a. Yeast brewing is the use of yeast anaerobic respiration to produce alcohol, so it cannot be ventilated into the fermenter, A is wrong;
b. Because oxygen can inhibit the anaerobic respiration of tetanus bacilli, when dressing the wound, materials such as breathable and soft "band-aids" can be used, b is correct;
c. The way for root cells to absorb inorganic salts is active transportation, which requires carriers and consumes energy, so cultivating and loosening the soil is conducive to aerobic respiration of the root system of plants, thereby promoting its absorption of inorganic salts in the soil, C is correct;
d. Appropriate humidity can ensure the full storage of fruit moisture, so as to ensure the delicious flesh of the fruit; Low temperature can reduce the activity of enzymes in cells, reduce cell metabolic activities, and reduce the consumption of organic matter; Under hypoxic conditions, aerobic respiration is weak, and anaerobic respiration can be inhibited, cell metabolism is slow, and organic matter consumption is less. Therefore, a certain humidity, low temperature above zero, and low oxygen environment are conducive to the preservation of apples, d is correct
Therefore, a

Answer]: One of the reasons why jogging is advocated is that the body does not produce a large amount of lactic acid due to strenuous exercise to cause damage to cells, a is wrong. For most plants, soil compaction or pin should be carried out in time to loosen the soil and breathe, promote aerobic respiration of the root system, and prevent the production of alcohol by anaerobic respiration of plants.
The growth and reproduction of yeast needs to be done under aerobic conditions, but yeast fermentation must be completed without oxygen, so it is correct to control the aeration and produce various kinds of wine using malt, grapes, grains, yeasts, and fermenters. When dressing the wound, it is necessary to use a soft band-aid, otherwise the tetanus bacilli are easy to infect the deep wound and multiply, d wrong. Therefore, choose a shirt with caution.

Answer]:BA, in the process of germination after soaking early rice in the southern rice area, "about 40 warm water drenching" can provide water and suitable temperature for the respiration of seeds, and "frequent replanting" can provide oxygen for the respiration of seeds, a correct;
b. Seeds will produce alcohol when they are stored in the old Tibetan Mengzhou, so when the crop seeds are stored in the old Tibetan Mengzhou market, they should be stored under the conditions of low oxygen and high temperature above zero, and the storage life will be significantly prolonged, b wrong;
c. Oil crop seeds contain a lot of fat, the content of C and H in fat is high, and the content of O is low, and the respiration of oil crop seeds needs to consume a lot of oxygen during germination, therefore, oil crop seeds should be sown shallowly, C is correct;
d. Citrus is "sealed and preserved" in a plastic bag to reduce water dispersion loss and oxygen concentration, thereby reducing the respiration rate of the branches, low oxygen and certain humidity are suitable conditions for the preservation of fresh fruits, d correct.

Respiration takes place mainly in the mitochondria of the cell.
Overview of respiration:
The life activities of living organisms all need to consume energy, which comes from the oxidative decomposition of organic substances such as sugars, lipids and proteins in living organisms. The total process of organic matter in living organisms undergoes a series of oxidative decomposition in cells to finally produce carbon dioxide, water or other products, and release energy, which is called respiration (also known as biological oxidation).
Respiration is a chemical process in which the cells of an organism oxidize and decompose organic matter to produce energy, also known as cellular respiration. Whether autotrophic or not, the energy required to complete life activities in cells comes from respiration. In eukaryotic cells, mitochondria are the organelles most associated with respiration, where several key steps of respiration are carried out.
Respiration Applications:
Fermentation engineering: Fermentation engineering refers to the use of engineering technology to use certain functions of organisms, mainly microorganisms, to produce useful biological products for human beings, or directly use microorganisms to participate in the control of certain industrial production processes. Examples of this are well-known yeast fermentation for beer, fruit wine, and industrial alcohol, lactic acid bacteria for cheese and kefir milk, and fungi for large-scale production of penicillin.
With the progress of science and technology, fermentation technology has also developed greatly, and has entered the stage of modern fermentation engineering that can artificially control and modify microorganisms to make these microorganisms produce products for human beings. As an important part of modern biotechnology, modern fermentation engineering has broad application prospects. For example, DNA recombinant technology is used to purposefully modify the original strain and increase its yield; Microbial fermentation is used to produce pharmaceuticals such as human insulin, interferon and auxin.

a chloroplast b mitochondria c vacuole d cytoplasm Answer: a. Chloroplasts - the site of photosynthesis, which converts light energy into chemical energy and stores it in organic matter It does not fit the topic
B. Mitochondria-site of respiration, which releases the chemical energy stored in organic matter for cell utilization
c. Vacuole-The cell fluid in the vacuole dissolves a variety of substances that do not conform to the topic D. Cytoplasm-The cytoplasm contains many substances The cytoplasm of living cells is fluid, which is conducive to the exchange of substances between the cell and the external environment It does not meet the topic
Therefore, b

Choosing a to topping cotton is to remove the apical dominance, which is related to auxin.
Lowering the greenhouse temperature at night can reduce the activity of enzymes related to cellular respiration, reduce the intensity of cellular respiration, and reduce the consumption of organic matter.
Sun-dried wheat seeds reduce the water content in the seeds, which can inhibit the progress of cellular respiration, and all chemical reactions in living organisms require the participation of water.
The sealed cellar contains less oxygen and inhibits cellular respiration. Although anaerobic respiration can be performed, it is relatively mainly aerobic respiration that consumes organic matter in vegetables and fruits.
-
AB lowers the temperature to weaken respiration, consumes less organic matter, and increases crop yields.
C wheat is dehydrated and cannot respirate, d is not explained.
-
a.Vacuum packaging can isolate the air and oxygen participate in the reaction is the third stage of aerobic respiration.
b.Rice is the root cell anaerobic Xun pants The product of the first inhalation of the exhaler is alcohol, which is harmful to plant cells.
c The brewing of wine is based on the principle of anaerobic respiration.
d should be the application of photosynthesis.
Therefore, D should be chosen

The answer is: BTopping of tomato plants is performed to increase yields.
In item b, the topping of tomato plants was to remove the inhibitory effect of the apical bud on the side buds of the tomato (remove the apical dominance), grow more side branches, and increase the yield of the long tomato.
-
b Among them, ACD is the use of various galena methods to reduce the effect of low respiration, A is to reduce moisture, C is to reduce temperature, the temperature difference between day and night is large, the accumulation of organic matter is more, D is to increase the concentration of CO2, inhibition of respiratory Huai spine effect. b is related to auxin.
-
b, it is related to hormones, in order to reduce the concentration of auxin in the lateral buds, so that it develops into lateral branches, more fruits.
Reason for choosing D2342: sodium added to saturated magnesium chloride solution will not undergo a displacement reaction, but sodium first reacts violently with water to form sodium hydroxide and hydrogen gas, and sodium hydroxide dissolved in water will form white flocculent magnesium hydroxide with magnesium chloride (this is the same as the sodium tried to react with copper sulfate in class). >>>More

a.A marker gene is a gene with a known function or a known sequence that can play a specific role as a marker. In the sense of genetic engineering, it is an important marker for recombinant DNA vectors, which is usually used to test the success of transformation.
