High School Biology Required Two Concepts Chart1. Chapter 1: The discovery of genetic factors
- Mendel's Pea Crossing Experiment (1): The core concepts include the law of gene separation, orthodoxy, reverse crossing, crossing, self-crossing, F1, F2, test crossing, relative traits, trait separation, genetic factors, etc. There are also dominant traits, hidden traits, dominant genetic factors, hidden genetic factors, heterotymph, homozymph, genotype-type, manifestation, hypothesis-deduction method, etc.
- Mendel's Pea Crossbreeding Experiment (2): The core concepts include the law of free combination of genes.
2. Chapter 2: The Relationship Between Genes and Genes
- ** Section 1 Meiosis and Fertility **: Important concepts include Meiosis, Fertility, sperm, ovum, Meiosis I, Meiosis II, Allele, Non-Allele, Homological Chromatic, Non-Homological Chromatic. Secondary concepts include testes, ovaries, sperm cells, oogonia, primary sperm cells, primary ovaries, secondary sperm cells, secondary ovaries, polar bodies, symphysis, and quadrants.
- ** Section 2: Genes on the Chromosome **: No more details needed to be added.
- ** Section 3: Sex-linked Inheritance **: No detailed section to supplement the content of the concept map.
3. The Nature of Genes
- Chapter 1: DNA is an important genetic material. This includes important concepts such as the transformation experiment of pneumococci and the experiment of bacteria infection by a pathogen. There are also secondary concepts such as bases, adenine, thymine, uracil, and cystine. Isotopic tracing techniques and density gravity centrifugal methods.
- The important concept is the double spiral structure of DNA molecules.
- "DNA Duplication": There are important concepts such as DNA semi-preservation replication, genes, genetic information, and genetic effects, as well as secondary concepts such as uncoiling, the variety of DNA molecules, and the uniqueness of DNA molecules.
- ** Section 4: Genes are DNA fragments with hereditary effects **: The important concept is that genes are DNA fragments with hereditary effects.
4. The Manifestation of Genes
- The important concepts include the embodiment of genes, replication, translation, genetic code, central dogma, etc. The messenger R A (mR A), transfer R A (tR A), Ribosome R A (rR A), codons, and anticodons are secondary concepts.
- [2. Gene Control over Traits]
- ** Section 3: Deciphering the Genetic Code (Selections)
5. Gene Mutation and Other Mutations
- The important concepts are biological variation, non-hereditary variation, inheritable variation, genetic mutation, and genetic reorganization. The secondary concepts include repetition, loss, reversal, and translocations.
- ** Section 2, Chromatic Mutation **: The important concept is Chromatic Mutation. There is no detailed section to supplement the content of the concept map.
- "Section 3 Human Genetic Disease": The important concept is human genetic disease, and the secondary concepts include diploids, polyploids, genomes, haploids, monogeneic genetic diseases, polygenetic genetic diseases, abnormal genetic diseases, and human genetic planning.
6. From Crossbreeding to Genetic Engineering
- ** Section 1: Cross Breeding and Mutation Breeding **: Important concepts include selection breeding, cross breeding, and mutation breeding. There is no detailed section to supplement the content of the concept map.
- "Genetic engineering and its application": The main concept is genetic engineering, and the secondary concepts are target genes, gene carriers, restriction endozymes, DNA ligases, and receptor cells.
7. Modern Biological Evolution Theory
- [1. The origin of modern biological evolution theory: The important concept is the theory of natural selection. There is no detailed description of the concept map.]
- The important concepts are biological evolution, species, biological variation, population, gene frequency, isolation, and co-evolution. The secondary concepts are useful advancement and retreat, acquired inheritance, gene pool, over-reproduction, survival struggle, genetic variation, and survival of the fittest.

Sore throat, stuffy nose, repeated fever, what medicine is effective?If there are symptoms of sore throat, stuffy nose, and repeated fever, it may be an upper respiratory tract infection. It can be treated with Bufferin (This condition is mostly caused by a viral infection and catching a cold, accompanied by symptoms such as sore throat, stuffy nose, fever, etc. If the fever is above 38.5 degrees Celsius, you should choose antipyretic. If it is below 38.5 degrees Celsius, you can relieve it by physical cooling). You can also take Vita-C Yinqiao Tablets and Azithromycins. At the same time, drink more water, rest on time, and avoid staying up late and fatigue.
For nasal obstruction symptoms, you can use anesthetic nasal drops or oxometazolin spray, spray twice a day into each nostrils; For sore throat, you can use lozenges or mouthwash. If the symptoms are serious, you can add Chinese patent medicine for sore throat. If the symptoms are obvious and accompanied by general symptoms such as fever, general discomfort, etc., you may need to use antibiotics, such as cephem or Azithromycins, for comprehensive treatment.
If the cold does not get better after taking medicine for a long time, or fever, sore throat and ineffective drug treatment appear again soon after the treatment is improved, it is necessary to check the thyreoid function as soon as possible. If it is diagnosed as subacute thyroiditis, the fever should be treated with antipyretic treatment. If the pain is obvious, painkillers can be used. If necessary, levothyroxine should be added as replacement treatment.
It should be noted that the specific medication should be reasonably selected according to the individual's situation. If the symptoms are serious or continue to be unrelieved, you should seek medical advice promptly.
