Is the biological fluid bed the same as the biological filter? Why?
Biological Fluidized Beds and Biological Filers had the same function. They were both used for sewage purification. The biofilter was a biological treatment structure composed of gravel or plastic fillings. The sewage was purified by the gap contact between the microorganisms growing on the surface of the fillings. Biological Fluidized Bed is made of sand, activated carbon, coke and other particle materials as carriers, attached with a biological membrane, and the oxygen filled waste water flows from bottom to top at a certain rate, so that the carrier is in a fluidized state, thereby strengthening the contact time between the biological membrane and the sewage, allowing the biological membrane to fully contact with the sewage to degrade organic matter, thereby purifying the sewage. Although the working principles of the two were different, the ultimate goal was to purify sewage. Read more exciting novels for free
Fishing biological fluid
The fishing biological fluid was a type of addition to fishing bait. In terms of price, there were different price ranges. For example, there was a natural fish lure that sold for 43.92 to 48.80 yuan. There were also other products such as Cheng Yang's fish, Xiao Zhiqiang's bait, fishing, biological liquid, small medicine, explosive mouth, carp, scattered cannon, bubble ball, black pit carp bait, etc. The price of different formulas might be different. There were powder forms and liquid forms. Different products were targeted at different fish, such as carp. Its main function was to stimulate the fish to bite the hook and attract the fish by emitting a special smell or providing biological active substances. It was similar to the fragrance of plant bait that could stimulate the sense of smell and taste of fish. The fishy smell and squirming of biological bait attracted fish. The fishing biological fluid also increased the probability of fish being hooked from the perspective of fish senses. However, from the test results, it could be compared with the experiment. For example, four people sitting at four corners and leveling the water to fish for four eyes. The two people next to each other used or did not use the biological fluid. The two people on the opposite side also did the same. They tested the effect and ratio of the biological fluid by grabbing the dead end (the situation where the drag bar was blackened). However, some fishing biological fluids might not be effective. For example, the red worm fish feed did not attract fish in the test. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Introduction of Biological Fungus Fermenting Bed
The biological bacteria fermentation bed was a technology that utilized the fermentation of microorganisms. In terms of pig farming, it was an ecological pig farming method that integrated multi-disciplinary knowledge. It followed the principles of low cost, high output, and no pollution to build a virtuous cycle of ecological pig farming system. It could achieve no discharge, no pollution, no odor, and solve the environmental pollution problem of large-scale pig farms. The feeding density of the pigs varied according to the conditions of the fermentation bed and the season. The amount of feed was controlled to be about 80% of the normal amount, which was conducive to the pigs digging the ground. In the aspect of raising poultry, such as raising chicks, the use of biological fermentation beds could increase the survival rate and reduce the stench of the chicken coop, saving labor. The thickness of the fermentation bed was 10 - 20 cm, and a pack of "Enhanced Fermenting Bed Compound Fungus" could make a 15 - 20 square meter fermentation bed. First, mix the composite bacteria in the fermentation bed with 5 - 10 kg of corn flour, then mix it evenly with sawdust, pour an appropriate amount of water (make the sawdust moist), and then cover the film to ferment for 3 - 5 days. The small and medium chicken shop was 10 - 15 cm thick, and the medium and large chicken shop was 15 - 20 cm thick. The stocking density was 10 - 15 small and medium chickens per square meter, and 6 - 10 large and medium chickens weighing more than 2 jin (depending on the breed, the larger the size, the smaller the stocking density). The maintenance includes replenishing the bacteria every 3 - 6 months (each bag of compound bacteria in the fermentation bed is mixed with 5 - 10 kg of corn flour, then sprinkled on the surface of the fermentation bed and simply turned over. This operation is also carried out when the bacteria replenishment time is not up but the fermentation bed is smelly or cannot decompose chicken manure). When the fermentation bed descends more than 5 cm, sawdust is added and mixed. When the humidity of the fermentation bed is high, the rake is turned over. The biological bacteria fermentation bed was also a useful assistant for courtyard farming. With it, there was no need to clean up the chicken manure, and there was no smell of chicken manure. In addition, the biological fermentation bed could also be used to treat organic waste to produce organic fertilizer and biological gas. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Biological experiments, observing biological cells
The following steps and precautions were needed to observe biological cells in biological experiments: ** I. Preparing Work ** 1. ** Prepare the specimen ** - For observing plant cells, he could prepare specimens such as the lower surface of broad bean leaves, plant root tips, onion skin, etc. For animal cells, he could prepare specimens such as frogs, mice, and human cells such as oral cells, red blood cells, nerve cells, bone cells, etc. 2. ** Instrument preparation ** - Light microscope (self-prepared) or hand-held microscope. If you want to use a light microscope, you need to place the microscope properly and light it. For some special observations, such as using the Echo Rebel upside-down microscope, there was no need to equip a computer. The iPad Pro was small and light enough to display the image. It could also be placed in the incubator for observation, and it was wireless connected to the iPad for easy operation. ** 2. Observation process ** 1. ** Plant Cell Observation ** - Taking the surface cells of broad bean leaves as an example, one could observe the crescent-shaped guard cells and irregular surface cells. In the middle of the guard cells were stomata, which were the channels through which gas passed when plants carried out photosynthesis and breathing. The root tip cells in the root tip of the plant were relatively regular, like small rectangular grids densely arranged. Plant cells had a cell wall on the outside, a cell membrane on the inside, and a variety of structures such as vesicles, plastids, and nuclei. 2. ** Animal Cell Observation ** - Frog cells had no cell walls, and they absorbed oxygen from the air through their skin cells while keeping their skin moist. The human oral cavity was composed of irregular flat and hexagonal cells. The nerve cells were divided into two parts, the cell body and the process. The cell body was a hexagonal bulge that was intertwined like a tree root. The human bone cells had many types, such as flat oval bone cells with many bulges, contracted bone cells, short cylindrical or cubic bone cells, multi-nuclear bone cells, and so on. ** 3. Cell State Judgment and Analysis ** 1. ** Medium related (for cell culture)** - Pay attention to the color of the culture medium. Most of the culture medium contains an acid and base indicator. If it is slightly acidic, it will appear yellow, and if it is slightly basic, it will appear purple. When the pH-value changes greatly, it is necessary to consider whether the culture medium is contaminated, the cells are growing too densely, the cells are dying too much, or the concentration of CO2 in the incubator is adjusted. If the culture medium becomes turbid, it may be contaminated or the cells are growing too densely. 2. ** Cell shape and growth state ** - The cells in suspension culture were in a clustered state, while the cells in attached culture were in a free state. Before operating the cells in the ultra-clean bench, if the cells were cultured in conical flasks or petri dishes, it was best to observe the cell growth under the 40x objective lens of the inverted microscope. By observing biological cells, one could understand the structure and function of cells, as well as the differences between different biological cells. These observations would help to understand the law of life activities of living things. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The non-biological parts of the biological system are
The non-biological parts of the ecosystem included sunlight, water, temperature, soil, air, mineral salt, humidity, heat energy, etc. These non-biological parts were the foundation of the ecosystem, providing the material and energy basis for the survival of living things. The quality of its conditions directly determined the complexity of the ecosystem and the richness of the biological community. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What is the principle of the biological fermentation bed's mechanized process?
The mechanized principle of the biological fermentation bed mainly involved the working principle of the raking machine or the throwing machine of the fermentation bed. Firstly, the manure from the farm was collected and evenly spread on the bedding in the fermentation tank. Then, the manure and the bedding were fully mixed by the fermentation bed rake or the throwing machine. During this process, the crude protein, crude fat, residual starch, carboric acid, and other organic compounds in the manure were degraded or decomposed by the use of the fermentation of the microorganisms, producing oxygen, carbon dioxide gas, water, decaying substances, and heat. The temperature in the center of the fermentation tank could reach more than 55 degrees Celsius. Through the flipping of the flipping machine, the water in it would evaporate, leaving only a small amount of residue that would eventually become organic fertilizer. This mechanized operation could enable organic waste to quickly achieve biotechnology, dehydration, sterilization, detoxification, and fermentation, achieving the purpose of harmless, resourceful, and reduction treatment. Moreover, it had low energy consumption, stable product quality, and compact structure. It could make full use of some beneficial microorganisms to promote the rapid fermentation of organic waste such as livestock manure. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Does biological science include biological engineering?
Although bioengineering was related to biological science, bioengineering was not included in biological science. In terms of the choice of major for the postgraduate entrance examination, the biological science major could choose the bioengineering direction because many of the knowledge points of the two were similar and inherited. At the same time, the postgraduate entrance examination for biological science majors could also take the examination of biochemistry and molecular biology, botany, subject teaching (biology), cell biology, and other majors. They could also choose to major in biomedicine engineering. The postgraduate entrance examination for bioengineering majors included bioengineering pharmaceutical, biotechnology and food engineering, etc. You could also take the entrance examination for biological science, biotechnology, bioinformation, biostatistics, and other majors. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The difference between biological information and biological materials
Bioinformation was a subject that used the comprehensive use of biological big data, machine learning, and complex networks to reveal the mysteries of biology contained in large amounts of complex biological data. Biomedicals were a type of natural or synthetic special functional materials that could be used to contact and interact with living systems. They could diagnose, treat, replace, repair, or induce regeneration of cells, tissues, and organs. They were also known as biomedicals. There were obvious differences between the two in terms of concept and function application. One focused on the revelation of the mysteries related to biological data, while the other focused on the realization of specific functions in living systems. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Biological Oxidation
Bio-oxidization was a process that occurred in the body of an organism. It involved removing hydrogen and electrons from the metabolism, synthesizing water and releasing energy through a series of biochemical reactions and oxidization. It also covered a series of processes in the body of organisms. The main purpose was to provide usable energy for the body. In biological fermentation, the formation of CO2 was caused by the decylating reaction of organic acid in metabolism. The neutrons and electrons removed during the fermentation process were usually transferred to oxygen by carriers such as NAC to produce water. The P/O ratio referred to the number of moles of phosphorus atoms consumed for every mole of oxygen atoms consumed during the fermentation of the metabolism, which was also the number of moles of synthesized ATP. Cell breathing was also a biological process of oxidization. It was a process in which biological molecules such as glucose, fatty acid, and so on were oxided in the cell to obtain energy and produce CO2. The specific performance was the consumption of oxygen and the production of carbon dioxide, water, and adenine triphonate (ATP1). The main place of biological oxidization was the mitochondria, which was like an energy factory in the cell. For example, glucose was produced into ATPthrough a series of chemical reactions in the mitochondria. This process was known as oxygen metabolism. In addition, under special circumstances (such as when the mitochondria are too busy during strenuous exercise), the body will initiate non-mitochondria fermentation (such as the muscle's Creatoxin Kinase can extract energy from glucose or other substances without the help of mitochondria). The biological fermentation process could be roughly divided into three stages: gly colysis (which takes place in the cell, breaking down the glucose into smaller molecules without the need for oxygen and producing a small amount of energy), the lemon acid cycle (the small molecules enter the mitochondria for further processing and release more energy), and the oxyphosphorification (the small molecules combine with oxygen to release a large amount of energy to generate bound bound "The Island of Life" is also a wonderful novel.

This is a biological comic
I don't quite understand if your statement of " this is a biological manga " is a statement or a question. If you want me to introduce some content related to biological comics, there are many biological comics for reference. For example," Agent X's Human Adventures " was a collection of adventure stories, hilarious comics, and hardcore science. It was a sub-series of the " X Exploration Special Agent Team " that could transform complex biological knowledge into vivid comic stories. For example, the human blood vessels were compared to roads, and the blood plaque was compared to a small person driving a car to explain the working principle of the human blood circulation system. There was also Comic Biology, which introduced all aspects of life from the microscopic to the macro level, such as the nature of life, the units that make up life, the biochemical reactions within and between cells, genes, organs, systems, and the classification and evolution of species in nature. It used comics to outline the whole picture of biology. In addition," My First Interesting Science Comic Book: Interesting Creatures "," Miwu Interesting Encyclopedia: Biology Volume " and other comics could also help readers easily understand biological knowledge.
