Changes in the composition of the biological environment
The composition of the internal environment could be divided into three categories, and the changes were as follows: 1. The substances absorbed by the small intestine that needed to be transported in the blood plasma and mucus, such as water, mineral salt, glucose, protein, fatty acid, vitamins, etc., would change with the cell metabolism in the body and the changes in external environmental factors. For example, after eating food, the amount of nutrients such as glucose might increase, and during the process of energy consumption such as exercise, substances such as glucose would be consumed and reduced. 2. The synthesis and secretion of substances such as secreted protein (e.g., antibodies, lysmokines), neurotransmitter, hormones, etc. synthesized by cells are regulated by the physiological state of the body. For example, when the body was attacked by a pathogen, immune cells would increase the synthesis and secretion of the immune system. Under different physiological cycles or stress conditions, the secretion of hormones would change accordingly, which would lead to changes in these components in the internal environment. 3. Metabolite products of cells, such as carbon dioxide, water, and ureas, are continuously produced during cell metabolism and enter the internal environment. Then, they are expelled from the body through the respiratory system and the urine system. When the rate of metabolism changed, the amount of these metabolism products would also change. For example, during exercise, cell metabolism increased, and the production of carbon dioxide and ureans increased. In addition, the substances in the internal environment, such as Na ions, Cl-ions, and hydrogen carbonate-ions, would also change with the changes in external environmental factors and the metabolism of the cells in the body. The size of the plasma osmolarity was related to the content of mineral salt and protein. When the content of these substances changed, it would affect the plasma osmolarity, which would then reflect the changes in the internal environment. Normal human plasma has a pH of 7.35 - 7.45, and the ph of the internal environment may also fluctuate due to the production and discharge of acidic or basic substances. In short, the chemical composition of the internal environment was constantly changing and not fixed. Read more exciting novels for free
The composition of the biological model
Biological models were mainly divided into three types: physical models, concept models, and mathematical models. - Physical models were presented in the form of physical objects or pictures. Their distinctive feature was to simplify the structure or process that was difficult to observe directly, enlarge or shrink it according to a certain proportion, grasp the essential characteristics, and then express these characteristics through physical objects or pictures. For example, the three-dimensional structure model of eukaryonic cells, the model of the changes of the embryos during Meiosis, and the DNA double spiral structure model were all physical models. - The concept model used words, lines, and symbols to connect related terms or processes. There were two main types of flow chart models and concept map models. The flow chart model represented the sequence of biological processes, and the concept map model represented the relationship between concepts. It could build a knowledge network and explain the life phenomena and activity patterns clearly. - Mathematical models used letters, numbers, and symbols to establish equations or discrepancies, as well as mathematical expressions such as images and charts to describe the characteristics and internal relations of things. They could describe life phenomena, study life phenomena, and solve biological problems through logical reasoning, calculation, and solution. For example, the "J" curve and "S" curve of population growth, the relationship diagram of temperature and pH-dependent activity of the protein, and the calculation of population density were all mathematical models. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What are the components of the biological environment?
The living environment consisted of both non-living and living parts. The non-living parts included sunlight, water, air, soil, temperature, and so on. The basic conditions for the survival of living things were nutrients, sunlight, air, and water, as well as a suitable temperature and a certain living space. The biological part included all kinds of creatures. Within a certain space, the unified whole formed by living things and the environment is called an ecosystem. The biological part of its composition includes producers (mainly green plants, which produce organic matter through photosynthesis), consumers (animals), and decomposed (bacteria, fungi, etc., which can decompose organic matter into organic matter). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
A novel composition with environment and characters
The main component of biological composition
Living things were mainly composed of protein, water, and nuclei. Among them, protein was made up of the main components of the body, which were the main carriers of life activities. Nucleic acid was made up of the main components of the body, which were the carriers of genetic information. Water provided a liquid environment for biochemical reactions in the body. Other than viruses, all other organisms were made up of cells. A cell is composed of a cell's plasma, a cell membrane, and a nucleus. There is also a layer of cell wall on the outermost layer of a plant cell. The main components of the cell wall are Celluloses, Hemicelluloses, and Pectins. The cell's plasma is mainly composed of a cell skeleton composed of protein. The cell membrane is composed of Phospholiptides and Glycoprotein. The nucleus is mainly composed of the cell's genetic material, the Nucleic Acid. From the perspective of elemental composition, the common elements of sugar, fat, protein, and nuclear acid were C, H, and O. The protein also contained elements such as N, and the nuclear acid also contained N and P. There were also views that the basic substances of living things were biochemistry, which were mainly composed of carbon dioxide, nitrogen, water (hydrogen and oxygen), and toxic chemicals. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Paintings of the ecological environment and biological richness
In order to raise public awareness of the conservation of biological species, many paintings on the theme of biological species conservation were held. For example, the Zhengzhou City Bureau of Zoology and the Municipal Bureau of Education jointly launched a painting exhibition on the theme of conservation of biological resources. They collected works from the kindergarten and primary school in the city. Finally, more than 100 excellent works were selected from 3169 paintings and displayed in stages on the Weixin Official Accounts of "Green Zhengzhou". There was also the 2024 exhibition of paintings on the theme of the conservation of biological resources in Henan Province, sponsored by the Department of ecological environment of Henan Province and co-sponsored by the Henan Green Development Association and the Henan Science and Technology Museum. Since its opening on May 22, it had attracted many visitors. The works showed the richness and importance of biological resources in various forms. In addition, Xuchang City also had a collection of paintings on the theme of conservation. With the theme of "Colorful Biological World", primary school and kindergarten students in the city were encouraged to observe nature and draw the ideal biological world. However, the specific painting pictures needed to be obtained through the corresponding public account display, exhibition visits, or works collection channels. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Is genetic modification helpful to the biological environment? Why?
Genetic modification was beneficial to the biological environment. In terms of reducing pesticide use, some pest-resistant GM crops could effectively reduce the amount of pesticide that farmers needed to spray. This helps to protect farmland, reduce the impact on the ecosystem, and reduce the harm to non-target organisms, such as indirect toxicity to insects, birds, etc., which is conducive to the protection of species. From the perspective of land resources and carbon footprint, GM crops could increase production and slow down the rate of new land reclamation compared to traditional farming. As of 2016, a total of 183 million hectares of land had been saved, forests had been prevented from being cut down, and the biological variety on 1.5 billion hectares of cultivated land had been protected. In 2016 alone, the use of pesticide and carbon dioxide had been reduced by 8.2% and 27.1 billion kilograms, and the environmental discharge of 671 million kilograms of pesticide active ingredients had been reduced. However, GM crops may also have some potential effects on the biological environment. For example, herbicide-resistant GM crops may increase the resistance of weeds, thus increasing the use of weeding agents. Some GM plants will have certain effects on the growing soil through their root secretions or stubble, such as hindering the growth and development of certain microorganisms in the soil, promoting the survival and reproduction of certain microorganisms in the soil, resulting in changes and transformation of nutrients in the soil. Some of the genetically modified plants achieved the autonomy of pollen. They did not need bees and butterflies to pollinate, thus gradually reducing the number of bees, butterflies and other insects in the area. The genetic composition of the surrounding plants would also be affected by the strong reproductive ability of the genetically modified plants, which would promote the genetic modification of the surrounding plants and affect the ecological system of the growing area. In general, GM crops have a positive impact on the biological environment, but there are also some potential impacts that require further research and monitoring. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

A composition of 600 words describing the characters and environment in the novel
The Corner of the Campus In the southwest corner of the campus, there is a small forgotten garden. It is my favorite place and a corner full of stories. When they walked into the small garden, the first thing they saw were the tall ginkgo trees. They were like loyal guards, guarding this small world. The rough tree trunk recorded the traces of time. The cracks were like the marks left by the carving knife of time. Every autumn, the golden ginkgo leaves fluttered in the air like butterflies, and then gently fell, covering the ground with a layer of golden carpet. When she stepped on it, it made a rustling sound, like the whispers of autumn. In the middle of the garden was a small circular flower bed filled with all kinds of flowers. In spring, the roses were in full bloom. They were as red as fire, as pink as rosy clouds, and as white as snow. The flowers were delicate and beautiful, emitting a faint fragrance. Among the flowers, there were a few unknown grasses. They were tender green and looked even more vibrant against the flowers. Around the flower bed was a circle of low holly trees. They were evergreen all year round, and their oily green leaves always flickered with the luster of life. In the corner of the garden, there was an old bench. The wood of the bench was already a little rotten, and the paint had peeled off a lot, but it carried many memories. There were once classmates memorizing words here, couples whispering here, and lonely people silently daydreaming here. Once, I failed an exam and was in low spirits. I came to this small garden and sat on a bench. The surroundings were extremely quiet. Only the sound of the wind blowing through the leaves could be heard. The leaves of the ginkgo tree swayed in the wind as if to comfort me. I looked at the falling leaves and thought that they could still dance so beautifully at the end of their lives. Why should I be depressed by a failure? The environment here seemed to have a kind of magic that could calm people down and re-examine their hearts. Although this small garden was not big and not that eye-catching, it was the most unique existence on campus. Every blade of grass, every tree, every brick and tile here was inextricably linked to the people on campus. It was a place full of warmth and memories. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
