Tomorrow is the biological experiment, but there are two experiments that will not be

I haven't dissected chicken wings, only mice, fish, frogs and the like, but if you cut **, you should use scissors to make a small opening in a certain part, and then use the second tool on the left in the picture (my dissection tool bag, but I'm abroad, I don't know your one is different) The thin end of the second tool on the left reaches reaches into the small mouth but don't go through the muscles, so that the muscles and ** are separated, and then cut along the grooves of the tool with scissors.

If you want to load the film temporarily, remember to put one or two drops of water (or other solutions as required) after putting the sample on the slide, and then be careful, stick one side of the coverslip, and then slowly cover it all, it will not produce bubbles. If bubbles develop, remove the coverslip and re-cap.

If you don't beat the egg, it won't break, (just kidding, I don't know how to make it) <>

1.There is also a ??? for dissecting chicken wings

2.To cover the coverslip, first drop a drop of water on the slide, use tweezers to pick up one side of the coverslip, and stick the other side on the slide, the tweezers slowly put the slide down, pay attention to the bubbles in this process, lift up the bubbles and slowly put them down again, be careful, until the whole slide should go down, it is not difficult, rely on care.

3.For staining, use a pipette to drop a drop of dye on one side of the coverslip, and the other side with the edge of the filter paper, using the capillary principle, suck the dye from one side to the other side to complete the staining, this is also very simple.

4.To observe the image, first put the entire slide on the microscope stage and clamp it. Then choose your objective lens, adjust the coarse collimation spiral after selection, pay attention not to press the fragments when adjusting, and when you see that it is almost clear, slowly adjust the coarse focus spiral until it is completely clear.

5.How do you not break eggs? Are you a Shenma experiment? And this kind of problem? Be careful yourself, don't you fall to the ground and it won't break?

Summary. According to the situation you described, if you are a student, the biology test may have a certain impact on your academic and academic performance, especially if the course is compulsory or related to your major. Failing the exam may result in you not being able to earn credit, which in turn will affect your graduation requirements and schedule.

In addition, if you plan to enter certain fields of research or further your studies, failing the biology laboratory exam may have a certain impact on your application and admission. If you are not a student, failing the biology lab exam may have an impact on your career. If your career requires skills and knowledge in biological experiments, failing the exam may affect your career development and advancement opportunities.

In short, the biology test may have an impact on your studies and career, so try your best to prepare for the exam and get a good score so that you can better achieve your academic and career goals.

What if it's Fujian.

Hello dear, according to the situation you described, if you are a student in Fujian, failing to pass the biology laboratory exam may have a definite impact on your academic performance and grades, especially if the course is compulsory or related to your major. Failing to pass the exam may affect your credits and graduation requirements. In addition, in the admission rules of the college entrance examination in Fujian Province, the results of the college entrance examination and the results of the selected subjects are very important reference factors.

If you fail to score well in the Biology Lab Exam, it may affect your overall score and optional subject scores in the Gaokao, which may affect your Gaokao admission results. Therefore, for students in Fujian, the importance of the Fushi Biology Experimental Exam is similar to that of students in other regions, and it is also necessary to work hard to prepare and get good grades.

Summary. Hello dear, happy to answer your <>

There is a sheet for the biology experiment exam, and you need to bring a sheet for the biology experiment exam. Because experimental operations require records and materials, the list can easily record the experimental process and results, and can also help the experimenter avoid missing important steps in the experimental operation. Finally, thank you for your patience yo <>

Is there a lab sheet for the <> Biology Lab Exam?

Hello dear, happy to answer your <>

There is an experiment sheet for the biology real banquet section test exam, and a list needs to be brought for the life service reputation test exam. Because experimental operations require records and materials, the list can easily record the experimental process and results, and can also help the experimenter avoid missing important steps in the experimental operation. Finally, thank you for your patience yo <>

Can I bring it to each regional exam?

Look at the requirements in your area.

What region are you from?

Guang'an, Sichuan. You don't need to bring it to this area.

Whether you don't need to bring it or you can't bring it.

I can't bring it. Hmmm.

Dear, the relevant expansion information is <> here

Biological experiments refer to the process of purposefully observing and studying the structure of organisms and life activities phenomena that are not easy to observe under normal circumstances by using certain instruments, materials and drugs under specific environmental conditions, through scientific methods. Biology is a natural science based on experiments. <>

<> biological experiments can not only help students understand the concepts and laws of biology and truly learn the basic knowledge of biology, but also help inspire students to think positively, train them in scientific methods, and cultivate students' scientific quality. Biological experiments are an important part of the examination over the years, and with the continuous development of the high school entrance examination, hands-on experiments will become the development trend of the high school entrance examination. <>

Experimental principle: Starch and sucrose are both non-reducing sugars, which can be hydrolyzed into reducing sugars under the catalysis of enzymes, and the reducing sugars can undergo redox reactions with Feilin reagent to generate brick-red precipitates.

The experimental procedures and results are shown in the figure below, I hope it will be helpful to you.

It doesn't have a temperature treatment in this answer at all, how can it come to that conclusion, so this answer should be wrong.

I think that if we want to test that idea, we should take two sets of materials treated at different temperatures, such as 50 and 70 degrees Celsius, and then add substance A to the sections treated at a lower temperature (50 degrees Celsius), and add the same amount of water to the one treated at 70 degrees Celsius, and then measure the absorbance value of the leachate. This idea can be demonstrated if the absorbance value of the leachate treated at 50 degrees Celsius is close to that of the 70 degrees Celsius treatment (which should be much smaller under normal circumstances), combined with the known condition of substance A to promote the activity of the carrier on the cell membrane.
