Which of the seven biology lessons is the most important knowledge point?The second volume of biology in the seventh grade contained many chapters. Different chapters had important knowledge points. It was difficult to absolutely determine which lesson was the most important.
For example, in the "origin of humans" section, the common ancestor of modern apes and humans was the forest ape, the chimpanzee was the closest to humans, and whether or not they could make tools was the fundamental difference between humans and animals.
In the chapter of "Human nutrition", the six types of nutrients needed by the human body (sugar, fat, protein, water, mineral salt, and vitamins), the three major energy-supplying substances in the human body (sugar, fat, and protein), human growth and development, as well as the repair and regeneration of damaged cells, could not be separated from protein. The proportion and role of water in the human body, although the human body's demand for vitamins was small, it was indispensable, and other knowledge points were more critical.
In the "Human Breathing" chapter, the respiratory tract (nasal cavity, throat, throat, trachea, bronchi, and pneuma) was the passage for gas to enter and leave the lungs. It had the function of cleaning, wetting, and warming the inhaled gas. The lungs were the place for gas exchange.
In the content of "Blood transfusion and blood type," blood type was discovered by Austrian scientist Karl Landsteiner and had hereditary characteristics. Safe blood transfusion followed the principle of blood transfusion of the same type, and a small amount of special blood type blood could be slowly transfused in an emergency. The relevant requirements for voluntary blood donation (18 - 55 years old, good health, voluntary principle, blood donation volume requirements, etc.) were also very important.

Does junior high school biology need to make up lessons? Know the answerWhether or not junior high school biology students needed to make up lessons depended on their learning situation and personal learning habits. If a student's foundation was poor or their study habits were not good, making up classes might be an effective way to improve their grades. This was because biology scores would be included in the total score of the middle school entrance examination and affect the final score. One-on-one tutoring classes could help them master the knowledge and adapt to the difficulty of the course in advance. It was especially important for students who had just started to come into contact with biology courses. For students with a certain foundation and good study habits, school studies may be enough to meet the requirements of the examination, and there is no need for additional tuition. In short, parents should decide whether to make up for the missed classes according to the child's actual situation, and respect the child's wishes and learning feelings. If they decide to make up for the missed classes, they should choose appropriate methods and resources to ensure that the learning effect is maximized.

Can general biology and biology be adjusted?If it was a biology major adjustment, in principle, it should be under the same first-level discipline. The first four digits of the professional code of a volunteer application and the application for transfer should be the same, and the subjects of the biology major adjustment should be the same or similar to the subjects of the transfer major. The national unified proposition subject of the preliminary examination should be the same as the national unified proposition subject of the transfer major. Whether general biology and comprehensive biology could be adjusted depended on the specific school policy requirements, because different schools might have different regulations on the preliminary examination subjects. Some schools might require the same or similar subjects as the school's preliminary examination subjects. For example, they might require the professional courses (such as general biology, comprehensive biology, etc.) to be the same or similar to the school's settings. At the same time, there might be other requirements such as undergraduate major, total score, single subject score, etc. Therefore, based on the two subjects of general biology and comprehensive biology alone, it was impossible to determine whether they could be adjusted. It needed to be analyzed in conjunction with the specific school's adjustment policy.

A masterpiece of biologyThere are many masterpieces about biology. The following are some of the famous masterpieces:
Cell Biology:A Clinic Introduction to the Study of Living Systems by Richard B Ansell.
Biochemistry:The Biochemistry of Life by D. W. Anslinger.
The Evolution of Life by E O Wilson.
4. The Study of Living Things by David R Fisher.
5. The animal behavior of Humans and other animals by Richard A. Ishii Yoko.
6. The botany of plants by John R. O.
These masterpieces covered many aspects of biology, from the cellular and molecular level to the macro ecology. They all made important contributions to the development and research of biological science.
Books on BiologyBiology books referred to books on biology, which usually covered everything from basic biological knowledge to advanced biological research. Biology was the study of life phenomena and organisms, including cell biology, molecular biology, genetics, ecology, biology, biochemistry, and many other branches.
There were many types of biology books that could be divided into classic biology textbooks, biology popular science books, biology research papers, and so on. Classic biology textbooks usually included knowledge of molecular biology, genetics, cell biology, ecology, etc., which were important foundations for biological research. Biology popular science books usually introduced various biological phenomena and the characteristics of biological families to help people better understand biological knowledge.
In addition to books, research papers in biology books were also an important source of knowledge. These papers usually covered a variety of biological research results, from basic experiments to advanced analysis.

Biology and ChemistryBiotechnology is a technology that applies the basic principles of biology, chemistry, and engineering to produce useful substances or provide certain services to humans by using organisms (including microorganisms, animal cells, and plant cells) or their components (organelle and zymes). It includes traditional biotechnology and modern biotechnology. The achievements of genetic engineering and cell engineering in modern biotechnology have attracted more and more attention in solving energy crises and environmental pollution.
Chemistry was a science major. The duration of study was four years, and he was awarded a bachelor's degree in science. This major mainly involved the basic theoretical knowledge of chemistry and basic experimental skills. It studied the chemical reactions and changes within a single substance and between multiple substances to understand their mechanisms and processes. Chemistry students needed to master basic theories, experimental skills, understanding of development history and cutting-edge trends, and other aspects of knowledge. They also needed to have methods and means in chemical research or chemical production, basic problem solving skills, safety awareness, environmental awareness, and other abilities.
Both were professional fields related to natural sciences. Biotechnology would apply chemical principles. The knowledge of chemistry could provide theoretical support for biotransformation and production of biological products in biotechnology. For example, in chemical biology, chemical techniques, tools, and theories were used to study the structure, function, and biological process intervention of biological molecules. This reflected the cross-integration of chemistry and biotechnology related research.

Biology AwarenessThe biological literacy goals mainly included the following four aspects:
1. [Concept of life: This is an abstract result of explaining observed life phenomena and their relationships or characteristics. It is an idea or viewpoint that has been verified.] It was based on a good understanding of biological concepts, forming concepts such as structure and function, evolution and adaptation, steady-state and balance, matter and energy, and so on. They could use these concepts to understand the diverse, unified, unique, and complex life phenomena of living things, and construct a scientific view of nature and the world to guide the exploration of the laws of life activities and solve practical problems.
2. " Rationally thinking: Requires respect for facts and evidence. Adheres to a rigorous and pragmatic attitude of seeking knowledge. Use scientific thinking methods such as induction and summary, deduction and reasoning, model and modeling, critical thinking, and creative thinking to understand things, solve practical problems, and gradually develop corresponding thinking habits and abilities.
3. [Scientific inquiry: Able to discover biological problems in the real world. Able to observe, ask questions, design experiments, implement plans, and communicate and discuss results based on specific biological phenomena.]
4. " Social responsibility: Based on the understanding of biology, participate in discussions about personal and social affairs, make rational explanations and judgments, try to solve biological problems in production and life, and show due responsibility and ability.

Alien BiologyExtraterrestrial biology (astrobiology) used a combination of principles from biology, chemistry, physics, geography, and astronomy. Since there was no conclusive evidence of the existence of extraterrestrial life, most of the research was guided by the information of life on Earth to explore life outside of Earth. Their research covered many aspects, such as the search for signs of extraterrestrial life. Since the mid-20th century, humans have used methods such as detecting radio waves outside the Earth and observing potentially habitable planets with astronomical telescopes to carry out related explorations. Although no extraterrestrial life had been discovered yet, some people thought that the probability of discovering aliens was small, while others thought that extraterrestrial life was almost certain to exist. Moreover, there were at least 100 million planets in the Milky Way that had the conditions to nurture life, such as the existence of suitable temperatures and chemical conditions. At the same time, there were also a lot of imaginations and descriptions of extraterrestrial life in science fiction, which also reflected people's curiosity and exploration of extraterrestrial life to a certain extent.
