Analysis and answers to the questions in the novel1. Common questions:
1. What was the relationship between the beginning and the end of the novel?
2. It analyzed the effect of the structural arrangement of the beginning and end of the novel.
3. The beginning of the novel mentioned…and the end mentioned…what was the meaning behind this?
Second, the solution:
1. ** In terms of plot **
- To make the plot complete, from the whole process of the development of the novel's plot, the echo of the beginning and the end could connect the various parts of the story and form a complete plot chain. For example, setting up a suspense or plot element at the beginning and responding to it at the end would not make the plot feel lacking.
- Although it was mainly a structural setting, it could play a hint or guide role in the development of the plot. Some of the plot features at the beginning were echoed at the end, and the plot gradually progressed.
2. ** Character Creation **
- It could emphasize certain characteristics of the character or the direction of fate. For example, the beginning of the story described a certain state or character of the character, and the echo at the end could further strengthen this state or character, making the character more vivid.
- It reflected the growth or change of the character. If the character at the beginning was in an initial state, the ending would show the change of the character while echoing the beginning, which could shape the character's image more deeply.
3. ** In terms of thoughts, emotions, and theme expression **
- Deepen the theme. The beginning and the end of the echo often involve some elements related to the theme. Through this echo, the theme can be conveyed to the reader more deeply. For example, if the beginning hinted at a certain social phenomenon or human nature problem, the echo at the end would further explore the deeper meaning behind the phenomenon or problem, thus deepening the theme.
- To express emotions, the beginning and end of the sentence could enhance the effect of expressing emotions. If it was a positive emotion, the echo of the beginning and the end could make the emotion stronger, and if it was a negative emotion, it could make the reader feel it more deeply.
4. ** Writing structure **
- The structure was rigorous, and this was the most direct effect of the beginning and the end. The beginning and the end of the novel could make the overall structure of the novel more compact, making the reader feel that the novel was a well-constructed whole, rather than a loose combination of fragments.
3. Terminology:
1. In terms of the plot," the beginning and the end of the plot make the plot complete, avoid the plot being loose and abrupt, and the plot development is smooth and natural."
2. As for the character image," the beginning and the end of the character echo to strengthen the character's…characteristics, making the character image more three-dimensional and full, and the character's personality development or fate trajectory more clear."
3. In terms of the theme," the beginning and the end of the story deepen the theme, making the main theme of the novel more clear and profound, allowing the reader to understand the theme more thoroughly."
4. In terms of the structure of the writing," the beginning and the end echo each other to reflect the rigor of the novel's structure, making the article clear and organized."
Fourth, example analysis:
Imagine a novel that started with," The bell tower of a small town always chimes on the hour. The dull chimes seem to be telling an ancient story. Young Mary lived in this small town, and she was always curious about the secret behind the chimes." At the end, it was written," After Mary experienced all kinds of adventures, she returned to the town. The bell of the bell tower still rang on the hour. She now understood that behind the bell was the inheritance and persistence of the town's generations."
- In terms of the plot, the bell at the beginning of the story led to the story, and the bell at the end appeared again, making the plot complete. Mary's adventure story was wrapped in the element of the bell, and the plot developed naturally.
- In terms of character creation, Mary's curiosity at the beginning and her understanding at the end reflected her growth through the echo of the bell, making Mary's character image more full.
- In terms of theme, the bell chimes at the beginning and end deepened the theme of the town's cultural heritage, allowing readers to understand the cultural content of the town.
- In terms of structure, the bell chimes at the beginning and end made the novel's structure rigorous, giving people a sense of completeness and exquisiteness.

Questions and answers for the bioequivalent analysisBelow are some questions and answers related to the bioequivalent analysis:
** 1. Question on sample size and highly variable drugs **
1. ** Title *
In a bioequivalent test, a drug is known to be highly variable (assuming the coefficient of variation is greater than 30%), and the number of subjects required by the regulations is generally n. However, considering the requirements of statistics, is it enough to only meet the general requirements of the regulations? If not, what else should be done?
2. ** Answer **
When the drug is a highly variable drug, the number of subjects should not only meet the general requirements of the regulations, but also meet the requirements of statistics. In addition to the number of cases that meet the requirements of the regulations, some modifications in the trial design can be adopted, such as multi-dose studies, repeated measurement designs, or group sequence studies.
** 2. Question on the Log-transformation of Data **
1. ** Title *
In the bioequivalent evaluation, why is it generally recommended to carry out a log-transformation on the PK parameters such as the area under the drug concentration time curve before carrying out the bioequivalent evaluation?
2. ** Answer **
Generally, it is recommended to perform a bioequivalent evaluation after performing a log transformation on the PK parameters such as the ADC. There are two main reasons for this:
- Usually, the distribution of the peak concentration of the drug in blood and the concentration of the drug in the air were positively biased, and the variation was uneven. Log-transformation could improve the bias of the distribution and reduce the difference between the variations.
- The parameters of the drug were analyzed in the original measurement scale system. The effect of the experimental subject was not additivity, and the data after the log transformation could be processed by the addition model, which was of great significance in the statistics test. After the log transformation, it was more reliable and effective to use the analysis of variation and two-sided t-test to analyze the PK parameters. However, it should be noted that the sample size is limited in a bioequivalent study. Even if a logistic transformation is used, it cannot fundamentally make a reliable conclusion on whether a set of data conforms to the normal distribution.
** III. Questions on the relationship between analysis of variation and two-sided t-test **
1. ** Title *
The relationship between the analysis of variation and the two one-sided t-test in the bioequivalent test was briefly described.
2. ** Answer **
The analysis of variation and the two one-sided t-test were independent and related tests:
- Independent aspects: The two tests are two different tests, and the test hypothesis and conclusions are different. The test of variation was a difference test. The set invalid hypothesis was that there was no difference between the two drugs. The test method was yes or no. When P < 0.05, the difference between the two drugs was considered to be significant, but it was not necessarily not equivalent. When P>0.05, the difference between the two drugs was considered to be significant, but it was not necessarily equivalent. The two-sided t-test was a test for the equality of the two drugs. The invalid hypothesis was that the two drugs were not equivalent, and the test drug was outside a certain range of the reference drug. When P < 0.05, it meant that the test drug did not exceed the specified upper and lower limits of the reference drug, and the two drugs could be considered equivalent.
- Interrelated aspects:
- For a cross-over design, it was important to assume that there was no residual effect between cycles in order to accurately explain the results of the analysis of the equivalent. To determine whether there was a residual effect in the two cycles was a prerequisite for the two-sided t-test. Simply using a t-test was not appropriate. This approach ignored the possible residual effects (in the study of biochemistry, the residual effect was usually caused by the inappropriate length of the disinfection period). If there were residual effects that were not taken into account in the test, the analysis would be insensitive.
- In the bioequivalent experiment, the analysis of variation can indicate the source of error. The standard error of the test of the cross-over experiment is based on the mean square error in the analysis of variation of the cross-over experiment.

Analysis of the answers in cell biology textbooksThe following is an explanation of the concepts related to cell biology:
** 1. Basic Concepts of Cell **
1. ** Understanding that cells are the basic unit of life activities **
- From a structural point of view, all organisms were made up of cells, and cells were the foundation for constructing organisms.
- The cells had an independent and orderly self-controlled metabolism system. They were the executors of metabolism and function. The cell was also the foundation for the growth and development of an organism. It was also the basic unit of inheritance and had genetic omnipotency. Without cells, there would be no complete life. The cells themselves were a multi-layered, non-linear, and complex structural system. They were also a complex combination of substance (structure), energy, and information processes. They had a high degree of order, self-assembly, and self-organization.
2. ** The reason for the existence of the smallest and simplest form of cells **
- It could grow on a medium and had a typical cell membrane.
- Its genetic information was carried by a circular double-stranded DNA. The messenger acid could combine with the Ribosome to form a polysome to guide the synthesis of the protein. It split into two and multiplied. Its size was only one-tenth of that of bacteria, and it could also parasitize and reproduce in the cell.
3. ** The understanding of viruses as non-cellular life forms and the difference and relationship between viruses and cells **
- A virus was composed of a core of a single DNA or R A and a shell of a protein. It was the smallest and simplest organism. There were also special forms such as virus-like viruses that were composed only of infectious R A and prions that were composed only of infectious protein. Although viruses had the basic characteristics of replication and inheritance, they lacked the structure of cells and were incomplete life forms. Its main life activities could only be displayed inside the cells. It replicated and proliferated inside the host cells. It did not have an independent metabolism and energy conversion system. It had to rely on the host cells 'structure, raw materials, energy, and digestive system to proliferate. It was a complete parasite.
- Compared to cells, viruses were very small and had a very simple structure. Their genetic carriers were diverse and completely parasitic. They proliferated by replicating and assembling.
** 2. Concepts related to cell classification **
1. ** Evolutionary similarities and differences between prokaryonic cells, archaeokaryotic cells, and eukaryonic cells **(The reference materials did not provide a complete analysis, from the perspective of general knowledge)
- The similarities were that they all had genetic material, which was related to the basic functions of life, such as the ability to synthesize certain substances.
- The difference:
- Procaryotes did not have a nucleus covered by a nuclear membrane. Their DNA was exposed, and they had the characteristics of space-time continuity in DNA replication, replication, and translation.
- Eukaryotic cells had a nucleus that was covered by a nuclear membrane, and its expression and regulation were much more complicated. It could be regulated at various levels, such as pre-transcribed level, transcribed level, post-transcribed level, translated level, and post-translated level.
- Archaeus cells had unique properties in some aspects. In terms of evolutionary relationship, they were in a special position between procaryotic cells and eukaryotic cells. For example, they had some characteristics different from procaryotic cells in terms of gene replication and translation.
** 3. Concepts related to cell structure and function **
1. ** Concepts related to the composition of cells **
- The most basic biological small molecules that make up cells are the nuclei, the acids, the fatty acid, and the sugar. They form important biological molecules such as the nuclei, the protein, the fat, and the glycan.
2. ** Concepts related to cell sub-discipline (Experimental Biology)**
- The main branches of cell science that were formed by the combination of cell science and other biological sciences were cell genetics, cell biology, and cell chemistry.
3. ** Concepts related to cell membrane structure **
- Phospholiptides on the biological membrane mainly include Phosphatidylcholin (Phosphatidyl Choline), Phosphatidyl Serine, Phosphatidylinositol, Phosphatidylethanolamin, and Sphingomyelin. The membrane protein could be divided into membrane intrinsic protein (integral membrane protein) and membrane peripheral protein (membrane outer protein). The basic characteristics of biological membranes were mobility and unsymmetrical. The main ways of binding between intrinsic protein and membrane were the interaction of water affinity, ion bond, and the interaction of the two bonds.
4. ** Concepts related to cell connection **
- Cell connections could be divided into closed connections, anchored connections, and communication connections. The main ways of anchor connection were desmosome, hemidesmosome, and the adhension zone and focal adhension. The desmosome was connected to the intermediate fibers in the skeletal system, while the adhension zone was connected to the microfibers (actins). The main ways of communication were gap junction, plasmodesmata, and chemical bond.
5. ** Concepts related to the extra-cellular matrix **
- The basic components of the matrix were mainly composed of protein, elastins, glycan, laminins, fibronectins, etc. The main components of plant cell walls were Celluloses, Hemicelluloses, Flucoids, Expansins, and Proglycans.
6. ** Concepts related to cell surface specialized structures **
- The specialized structures formed on the surface of the cell included membrane skeleton, microvils, flagella, cilia, and deformed feet.
7. ** Concepts related to the transport of substances across membranes **
- The main pathways of material transport across the membrane were passive transport, active transport, as well as the effects of engulfment and exomyosis. Passive transport could be divided into simple and assisted diffusing. The latter required specific membrane transport protein (carrier protein and channel protein) to complete the transport of substances across the membrane. According to the energy source, active transport could be divided into ATP-directly powered transport, ATP-indirectly powered transport, and optical driven active transport. Co-transport belonged to the active transport type. According to the relationship between the direction of material transport and the direction of ion transfer along the electrochemistry, it could be divided into co-transport (co-transport) and reverse transport. For example, in the sodium-potassium pump, every atom of ATP-consumed could transport 3 Na ions and 2 K ions. The sodium-potassium pump and the calcium pump were both multi-spanning membrane protein with ATP-ase activity. In eukaryotic cells, there were three types of photon pump: P-type photon pump, V-type photon pump, and H + -ATPases. The transport of large molecules across the membrane was completed by transcytosis and exomyosis. According to the size of the vesicle and the substances that were swallowed, transcytosis could be divided into transcytosis and engulfment.
** 4. Concepts related to cell observation technology **
1. ** Microscope resolution concept **
- The resolution referred to the smallest distance between two particles that the microscope could distinguish.
2. ** Concepts related to electron microscope **
- The electron microscope was mainly divided into two types: transmission electron microscope and scanning electron microscope. The commonly used electron microscope techniques in biology included ultra-thin section technique, negative staining technique, freeze-engraving technique, and so on.
