxiety and depression may have a foreign body sensation in the throat. Medicines should be used according to different types of diseases, such as buspirone for anxiety and sertraline for depression. At the same time, psychotherapy could be combined. If such symptoms occur, it is recommended to seek medical advice to determine the cause before carrying out targeted treatment. The above-mentioned drugs should be used under the guidance of a doctor. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The main reasons for the decrease in the biological pool of the sewage plant were as follows: 1. ** Strong acid in the feed water **: If there is strong acid in the feed water, it will directly cause the pH of the feed water to decrease, and then the pH of the mixture will decrease. 2. ** Nitration reaction consumes basicity **: During the nitration process, as NH3 - N is converted into NO3 - N, a portion of the acidic content H will be produced, and this portion of the acidic content will consume a portion of basicity. Each gram of NH3 - N converted into NO3 - N consumed about 7.14g of alkalinity (calculated as CaC03). When the alkalinity in the sewage was insufficient and the total Kjeldahl nitrogen (TKN) load was high, the alkalinity in the sewage would be exhausted, causing the pH value in the mixed solution to drop below 7.0, resulting in the reduction or inhibition of the nitration rate. 3. ** Acid production in the biochemical reaction **: In the whole biochemical process, the stages of acidic digestion and hydrogen production and acetate-production will cause the water's pH to drop, and the residence time of these two stages is relatively short. 4. ** Comprehensive influence of factors such as nitrogen nitrogen, agitation, and organic matter concentration **: When the nitrogen nitrogen in the water is high, when the biochemical tank has a large amount of agitation, a long residence time, and a low concentration of organic matter, it will accelerate the nitration process, resulting in a decrease in the pH. However, in this case, the pH. 5. ** Anerobic fermentation in municipal sewage transmission pipeline **: The slight decrease in the pH value may be due to the anerobic fermentation in the municipal sewage transmission pipeline. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The so-called domestic violence in the name of "love" could not be considered true love. In cases of domestic violence, some domestic abusers might claim that they committed violence because of love, but this kind of behavior was essentially hurting and controlling others. For example, in the Ram case, her ex-husband, Tang Lu, used the pretense of love to inflict violence on Ram, which eventually led to a tragedy. This was actually to satisfy his own selfish desires, not true love. In many cases of domestic violence, the abuser may have cognitive bias. They don't respect their partner and ignore their partner's efforts and hard work. This kind of violence goes against the nature of love. True love should not include violence.
