The following are some of the experiments required for high school biology: 1. * * Observe the distribution of DNA and DNA in cells ** - * * Principle **: DNA is green, while DNA is red. Eukaryotic DNA was mainly distributed in the nucleus, while mitochondria and plastids contained a small amount of DNA. - * * Material selection **: oral cells or onion inner skin cells (colorless to prevent color interference). - * * Reagents and effects **: 0.9% NaCl-solution to maintain the normal cell form; 8% sulfuric acid to change the cell membrane penetration, so that DNA and protein can be separated for staining; mixed with the methyla-green pyronine dye solution. - * * Note **: Wash the cells slowly to prevent them from being washed away. - * * Results **: The nucleus is green, and the plasma is red. 2. * * Material Identification ** - * * Detection of reducing sugar ** - * * Principle **: reducing sugar + Fehling reagent → brick-red precipitations. - * * Material selection **: White or almost white materials with high reducing sugar content, such as apples, pears, and white radishes. Green leaves, watermelons, blood, potatoes (containing starch), sugar cane, and beets (containing sugar) cannot be used. - * * Reagents **: Ferlin's Reagents (Solution A: 0.1g/ml of NaOx solution, Solution B: 0.05g/ml of CuSO4 solution). - * * Steps **: Take 2 ml of sample solution and put it in a test tube. Add 1 ml of Fehling's reagent (mix the solution A and B evenly before adding). Heat it in a water bath for about 2 minutes and observe the color change (white → light blue → brick red). - * * Simulated urine sugar test **: Take the urine of normal people and patients with diabetes, and use Fehling's reagent (heated in a water bath), Bancroft's reagent, or urine sugar test paper to test. The urine of patients with diabetes contains reducing sugar and has brick-red deposits, while the urine of normal people does not contain reducing sugar or deposits. - * * Fat Detection ** - * * Principle **: Fat + Sultan III → orange; Fat + Sultan IV → red. - [Material Selection: Tissues with high fat content, such as peanut cotyledon.] - * * Steps **: Make the slices (the thinner the better). Drop 2 - 3 drops of Su Dan III dye solution on the peanut slices for 2 - 3 minutes, then suck off the dye solution. Drop 50% alcohol to wash off the floating color, then suck off the excess alcohol. Drop 1 - 2 drops of water on the slices, cover them with a cover glass, and perform microscopic examination (observe the fat particles dyed orange under low to high magnification). - * * Detection of protein ** - * * Principle **: protein + biuret reagent → purple reaction. - * * Reagents **: Biuret reagent (solution A: 0.1 g/ml of a solution of NaOx, solution B: 0.01 g/ml of a solution of CuSO4). - * * Steps **: Add 2 ml of sample solution to the test tube, add 1 ml of biuret reagent A, and shake it up. Add 4 drops of solution B, shake it up, and observe the color change. 3. * * Observing the flow of the plastids and the plasma ** - * * Materials **: Fresh moss leaves, black algae leaves or spinach leaves, and temporary slices of oral cells. - * * Principle **: Under the microscope, the plastids are green, spherical or oval. 4.

Here are some tips for learning photography: ** 1. Equipment ** 1. There was no need to master many complicated functions for taking photos with a mobile phone. In terms of camera settings, the "Aperture priority" mode had a high probability of being used, about 80%, mainly used to control the depth of field; the "Shutter priority" mode had a probability of about 15%, suitable for dynamic subject shooting control; the manual mode had a probability of only 5%, which was used when the focus could not be accurately focused. 2. It was important to understand the characteristics of different lenses. For example, the characteristics of a wide-angle lens affected the shooting effect. It should be used reasonably according to the needs. ** 2. Theoretic basis ** Every subject had a theoretical basis, and photography was no exception. It was necessary to study photography theory in depth. This would help to understand photography from the principle and provide guidance for practice. ** 3. Light usage ** 1. When shooting outdoors, the light angles in the morning and evening were the best, and the light quality was the softest. It was easier to take good photos at this time, but at the same time, you had to pay attention to ensure that the subject received perfect light. 2. In different scenes, such as wide-angle shooting, the use of light could not be ignored. ** 4. In terms of composition ** 1. A photo usually involved five main elements: the main body, the accompanying body, the environment, the prospect, and the background. 2. You can use a variety of composition methods, such as diagonal composition, triangular composition, etc. You can also try to take a full-body composition. At the same time, he had to pay attention to the composition of the picture and the guidance of the lines. 3. During the shooting process, you should pay attention to avoid debris, avoid cutting off the main body (such as people, objects, etc.), make reasonable use of the elements in the picture (such as the fence to reflect the sense of depth), and choose the correct focus point. 4. Try some special composition techniques, such as staggering the composition, capturing a picture-in-picture effect, and using elements such as windows to enrich the picture. ** 5. Other Points of Shooting ** 1. There were a lot of important points to pay attention to when it came to landscape photography. For example, you have to run hard to find a suitable shooting spot for a big scene; The light is better in the morning and evening, but the light is not good at noon; You should pay attention to the atmosphere of the wonder, and don't let go of the opportunity to shoot in rainy and foggy weather; You can also bring a camera when the weather is bad, and it may clear up in the evening; When using the big bottom plus slow film, the tripod shutter release, the zoom lens should be fixed as much as possible; Take off the protective mirror and put on the hood, the tripod should be locked tightly, and the mirror should be pre-locked; The scenery is gray, white plus black minus; During long exposure, measure the light frequently and pack a few photos up and down; Negative film should be slightly reduced, positive film can be slightly reduced; Wide-angle focus on the theme, telephoto compression scene; Small aperture depth of field is large, full open can paste the background; For flower shooting, use side backlighting, slow door to show dynamic; Stream is suitable for long exposure; Look for side light when seeing mountains, and shoot reflection when seeing water; Focus on the theme, level should be flat; Polarizer to remove reflection, gradual mirror to flatten contrast; When the contrast is too large, use black card; Long exposure should avoid car lights, rock wet shooting effect is good, etc. 2. In scenes such as portraits, one had to pay attention to the presentation of the character in the picture to avoid the character being cut off. The focus should be accurate (for example, the character corresponding to the eye-catching element should be focused accurately), and the messy elements in the picture should be avoided to interfere with the main body (for example, the interference elements on the ground should be avoided in crowd shooting). 3. Post-processing was also an indispensable part of photography. When shooting, one had to consider the possibility of post-production. For example, equipment with high enough resolution could be cropped later. If the resolution was not high enough, one had to pay attention to avoid the problem of image blurring that might be caused by post-production. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

First of all, if it was a fixed-focus half-frame lens, the focal length could not be changed. For a half-frame zoom lens, there was usually a ring-shaped adjustment device on the lens, namely the zoom ring. The focal length could be changed by rotating the zoom ring. In addition, if the camera lens has an automatic focal length adjustment function (some cameras have built-in intelligent algorithms), the camera can automatically adjust the focal length according to the shooting scene and the subject under the condition that the camera is in the correct shooting mode (such as automatic mode or smart mode). However, it should be noted that when the light is insufficient or the subject is moving too fast, it may affect the effect of automatic adjustment. If the automatic adjustment effect is not good, you can switch to manual adjustment mode to make fine adjustments. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
