The following are some examples of questions and answers related to junior high school biology research: * * I. Research on the effects of alcoholism on the human body ** 1. [Question: How does alcohol affect the nervous system?] - Alcohol can seriously damage a person's nervous system. The central nervous system includes the brain and spinal cord, and the brain is composed of the cerebrum, cerebrum, and brainstem. When drinking too much, alcohol would poison the cerebrum, causing damage to the cerebrum's ability to maintain body balance and accurate coordination of movements, resulting in instability in walking. Alcohol would poison the language center of the cerebral hemisphere, causing speech to be unclear. It would poison the visual center, causing hallucinations. In severe cases, the entire nerve center would be poisoned, causing confusion, loss of consciousness, and lethargy. For example, when studying the effects of alcohol on the driver, there might be a loss of coordination and accuracy of hand and foot movements, which might be caused by alcohol anesthetizing the cerebrum. 2. [Question: How does alcohol affect the heart rate of the water fleas?] - * * Explanation of the answer **: Assuming that the alcohol concentration has an effect on the heart rate of the water fleas, the experimental variable is the alcohol concentration. In the experiment, as the volume fraction of alcohol increased, for example, when the volume fraction of alcohol was 5%, 10%, 15%, and 20%, the corresponding heart rate of the Daphnia was 24, 21, 17, and 0 (death) respectively, indicating that the heart rate of the Daphnia gradually decreased until death. This also meant that alcohol abuse would cause the central nervous system to be overly excited, causing alcoholism. Alcohol abuse in pregnant women could also cause fetal development disorder or low intelligence, and even cause fetal deformities. At the same time, in order to show the effect of alcohol, a control group with only water and no alcohol should be added to the experimental design. * * 2. Research on the biological effects of smoking ** 1. [Question: What is the effect of smoking on the health of mice?] - * * Explanation of the answer **: In the experiment to explore the effects of smoking on the health of mice, if the number of mice in each group is too small (such as only a few), the result is too accidental and not scientific and convincing. After the improvement, if the mice in Group A were normal, the mice in Group B would have bloodshot eyes, red and swollen eyes, abnormal activities, and finally spasm and shock after being exposed to smoking-related substances (simulated smoking environment, etc.). Through comparison, it could be concluded that smoking was harmful to health. 2. [Question: Which systems do the harmful substances produced by smoking harm?] - There are more than 40 kinds of cancer-causing substances in the smoke produced by smoking, as well as more than ten kinds of substances that promote the development of cancer. Among them, the most harmful ones are Nicotine, carbon dioxide, tar, and many other metal compounds. These toxic substances first entered the human body's respiratory system directly, causing respiratory diseases such as tracheitis, rheumatism, pneumonias, and lung cancer. Furthermore, not only did smoking endanger their own health, but it also seriously affected the health of others. It was more harmful to others than to themselves. * * 3. Exploration on the application of fermentation in biology ** 1. [Question: In the process of producing fuel alcohol from corn stalks, what kind of bacteria is needed to produce alcohol from sugar liquid?] - * * Explanation of the answer **: The fermentation of microorganisms plays an important role in food production and other aspects. In the general process of producing fuel alcohol from corn stalks, the bacteria needed for the stage from sugar liquid to alcohol is yeast. Yeast can decompose glucose to produce alcohol and carbon dioxide in the absence of oxygen. * * 4. Exploration on visual formation ** 1. [Question: When the light from the red light enters the eyeball to form an image, what is the order in which the light enters the eyeball?] - * * Explanation of the answer **: The order in which light enters the eyeball is: corneas, pupil, crystalline lens, vitreal body, retina. The photosensory cells in the retina received the stimulation of the image and converted the image information into nerve impulses, which were then transmitted through the optical nerve to the visual center of the cerebral hemisphere to form vision. When a driver stopped at a red light, the cerebral hemisphere was involved in this process, which was a complex reflex. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

In theory, the Nikon D3500 didn't have any restrictions on the choice of lens when shooting scenery. However, considering the control of distortion during post-stitching, it was best to control the focal length of the lens to be above 50mm for panoramic shooting. Otherwise, there would be a large distortion at the beginning and end of the picture after stitching. In order to minimize the distortion of the panoramic film, it was recommended to use a medium telephoto lens for shooting. For example, a lens with a focal length of 70 - 200 was very suitable. If the starting point was to learn photography and get better image quality at a lower price, the Nikon D3500 was the right choice. It could be used with AF-P 18 - 55mm F3.5 - 5.6 VR + AF-P 70 - 300F4.5 - 6.3G ED dual-head camera for shooting. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
