Junior high school biology paper typical problem analysis questions and answers
The following are some typical questions and answers for junior high school biology papers: * * 1. Single choice question ** 1. * * The meaning of the body of the hydra being symmetrical ** - Answer: D (both). - [Analysis: Hydra's symmetrical body shape allows it to sense stimulation from all directions, capture prey from all directions, and defend against enemies from all directions.] This symmetrical way was compatible with its aquatic, fixed, or floating lifestyle. 2. * * Judgment on the difference between high and low animal groups ** - [Question: There are many animal groups, and there are high and low grades. The following statements are incorrect ()] - Answer: B. - [Analysis: Although the body of a thread-shaped animal is cylindrical, it cannot be determined that it is higher than a flat-shaped animal.] The bilateriality of flat-shaped animals was higher than that of coelenterate because the bilateriality made the body of animals have the division of front, back, left, right, back and abdomen, which was conducive to directional movement. Reptiles could fully adapt to land life, which was higher than amphibians. Mammals were better than birds in reproductive development because they were born and suckled. 3. * * The similarities between roundworms and pork taenias in adapting to parasitic life ** - Answer: B. - Analysis: Ascaris lumbricus and pork taeniasis are parasites. The similarity between them and parasitic life is that they have developed reproductive organs, which is conducive to their reproduction in the host's body. They did not need developed digestive organs because they could obtain nutrients from their hosts. The roundworm had a stratum corneum on its body surface, but the pork taeniasis did not. Symmetries on both sides of the body were not unique to their parasitic life. 4. * * The relationship between the cell structure of roundworms and their living environment ** - Question: The roundworm lives in the human digestive tract and does not get oxygen for a long time, so which structure in its cells may disappear () - Answer: C. - "Analysis: The mitochondria is the main place for oxygen breathing. The roundworm lives in an anoxia-deficient environment and carries out anoxia-free breathing, so the mitochondria may degenerate and disappear. The cell membrane was the boundary structure of the cell, the nucleus was the control center of the cell, and the plasma was the main place for the cell to carry out metabolism. They would not disappear due to lack of oxygen. 5. * * Muscle movement when the locust jumps ** - [Question: When the locust jumps, its hind feet change from bending to stretching. The following related statements are wrong ()] - Answer: B. - [Analysis: When the locust jumps, muscle A relaxes and muscle B contracts, causing the hind feet to turn from a bent state to an extended state.] The inner muscles of the hind feet were attached to the inner side of the exoskeleton. The locust's chest had three pairs of feet, and the body and feet were divided into sections. The muscles provided power for the locust's jumping. 6. * * Common characteristics of mussels, snails and cuttlefish ** - Answer: C. - [Analysis: Mussels, snails, and cuttlefish all have a common feature: they all have a mantle.] Mussels had shells, snails had shells, and cuttlefish's shells had degenerated. Snails moved with their stomachs, mussels moved with their axes, cuttlefish moved with their wrists and used them to hunt for food, and mussels breathed with their gills and relied on water pipes and water pipes to obtain food. 7. * * The relationship between animal groups and their characteristics and the map (The map is not shown, so the specific options cannot be analyzed in detail, but the idea is as follows)** - Answer: It depends on the specific choice. - "Analysis: Based on the characteristics of various animals, such as the characteristics of coelenterate, flat-shaped animals, and thread-shaped animals, the animal groups described in the options and their characteristics should be compared to the actual situation, including the characteristics of body structure, lifestyle, physiological functions, and so on. 8. * * Description and judgment of animal structure and function ** - Question: The structure of an animal is always compatible with its function. - Answer: B. - [Analysis: The lizard's body is covered with horny scales, which can prevent the water in its body from evaporating. Lizards use their lungs to breathe. Their skin is dry and does not assist in breathing.] The roundworm's body surface was wrapped in a cuticle for protection; the locust's body surface had a tough exoskeleton that could prevent the water in the body from evaporating; the fish's body surface was covered with scales, and the surface of the scales had slippery mucus to protect the body. 9. * * Escape (Chameleon)'s characteristic description and judgment ** - [Question: Which of the following descriptions about avoiding servitude is correct?] - Answer: B. - Analysis: The body color of the evildoer can change with the environment, which is a protective color; the evildoer has developed lungs and strong gas exchange ability, which is conducive to its breathing in land life; the reproductive development of the evildoer completely gets rid of the dependence on the water environment; the fertilized egg of the evildoer does not need to absorb water and oxygen from the outside world when hatching. 10. * * Description and judgment of animal structure and living environment ** - Question: The following statements about animals adapting to their living environment are incorrect () - Answer: B. - "Analysis: Male frogs have a vocal sac. The vocal sac is the vocal organ of male frogs. It has nothing to do with adapting to life in water or on land. It mainly attracts female frogs during the breeding season. Fish used gills to breathe to adapt to life in the water, pigeons 'forelimbs turned into wings to adapt to flying life, and lizards had horny scales to adapt to life on land. 11. * * The corresponding judgment of animals and their gas exchange sites ** - Answer: C. - Analysis: Paramecium carries out gas exchange through the membrane; earthworms carry out gas exchange through the body wall; snails carry out gas exchange through the mantle; river mussels carry out gas exchange through gills; locusts carry out gas exchange through the trachea, not the lungs; seahorses carry out gas exchange through gills; frogs carry out gas exchange through the lungs and skin; pigeons carry out gas exchange through the lungs, and the air sacs assist in breathing but do not carry out gas exchange. 12. * * Judgment of the relationship between the characteristics of different creatures (The specific circle map of the creatures represented by P, Q, E, and F is not given. It is impossible to analyze the specific choices in detail, but the idea is as follows)** - Answer: It depends on the specific choice. - "Analysis: Based on the characteristics of the organisms involved, such as the way of reproduction of mammoths, the way of reproduction of many animals, the way of obtaining nutrition by heterotrophy, and the characteristics of land animals that can prevent water loss and adapt to land life, the accuracy of the contents of P, Q, E, and F in each option should be judged. 13. * * Gas exchange of birds in flight ** - Question: The following descriptions of birds and mammals are wrong: - Answer: A. - [Analysis: When birds fly, only the lungs can exchange gases. The air sacs play a role in assisting breathing and cannot exchange gases.] Birds 'bones were light, thin, and strong, and their chest muscles were well-developed. * * 2. Non-multiple choice questions (Since the specific content of the questions is not given, the following is an analysis of common test points)** 1. * * Cell structure is related to function ** - For example, if one were to examine the structure of a cell, one might ask about the functions of the cell's structure, such as the plasma, nucleus, and cell membrane. - Answer: The cell membrane has the function of controlling the entry and exit of substances into the cell; the nucleus is the control center of the cell and contains genetic material; the plasma is the main place for the cell to carry out metabolism, and the organelle, such as the mitochondria, is the main place for oxygen breathing (the plastids in plant cells are the places for photosynthesis, etc.). 2. * * The classification basis and characteristics of animals and plants ** - For example, comparing the difference between a vertebra and an insect. - Answer: Vertebrate animals have a spine made of vertebrae, but there is no spine in the body of an animal with no backbone. Vertebrate animals included fish, amphibians, reptiles, birds, and mammals, each of which had different characteristics, such as fish breathing with gills and swimming with fins; young amphibians breathing with gills, adults breathing with lungs and skin, etc.; Invertebrae included coelenterate, platyphores, threadworms, annelids, mollusks, arthropods, etc. The body of coelenterate was symmetrical, with a mouth but no anus; the body of platyphores was symmetrical on both sides, with a mouth but no anus, etc. 3. * * The relationship between living things and the environment ** - For example, how the structure of an animal adapted to its living environment. - Answer: For example, animals in the desert, camels have humps to store fat, wide soles to prevent sinking, long eyelashes to prevent sand and wind, etc. Fish that live in the water have streamlined bodies to reduce resistance, and they use gills to breathe to obtain oxygen in the water. 4. * * Biological reproduction and development ** - For example, comparing the reproductive and development characteristics of insects, amphibians, birds, and mammals. - Answer: Insects are egg-laying and have metamorphosis (complete metamorphosis is like butterflies going through four stages of egg, larva, pupa and adult, and incomplete metamorphosis is like locusts going through three stages of egg, larva and adult); frogs are egg-laying, in addition to external fertilisation and metamorphosis; birds are egg-laying, internal fertilisation, hatching and brooding; mammals are live-laying, breast-feeding, and internal fertilisation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
