In the second volume of biology, nutrient exchange mainly involved the exchange of nutrients between the fetus and the mother, as well as the absorption of nutrients in the human digestive system. The organ that exchanges nutrients between the fetus and the mother is the placenta. The nutrients and oxygen in the mother's blood enter the fetus through the placenta, while the carbon dioxide and waste produced by the fetus enter the mother through the placenta. In the human digestive system, nutrients in food such as starch, fat, protein and other large molecules, organic matter with complex structures are gradually decomposed into simple substances in the digestive system and absorbed. For example, the saliva glands in the oral cavity secrete saliva, which contains saliva starch to digest starch. The gastric glands secrete gastric juice, which contains pepsin to digest protein. The small intestine is the main place for digestion and absorption. Here, nutrients are fully digested and absorbed into the blood circulation, and then transported to cells throughout the body for use. The nutrients that the human body needed were mainly sugar, fat, protein, water, mineral salt, vitamins, etc. Among them, sugar was the most important energy supply material for daily activities of the human body, fat was the backup energy material, protein was the basic material that constituted human cells and participated in the repair and regeneration of damaged cells, water was the main component of cells, mineral salt was an important component of human tissues, and vitamins played a regulating role in human life activities. These nutrients were exchanged from the outside world to the human body through the digestion and absorption process of the digestive system to maintain normal life activities. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

[Green Bean Germination Observation Diary] On the first day, I found some green beans. They were small, green, and hard to the touch. I put the green beans into a small bowl and added an appropriate amount of water to let them soak. The green beans were like small green gems, lying quietly at the bottom of the water. The next day, I found that the green beans had become fatter. Their green clothes seemed to be stretched tightly. Some of the green beans had even begun to peel, revealing their white bellies, like naughty children showing off their bellies. On the third day, the green beans grew small buds. The small buds were white and tender, like small commas. The green beans 'skin had completely fallen off, and they looked even more plump. I changed the water for the green beans, hoping that they would continue to grow healthily. On the fourth day, the green bean sprouts grew longer. They curved like small tails. The bean sprouts were squeezed and some were even entangled with each other, full of vitality. Looking at these green bean sprouts, I felt the magic and vitality of life.

1. ** The definition and composition of organic matter ** - The organic matter contained carbon and could be burned. For example, in cells, sugar, fat, protein, and DNA were all organic substances, and they were also large molecules. 2. ** Knowledge related to organic matter in green plants ** - In the experiment of green plants producing organic matter, starch was the product of photosynthesis. Through dark processing (Put it in the dark for a day and a night to remove the original starch in the leaves and exhaust it), select leaves to shade (To form a control experiment, the variable is light), sunlight exposure, alcohol detoxification (alcohol acts to dissolve the photosynthesis, and heating with water to prevent the alcohol from evaporating and burning, the color of the alcohol changes from colorless to green, and the color of the leaves changes from green to yellow-white), rinsing with clear water, dripping with iodination solution (to verify whether there is starch formation), rinsing with clear water, and so on. The conclusion can be drawn that starch is a product of photosynthesis and plants require light for photosynthesis. - The reaction formula for photosynthesis was carbon dioxide + water, organic matter (which stored energy)+ oxygen. The organic matter here was the product of photosynthesis. The raw materials of photosynthesis were carbon dioxide and water. The condition was light, and the place was the plastids. The essence of photosynthesis was to produce organic matter and store energy. - At the cellular level, organic matter constructs the plant body, such as the fiber in the cell wall, the protein and fat in the cell membrane, and the DNA in the nucleus. 3. ** Knowledge related to organic matter in the ecosystem ** - In an ecosystem, producers (usually green plants) can produce organic matter for themselves and other organisms to use. The organic matter flowed along the food chain and food web. The matter could be recycled, but the energy flowed in one direction and decreased step by step. At the same time, harmful substances gradually accumulate along the food chain. The higher the nutritional level, the more toxic substances (bioconcentration). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following is a thought map about biological fruits (suitable for the third grade knowledge level): ** Central theme: Biological Fruit ** ** 1. Fruit Formation ** 1. Flowers - Flower structure (briefly mention pistil, stamen, and other parts related to fruit formation) - Pollinating (the process of pollen spreading to the pistil) - Fertility (an important step in the formation of fruits) 2. development - Ovary Change (Ovary will develop into a fruit) - Ovule change (Ovule developing into seed) ** 2. Type of Fruit ** 1. By structure - A simple fruit (such as an apple) - Compound Fruit (Can be used as a simple example to describe the situation where many small fruits are combined together) 2. According to the characteristics of the flesh - Fleshy Fruit (Fruits with more flesh like peaches and pears) - Dried fruit (such as nuts) ** 3. Function of the Fruit ** 1. To the plant itself - Protect the Seed (Protect the seed from external harm) - Spreading seeds (for example, after some fruits are eaten by animals, the seeds will be discharged and spread to other places) 2. on human and animal - Food Source (list common edible fruits) - Some fruits can be used for other purposes (such as making crafts and other simple examples) <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following is an analysis of the fourth grade English PEP test questions: ** I. Overall Proposition's Characteristics ** 1. ** Pay attention to basic knowledge ** - For example, the letters (including the stroke order of the letters, the alphabets, the left and right neighbors of the letters, etc.), the word test (three and four words), etc. These were all the basic content for the students 'subsequent English learning. For example, in some test papers, the ability to memorize three words was tested by listening to the recording and choosing pictures, words, or sentences. The ability to use four words was tested by listening to the recording and adding sentences. 2. ** Penetration of Ability Test Requirement ** - In the design of the paper questions, the students 'reading comprehension ability and language ability were tested. For example, there would be questions such as judging whether a sentence was correct or wrong according to a short passage. This not only required the students to know the words, but they also needed to understand the meaning of the sentence and the content of the short passage. They also needed to use the English knowledge they had learned to accurately judge the answer. ** 2. Analysis of each question type ** 1. ** Listening section ** - ** Listen to the recording and choose a picture, word or sentence (Test your ability to remember three words)** - The three words in this part of the exam were the key words that the students were required to master in the textbook. Some of the students lost their marks mainly because they had poor ability to distinguish pictures. For example, some pictures corresponding to words with similar appearances were easy to confuse, such as donkey and ox,tomato and potato. - ** Based on the recording content, determine whether the picture matches the recording content (check the content of Let's do)** - This kind of question was closely related to the students 'usual listening, memorizing, and doing more actions. Most students could do it correctly. - ** Listen to the recording and choose the answer to the question (Listening and Speaking Practice for Daily Sentences)** - This was the difficult part of the listening test, which required the students to use their ears, brain, and eyes. They had to listen to the questions clearly, think of the answers, and choose the correct ones among the similar answers. This required the students to practice a lot of the key sentences in each unit. - ** Listen to the recording and add sentences according to the cloud map (Test the ability to use words)** - It was not difficult for most students who could memorize words, but a small number of students who were new to the cloud map might not be able to find the correct words because they did not understand it. - ** Listen to the recording and choose the corresponding word (Test the pronunciation of the word)** - Since this book focused on the pronunciation of the five syllables, A, E, I, O, and U, as long as the teacher combined the pronunciation rules with the teaching and let the students try the pronunciation of the new words, the students would be able to do this kind of question more easily. 2. ** Written test ** - ** Alphabet part ** - The examination of the stroke order of the letters, the alphabets, and the neighbors of the letters was to consolidate the basic knowledge. However, the problem was that some of the old knowledge that had already been learned, such as handwriting, was the focus of the previous semester. When it was mentioned less this semester, the students 'repetition rate was very low, and it was easy to lose points. - ** Words ** - The test format of reading Chinese and writing English was relatively monotonous and boring. It was not suitable for fourth-grade students who had just learned to write from memory, and it was easy to cause confusion. - ** Voice part ** - The main test was the pronunciation of the syllable letters in the single-syllable and closed-syllable words. This part was an elective content. It was relatively new to the students and had a certain degree of difficulty. However, if the teacher emphasized more, the students would be able to master it better. - ** Sentence Patterns ** - This part required the students to be able to correctly use the sentence patterns they had learned in their daily life to answer questions, such as the ability to understand and convert sentences. - ** Comprehensive application part ** - Students were given a short passage to judge whether the sentences were correct or wrong. This tested the students 'reading comprehension ability and comprehensive application of knowledge. ** 3. Difficulty of the test paper and the situation for students of different levels ** 1. ** Difficulty reflected on students of different levels ** - For the top students, the test paper was more suitable to test their knowledge mastery. However, for middle and lower class students, the difficulty was on the high side. For example, in the entire test paper, the middle and lower ranked students lost more marks in the parts such as alphabets and pronunciation. 2. ** Analysis of the reasons for poor grades ** - The key to the students 'poor English results was that they could not read or remember the words. In addition, the form of the test would also affect the students 'results. For example, the single form of the four-word test and the three-word test would make some students uncomfortable. Moreover, the students 'ability to read and identify was affected by many factors. Other than their own factors, the learning atmosphere was also very important. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
