Defy The Alpha(s)

Defy The Alpha(s)

Two centuries after the Great War, peace between humans and werewolves was finally achieved, or so everyone believes. Werewolves reign like gods, and humans remain blissfully unaware of their true place in the new world order. To maintain this fragile balance, each year, a handful of "lucky" humans are selected from various districts to attend Lunaris Academy, a prestigious institution that promises glory, status, and a chance to mingle with the elite. Those chosen are hailed as the lucky few, destined to marry powerful alphas and rise as luna. This year, Violet Purple is among the chosen, much to everyone's surprise. For an orphaned girl adopted by a disgraced prostitute, this is a golden ticket to a better life or so she's told. But Lunaris Academy isn’t the paradise it’s painted to be. Everything Violet and her fellow humans have been taught is a lie. Humans are far from equal; they're pawns in a much larger game. The academy is nothing but a gilded cage, and the students are lambs led to slaughter, playthings for the alphas to toy with in their ruthless games. To make matters worse, Violet catches the attention of the most dangerous players in this game, the Terror Four: the Alpha of the North, Alpha of the South, Alpha of the East, and Alpha of the West. Each one is more dangerous, more twisted, and more powerful than the last. But even among themselves, the alphas are divided, each with their own deadly ambitions. Yet, they all have their eyes on her. They expect Violet to play along, to fall in line like the others who worship at their feet, to break under their games. But Violet isn’t like the others. She refuses to bow. She’ll defy them all.

Défier Les Alpha(s)

Deux siècles après la Grande Guerre, la paix entre les humains et les loups-garous a finalement été atteinte, du moins tout le monde le croit. Les loups-garous règnent comme des dieux, et les humains restent dans une ignorance bienheureuse de leur véritable place dans le nouvel ordre mondial. Pour maintenir cet équilibre fragile, chaque année, une poignée d'humains "chanceux" sont sélectionnés dans divers districts pour assister à l'Académie Lunaris, une institution prestigieuse qui promet gloire, statut et une chance de côtoyer l'élite. Ceux qui sont choisis sont acclamés comme les quelques chanceux, destinés à épouser de puissants alphas et à s'élever en tant que luna. Cette année, Violet Purple est parmi les élus, à la surprise de tous. Pour une fille orpheline adoptée par une prostituée déshonorée, c'est un ticket en or pour une vie meilleure ou du moins c'est ce qu'on lui dit. Mais l'Académie Lunaris n'est pas le paradis qu'on décrit. Tout ce que Violet et ses camarades humains ont appris est un mensonge. Les humains sont loin d'être égaux ; ils sont des pions dans un jeu bien plus vaste. L'académie n'est rien de plus qu'une cage dorée, et les étudiants sont des agneaux menés à l'abattoir, des jouets pour les alphas dans leurs jeux impitoyables. Pour aggraver les choses, Violet attire l'attention des joueurs les plus dangereux dans ce jeu, les Quatre Terreurs : l'Alpha du Nord, l'Alpha du Sud, l'Alpha de l'Est et l'Alpha de l'Ouest. Chacun est plus dangereux, plus tordu et plus puissant que le précédent. Mais même entre eux, les alphas sont divisés, chacun poursuivant ses propres ambitions mortelles.

Analysis of the answers in cell biology textbooks

The 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. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

2020 National Biology League Answer Analysis

The following are some of the answers to the 2020 National Middle School Biology League questions: 1. In the traditional Trizol method for extracting the DNA, the following compounds were used: - The main components of Trizol were carbolic acid and guanidinium thionate. The carbolic acid could dissolve the protein and lyse the cells, releasing the protein/nuclear acid substances. Therefore, option A was correct. - The function of the chopstick was to help the separation of the water phase from the organic phase and to remove the compounds in the solution, so option B was correct. - Chloric acid didn't denature the DNA. Option C was wrong. - Chloric acid could remove some fat-dissolved impurities in the sample, such as oil and fat-dissolved colors. Option D was correct. Therefore, the answer to this question was an ABD. 2. Regarding the secondary structure of the green fluorescent protein, the green fluorescent protein was surrounded by a cylindrical fence: - The region where the larger R's (such as phe, pt, and ip) were concentrated would hinder the formation of the alpha helices, so option A was wrong. - The side chain of gly was too small, so its conformations were unstable and destroyed the formation of the alpha helices. Option B was wrong. - Phe can form a beta-sheet. Option C is correct. - The peptidic chain contains a protein that can form a beta-sheet. Option D is correct. Therefore, the answer to this question was CD. 3. The purification method of the Green Phosphorescence from the E. Coli lysed solution containing the Green Phosphorescence protein with the N-terminal 6*His tag: - According to the difference in the surface of the protein, the interaction between the protein and the surface of the medium was used to separate the protein. - Ion exchange separation of protein was based on the different charges of the protein under a certain pH. - Immobilized metal ion affinity column was a method for separating and purifying His-tag protein. This gel could specifically chelate with the His-tag protein, so that the protein was firmly attached to the gel through the metal ion. Other impurity protein could not be chelated with the metal ion because it did not carry the purification tag, so it could not be attached to the gel. - Gel-phase separation was a technique that used the molecular sieve effect of the particles with a multi-pore network structure to perform elution-separation based on the difference in the relative molecular mass of the components in the sample to be separated. Therefore, immobilized metal ion affinity column was the first choice for purification of the GFlp from the E. Coli lysed solution containing the GFlp protein with the N-terminal 6*His tag. The answer was C. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
