What does the biological and non-biological cycle include?
The material cycle occurred between the biological community and the non-biological environment. In a natural state, the material cycle between the biological and non-biological parts of the ecosystem must rely on producers and decomposing. The producer could synthesize the organic matter in the environment to store energy, and the decompose could decompose the organic matter in the remains of animals and plants into the organic matter, so that the materials of the ecosystem could be recycled. For example, in an ecosystem, green plants (producers) let carbon dioxide enter the biological community, and the decompose would decompose the biological remains into minerals and return to the non-biological environment. The basic elements that make up living things can circulate between the living and non-living worlds. Elements such as carbon and nitrogen can circulate between the living and non-living worlds. After a creature dies, it goes through a series of decomposition processes, and its remains are finally transformed into organic matter. This cycle of material and energy is also a manifestation of the cycle of living and non-living things. For example, flowers wither and fall into the ground, and the decomposed land absorbs nutrients to support the growth of plants. After the whale dies, its corpse will become food for marine creatures, providing nutrients for their reproduction. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The basis for all living things to maintain their biological activities is
The basis for all living things to maintain their life activities was metabolism. Metabolism included obtaining nutrients from the outside world and expelling the waste products from the body. On this basis, living things had life characteristics such as growth, reproduction, and stress. <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>

Biological factors affecting plant diseases
The biological factors that affect plant diseases are mainly biological pathogenic bacteria. The following are some common types: 1. Parasitic Seed Plants: For example, dodder, which is a completely parasitic herbaceous plant. It has the ability to climb, has no roots, and its leaves degenerate into scales. It has strong reproductive ability and can reproduce through seeds or stems. It grows with the help of climbing objects and cannot carry out photosynthesis. 2. Nematode: A small, low-level animal. Some live in the soil, and some live on the roots or leaves of plants. They are very harmful to flowers and often cause diseases, such as chrysanthemum leaf wilt. 3. ** Phytoplasma **: Pathological symptoms include yellowing, bushy branches, dwarfing, flower leaves, etc., such as bubble-hole witches 'broom disease, chrysanthemum yellowing disease, etc. Bacteroids were between bacteria and microorganisms. They were larger than viruses and smaller than bacteria. They were low-grade cellular organisms and mainly relied on plant transplantation and leafhoppers as a medium for transmission. 4. ** Virus **: An extremely tiny particle composed of two main components, namely a protein and a protein. It is smaller than bacteria and can pass through ordinary filter paper. It can only be seen with a microscope. After the vegetation was infected, the leaves or flowers would show abnormal growth, clumps, dwarfism, shortened internodes, wrinkles, partial necroses, yellowing, mottled, yellow-green leaves and other traits. It could be transmitted through various breeding methods of insects and plants, such as chrysanthemum virus disease and string of red virus disease. 5. [Bacterias: A single-celled organism, also a low-level plant. They reproduce through division.] The bacteria that harmed garden plants could cause soft rot, root cancer, and leaf spot disease. 6. Fungus: A low-level plant, visible under a microscope. It is multicellularized and cannot produce nutrients by itself. However, it has vegetative and reproductive organs. Its reproductive method is similar to that of higher plants. When the conditions are suitable, spores produced can be transmitted by wind, rain, insects, etc., causing epidemic diseases. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What are the biological functions of growth factors?
It has many biological functions under the mediation of growth factors, including the following aspects: 1. Cell regulation: - By binding to cell membrane or specific receptor in the cell, signals were transmitted into the cell, activating the gene expression related to cell growth and differentiation, thus regulating cell function. - Different growth factors could induce the function of specific cells. For example, nerve growth factor could promote the growth, development, differentiation, and maturity of the central nervous system and peripheral neurons, and maintain the normal function of the nervous system. 2. " Adjusts the body's various systems: skeletal system, hormonal system, blood system, respiratory system, digestive system, reproductive system, immune system, nervous system. 3. Effect in the physiological process of the body: - It played a key role in the body's immune response, inflammation, hemopoesis, and even embryonic development. - It was of great significance in wound repair. For example, it could be used to repair scalds, burns, and ulcers in clinical practice. - It was used in the medical field to treat diseases such as tumors and cardiovascular diseases. 4. It could promote the synthesis of the components of the outer cell matrix. It also had many characteristics such as multifunctionality, high activity, cell growth promotion activity, and orientation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What are the characteristics of rickets biological factors?
The biological factors of rickets mainly involved the following characteristics: ** 1. Regarding the lack of vitamins ** 1. ** Source and Generation Characteristics ** - However, many factors can affect its production. If affected by factors such as season, region, latitude, altitude, etc., the chances of receiving ultraviolet radiation varied greatly. Race and population differences, skin coloring, the intensity of sunlight during the day, and the color and thickness of glass all affected the synthesis of D in the skin. When air pollution is severe, the sunlight is short in winter, or there is insufficient time for outdoor activities, the production of intrinsic D will be insufficient. - From the perspective of diet intake, natural foods that contain vitamins D are rare in nature. Meat, fish, milk, and fish contain very little vitamins D. Human milk and cow's milk also contain very little vitamins D. If the baby is exclusively breastfed and does not add foods rich in vitamins D such as egg yolk and liver paste in time, or children who are vegetarian, they are prone to a lack of vitamins D. - However, if the mother did not take enough of the hormone during pregnancy, the baby would easily suffer from a deficiency of the hormone after birth. 2. ** Effects on the metabolism of calcium and phosphorus ** - When there was a deficiency of vitamins D, it would cause a disorder in the metabolism of calcium and phosphorus, because it played a key role in the regulation of calcium and phosphorus metabolism. The deficiency of vitamins D would affect the absorption of calcium and phosphorus by the intestine, reduce the reabsorption of calcium and phosphorus by the kidney tubulae, and then affect the normal bone mineral process, resulting in rickets, which was characteristic of bone diseases. 3. ** Internal Storage Specialties ** - However, if there was insufficient storage in the body, for example, the mother's lack of storage of vitamins would affect the fetus, or if the baby's own storage was insufficient and could not be supplemented during growth and development, rickets could easily occur. ** 2. Genetic factors (for hypophosphorous rickets)** 1. ** Inheritance Method ** - Low-phosphorous rickets is mainly inherited by autosomal-dominant genetics. This means that if there is a patient in the family, the offspring will have a higher risk of the disease. 2. ** Genetic Effects ** - In addition to genetic factors, there may also be cases of genetic mutations leading to illness. Even if there are no patients with hypophosphorous rickets in the family, the next generation may suffer from this disease due to genetic mutations. This situation is unpredictable and may be combined with some complications, such as hypercalcinuria and X-linked hypophosphorous rickets. ** 3. Trace element imbalance ** - Studies have shown that the serum ALP activity of children with zinc-and iron-deficiency is significantly increased, which affects the metabolism of calcium and phosphorus, and thus affects the growth and development of children. This imbalance of trace elements interfered with the normal physiological metabolism process from a biological point of view and was one of the biological factors of rickets. At the same time, in patients with rickets (such as hypophosphorous rickets), there may be abnormal characteristics of blood biochemical indicators such as low blood phosphorus, normal or low blood calcium and calcium levels, and elevated blood Alkaline Phosphatase during activity, reflecting the disorder of biochemical metabolism in the body. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The Evolution of Living Things
The following are some of the main points of the lesson plan on the process of biological evolution: * * 1. Teaching philosophy and student's main body status ** 1. * * The importance of being student-centered ** - In the teaching of the process of biological evolution, if the traditional teaching method was only one-sided knowledge instilled by the teacher, such as simply explaining the various stages of biological evolution and the evolutionary relationship of different organisms, it would make the students passively accept the knowledge. For example, if the teacher used the "container filling" method in the review class, the students 'participation would be low, and their learning enthusiasm and efficiency would be greatly limited. - The main role of the students should be emphasized. For example, in the revision introduction section, students could be allowed to give pre-class speeches to explain and retell the basic knowledge points, while other students could supplement and question them. This would allow students to discover the gaps in their knowledge and form a systematic knowledge network. At the same time, it would enhance the lively atmosphere in the classroom. 2. * * Change in Teaching Concepts ** - Teachers had to change from imparting knowledge to guiding. In terms of teaching design, one could not just explain and connect knowledge points from the teacher's point of view. One had to take into account the students 'actual cognitive level and learning needs. For example, when explaining concepts related to the process of biological evolution, they had to think about how to guide students to discover the connections between concepts instead of simply telling them. * * 2. Teaching methods ** 1. * * The Use of Comparisons ** - In the teaching of the process of biological evolution, the comparison method has many functions. - In terms of knowledge expansion, students can understand unknown concepts on the basis of known concepts, such as deducing the evolutionary relationship between different organisms by comparing their organ structures. For example, comparing the upper limbs of humans with similar organs of other creatures, although the appearance and function were different, the anatomical structure was similar. This reflected the certain kinship between the creatures. They might have evolved from a common primitive ancestor. This method allowed students to expand their knowledge and deepen their understanding of knowledge. - In terms of knowledge systemization, it could organize fragmented knowledge. For example, when learning the various stages of biological evolution and the characteristics of different biological groups, by comparing the similarities and differences between them, a systematic knowledge system of biological evolution could be constructed. - In terms of concept understanding, it would help students to accurately grasp the meaning and extension of the concept. For example, to accurately understand the concept of the same organ, that is, organs that have the same origin but may have different appearances and functions. 2. * * Problem-solving teaching mode ** - Questions are the starting point of thinking. In teaching, teachers should raise questions according to the teaching outline and students 'cognitive level, and create situations. For example, when reviewing the "Auxin discovery", he could ask a series of interconnected and challenging questions such as "Why do plants that have been placed on the windowsill for a long time grow slanted to the window?" - The students were organized into small group discussions to solve problems. This could promote the exchange of information and the collision of ideas between students. - On the basis of the students 'discussion, the teacher should enlighten and summarize the questions, supplement and correct the inadequacies or mistakes of the students' answers, and guide the students to complete the teaching focus and break through the teaching difficulties. * * 3. Teaching effectiveness and shortcomings ** 1. * * Evaluation of teaching effectiveness ** - By observing the students 'performance in class, such as their enthusiasm in participating in the discussion and their answers to the questions, one could determine the degree of their mastery of the biological evolution process. For example, if the students could actively participate in the discussion of the evidence of biological evolution (such as the same organs, fossils, etc.) and could accurately answer the relevant questions, it meant that the teaching had achieved its goal to a certain extent. - Students could be further evaluated through homework and tests, such as whether they could accurately describe the main process of biological evolution and the relationship between different biological groups on the evolutionary tree. 2. * * Awareness of the inadequacies ** - There might be some shortcomings in the teaching process. For example, the teaching design might not completely take into account the individual differences of the students, which made it difficult for some students to understand some complex concepts in the process of biological evolution (such as the application of molecular biology in the study of biological evolution, such as determining the relationship between biological relatives by determining the structure of protein and nucleus). - The application of teaching methods may not be flexible enough. For example, in the problem solving teaching model, the questions raised may be too difficult or too low for some students, affecting the teaching effect. Teachers should constantly reflect on their teaching ideas and methods, evaluate their teaching effects, and recognize their shortcomings in order to improve the quality of teaching and help students better grasp the relevant knowledge of the process of biological evolution. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
