The experimental study compared the effect f playing Mine-craft, with or without instruction, to watching a TV show or playing a race video game. Those ____21____ (give) the freedom to play Mine-craft without instruction were most creative.“It’s not just that Mine-craft can help induce creativity. There seems to be something about choosing to do it that also matters,” said Douglas Gentile, a professor of psychology.____22____ you are not familiar with the game, Gentile says Mine-craft is like a virtual Lego world. The game, which has sold more than 100 million copies, allows players to explore unique worlds and create anything they can imagine. Study participants randomly assigned to play Mine-craft were split into two groups. The one receiving instruction was told to play as creatively as possible.After 40 minutes of play or watching TV, the 352 participants completed several creativity tasks. ____23____ (measure) creative production, they were asked to draw a creature from a world much different than Earth. More human like creature scored low for creativity and those less human-like scored high. Surprisingly, those instructed to be creative while playing Mine-craft were the ____24____ (creative).Gentile says there’s no clear explanation for this finding. In the paper published by Creativity Research Journal, he, Jorge Blanco-Herrera, lead author and former master’s student in psychology: and Jeffrey Rokkum,former Ph. D. student in psychology, outlined possible reasons why the instructed Mine-craft group scored lower. Blanco-Herrera says the instructions may have changed subjects’ motivation for play.“____25____ (tell) to be creative may have actually limited their options while playing, resulting in a less creative experience,” Blanco-Herrera said. “It’s also possible they used all their ‘creative juices’ while playing and had ____26____ left when it came time to complete the test.”Video games can have both harmful and beneficial effects. Gentile’s previous research has shown the amount, content and context and video games ____27____(influence) what players learn through repeated experiences. ____28____ much of Gentile’s research has focused on aggression or pro-social behavior, he says the same appears to be true for creativity.Most video games encourage players to practice some level of creativity. For example, players may create a character and story for role-playing games or be rewarded for creative strategies in competitive games. The researchers say even first-person shooter games ____29____ potentially inspire creativity as players think about strategy and look for advantages in combat.“The research is starting to tell a more interesting, nuanced picture. Our results are similar to other gaming research ____30____ ________ you get better at what you practice, but how you practice might matter just as much, ” Gentile said.Section BDirections: Fill in each blank with a proper word chosen from the box. Each word can be used only once. Note that there is one word more than youneed.Major companies are already in pursuit of commercial applications of the new biology. They dream of placing enzymes(酶)in the automobile to monitor ____31____ and send data on pollution to a microprocessor that will then adjust the engine. They speak of what The New York Times calls “Metal-hungry microbes(微生物)that might be used to ____32____ valuable trace metals from ocean water.” They have already demanded and won the right to patent new life forms.Nervous ____33____, including many scientists, worry that there is corporate, national, international, and inter-scientific competition in the entire biotechnological field. They create images not of oil spills, but of “microbe spills” that could spread disease and destroy entire populations. The creation and ____34____ release of extremely poisonous microbes, however, is only one cause for alarm. Completely rational and ____35____scientists are talking about possibilities that stagger(动摇)the imagination.Should we breed people with cow-like stomachs so they can digest grass and hay, thereby ____36____ the food problem by modifying us to eat lower down on the food chain? Should we biologically alter workers to fit the job requirement, for example, creating pilots with faster reaction time or assembly-line workers ____37____ to do our monotonous work for us? Should we use genetic forecasting to pre-eliminate “unfit” babies? Should we grow reserve organs for ourselves, each of us having, as it were, a “savings bank” full of ____38____ kidneys, livers or hands?Wild as these notions may sound, everyone has its ____39____ (and opposers) in the scientific community as well as its striking commercial application. As two critics of genetic engineering, Jeremy Rifkin and Ted Howard, state in their book Who Should Play God? “Broad scale genetic engineering will probably be introduced to America much the same way as assembly lines, automobiles, vaccines, computers and all the other technologies. As each new genetic advance becomes ____40____ practical, a new consumer need will be exploited and a market for the new technology will be created.”III.Reading Comprehension (41 – 55题,每题1分;56 – 70题,每题2分;共45分)SectionADirections: For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits thecontext.Deliberation is not always the best optionHumans have developed over millions of years of evolution to respond to certain situations without thinking too hard. If your ancestors ___41___ movement in the undergrowth, they would run first and ask questions later. At the same time, the ___42___ to analyse and to plan is part of what distinguishes people from other animals.The question of when to trust your gut(直觉)and when to test your ___43___—whether to think fast or slow, in the language of Daniel Kahneman, a psychologist—___44___ in the office as much as it does in the savannah(大草原).Deliberative thinking is the feature of a well-managed workplace. Strategic changes and budget discussions are built on rounds of meetings, memos, formulas and presentations. Processes are increasingly designed to ___45___ instinctive responses. From blind screening of job applicants to using “red-teaming” techniques to pick apart a firm’s plans, precision ___46___ instinct.Yet instinct also has its place. Some decisions are more connected to emotional responses and inherently(固有的)less ___47___ to analysis. Does a marketing campaign capture the ___48___ of your company, say, orwould this person work well with other people in a team? In ___49___ customer-service situations, intuition is often a better guide to how to behave than a script.Gut instincts can also be ____50____. Plenty of research has shown that intuition becomes more unfailing with experience. In one well-known experiment, conducted in 2012, volunteers were asked to ____51____ whether a selection of designer handbags were fake or real. Some were instructed to operate on instinct and others to deliberate over their decision. Intuition worked better for those who owned at least three designer handbags; indeed, it ____52____ analysis. The more expert you become, the better your instincts tend to be.____53____, the real reason to embrace fast thinking is that it is, well, fast. Instinctive decision-making is often the only way to get through the day. Researchers at Cornell University once estimated that people make over 200 decisions a day about food alone. The workplace is ____54____ but a succession of choices, a few big and many small: what to ____35____, when to intervene, whom to avoid in the lifts and, now, where to work each day.41.

Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits bestaccording to the information given in the passage you have just read.(A)I had always been one of those quiet boys who preferred dreams to the real world. I was, in addition, absurdly shy, and therefore often mistaken for a fool, which upset me deeply. For nothing terrified me more than the prospect of correcting a false impression. Though I was often blamed by mistakes made by my classmates, I never dare to say a word in self-defense. I would simply go home to hide in a corner and cry. My greatest pleasure was to sit alone, reading, and let my thoughts drift away in the stories.My daydreams were in sharp contrast to real life; they were full of adventures and heroic deeds. They left marks on me. There was, for instance, a book about the history of the Roman Empire, in which an ambassador, while negotiating a treaty, was told that he was to accept the terms offered, on pain of death: his response was to plunge his arm into a fire and continue with his deliberations, in absolute calm. Inspired by his courage, I proceeded to test my own powers of resilience by plunging my own hand into the fire, only to burn my fingers badly. I can still see that ambassador, smiling calmly through his pain. Father hated my reading all the time, and sometimes he threw away my books. Some nights he refused to let me turn on the light in my bedroom. But I could always find a way, and after he caught me reading by the light of a string-wick lamp, he gave up and left me to it.There was a time when I tried my hand at writing; indeed, I even made a few little poems, but I quickly abandoned my efforts. No matter what I had bottled up inside me, I was extremely anxious about letting it out, and so my adventures in writing ended. I did, however, carry on painting. There was, I thought, no risk of revealing anything personal. I just took something from the outside world and brought it to life on paper. Sometimes I did hide some personal expression in it, but I made sure that it was visible enough to be seen and trivial enough to be ignored. The first time I showed my painting to my father, he was caught in silence for a while and then he breathed deeply, and said: “My son finally made something.” Then here I am, as a teacher at the Academy of Fine Arts, wondering how everything happened, from my daydreams to painting.56. The sentence “They left marks on me.” (in paragraph 2) means ________.A. daydreams did nothing but hurt the writer badlyB. daydreams influenced the writer's behavior in real lifeC. the writer had lasting memory of the books he readD. the writer couldn't distinguish books form reality57. The writer gave up writing because ________.A. it was not as interesting as readingB. he was too shy to reveal his inner worldC. he couldn't write good worksD. his father didn't like him writing58. Throughout the passage what can we learn about the writer's father?A. He was impressed with his son's paintingB. He didn't like the personality of his son.C. He was touched by his son's persistence in reading.D. He had a high expectation of his son in writing.59. The passage is mainly about ________.A. the power of readingB. the writer's adventurous daydreamsC. reflection on the start of a careerD. the efforts made to be painter(B)“Essential oils can have a major impact on your mood and health. When you apply an oil to your skin, it affects your physical state. When you inhale them, it affects your mental state,” says the “grande dame” of aromatherapy Jeanne Rose, author of The Aromatherapy Book: Applications and Inhalations.A few drops of eucalyptus on your skin will help heal a burn and smelling a pine tree might make you think of childhood Christmases. There are no rules for how to inhale oils. You can put a few drops on a tissue, or add some to water to spritz around the room or use in a diffuser(喷雾器)or vaporizer.Be very careful, however, when applying oils to the skin. Always dilute them in another oil, like palm, coconut or olive to prevent burns or allergic reactions.“A rule of thumb is 15 drops per one ounce of cream, oil or lotion,”says Sylla Sheppard-Hanger, the founder and director of Atlantic institute of Aromatherapy in Tampa, Florida.60. What kind of readers is likely to buy The Aromatherapy Book: Applications and Inhalations?A. Gardeners who provides raw materials for manufacturers of essential oils.B. Researchers dedicated to inventing new essential oils to keep people in good health.C. Common people hoping to improve health condition with essential oils.D.Psychotherapist seeking treatments for serious mental and physical disorders.61. What is the appropriate way of using essential oils?A. Spritz the oil directly around a room.B. Mix them with cream in proportion.C. Smell the fragrance from the bottle.D. Apply oils to treat skin allergy.62. The oils that can relieve your symptom of bad cold are ________.A. peppermint oilsB. conifer oilsC. citrus oilsD. spruce oils(C)By the end of the century, if not sooner, the world’s oceans will be bluer and greener thanks to a warming climate, according to a new study.At the heart of the phenomenon lie tiny marine microorganisms(海洋微生物)called phytoplankton. Because of the way light reflects off the organisms, these phytoplankton create colourful patterns at the ocean surface. Ocean colour varies from green to blue, depending on the type and concentration of phytoplankton. Climate change will fuel the growth of phytoplankton in some areas, while reducing it in other spots, leading to changes in the ocean’s appearance.Phytoplankton live at the ocean surface, where they pull carbon dioxide into the ocean while giving off oxygen. When these organisms die, they bury carbon in the deep ocean, an important process that helps to regulate the global climate. But phytoplankton are vulnerable to the ocean’s warming trend. Warming changeskey characteristics of the ocean and can affect phytoplankton growth, since they need not only sunlight and carbon dioxide to grow, but also nutrients.Stephanie Dutkiewicz, a scientist in MIT’s Center for Global Change Science, built a climate model that projects changes to the oceans throughout the century. In a world that warms up by 3℃, it found that multiple changes to the colour of the oceans would occur. The model projects that currently blue areas with little phytoplankton could become even bluer. But in some waters, such as those of the Arctic, a warming will make conditions riper for phytoplankton, and these areas will turn greener. “Not only are the quantities of phytoplankton in the ocean changing,” she said, “but the type of phytoplankton is changing.”And why does that matter? Phytoplankton are the base of the food web. If certain kinds begin to disappear from the ocean, Dutkiewicz said, “it will change the type of fish that will be able to survive.” Those kinds of changes could affect the food chain.Whatever colour changes the ocean experiences in the coming decades will probably be too gradual and unnoticeable, but they could mean significant changes. “It’ll be a while before we can statistically show that the changes are happening because of climate change,” Dutkiewicz said, “but the change in the colour of the ocean will be one of the early warning signals that we really have changed our planet.”63. What are the first two paragraphs mainly about?A. The various patterns at the ocean surface.B. The cause of the changes in ocean colour.C. The way light reflects off marine organisms.D. The efforts to fuel the growth of phytoplankton.64. What does the underlined word “vulnerable” in Paragraph 3 probably mean?A. Sensitive.B. Beneficial.C. Significant.D. Unnoticeable.65. What can we infer from the passage?A. Phytoplankton play a declining role in the marine ecosystem.B. Dutkiewicz’s model aims to avoid phytoplankton changes.C. Phytoplankton have been used to control global climate.D. Oceans with more phytoplankton may appear greener.66. What is the main purpose of the passage?A. To assess the consequences of ocean colour changes.B. To analyse the composition of the ocean food chain.C. To explain the effects of climate change on oceans.D. To introduce a new method to study phytoplankton.Section CDirections: Read the following passages. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.The explosion of new media, ranging from the internet to digital television, means that people working in advertising will have to come up with more ways to catch the public’s attention in the future. _________67_________ No longer will all members be watching the same programme: some will be watching different channels on their own TVs, surfing the net or doing both at the same time. The advertising industry will have to work “harder and smarter” to cut through the “mess” of the future with a wide range of new media, all competing to catch the consumers’ eyes.People have become more individual in their consumption of advertising. New technology has made experimenting with new forms of advertising possible. The monologue where the advertisement tells housewives that this is the washing powder they should buy is just a cliché (陈词滥调) now. _________68_________ There is, consequently, little hope of them surviving for more than another twenty years. A much closer relationship with the consumer is gradually being created.The definition of what constitutes advertising will expand well beyond the conventional mass media. Shopping environments will themselves become a part of the advertising process. Increasingly, they will exist not simply to sell goods, but also to entertain people and to make sure that they enjoy their time there. The aim will be to “warm” people towards these places so that they will return to purchase goods there again.In spite of these and other changes, it is highly unlikely that TV, print and radio will disappear altogether as advertising media. _________69_________ But other marketing strategies, such as public relations and direct marketing, will become as important as advertising. Advertising agencies will have to reinvent themselves. They will no longer be able simply to produce advertisements and then support these through PR,direct marketing or the internet. Instead, they will have to change the whole way they look at communication and start thinking about ideas which are not specific to one discipline._________70_________ Originality of thinking has always been in short supply. It will continue to be so in the future. But there will be increasing coston the advertiser’s ability to be imaginative and to think laterally about engaging the consumer in a broader variety of media.IV. Summary Writing (10分)Directions: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.Absent-mindedness“Most events of absent-mindedness—forgetting where you left something or wondering why you just entered a room—are caused by a simple lack of attention,” says Dr. Daniel Schacter, a distinguished psychologist and memory scientist. “You’re supposed to remember something, but you haven’t encoded it deeply.”“Encoding,” Schacter explains, “is a special way of paying attention to an event that has a major impact on recalling it later.” Failure to encode properly can create annoying situations. If you put your mobile phone in a pocket of a jacket, for example, and don’t pay attention to what you did because you’re involved in a conversation, you’ll probably forget where exactly you put your mobile phone. Your memory itself isn’t failing you. Rather, you didn’t give your memory system the information it needed.As many people accept, women have slightly better memories than men, possibly because they pay more attention to their environment, and memory relies on just that. Yes, visual cues can help prevent absent-mindedness. But be sure the cue is clear and available. If you want to remember to take a medication with lunch, put the pill bottle on the kitchen table—don't leave it in the medicine chest and write yourself a note that you keep in a pocket.Lack of interest can also lead to absent-mindedness. “A man who can recite sports statistics from 30 years ago may not remember to drop a letter in the mailbox,” says Zelinski, a scientist from New York University. There are many cases in life where women can remember prices of bags of different brands while they tend to forget the specific place where they put their bags.71._______________________________________________________________________________________ _________________________________________________________________________________________ _________________________________________________________________________________________ __________________________________________________________________________________________________________________________________________________________________________________ V.

2024年全国高考仿真模拟卷(二)语文
2024年全国高考仿真模拟卷(二)语文一、现代文阅读(2024·仿真模拟)阅读下面的文字,完成问题。
商周时期数量巨大、内容丰富的青铜器铭文,体现了中华文明独特的书写文化。
相比于其他文献,铭文能基本反映书写的原貌,因而对研究中国早期社会的历史、文化、思想等,有着重要的价值。
商周铜器铭文的书写之所以如此繁盛,除了物质条件的进步与社会需求等因素外,思想、情感层面的追求也是一个重要原因。
用文字进行书写是人类文明进步史上的大事,因为它代表着思想、情感的传播可以灾破时空的限制。
《墨子兼爱(下)》提到,今人不与“先圣六王”同时,却能了解其德行,“以其所书于竹帛,镂于金石,琢于盘盂,传遗后世子孙者知之”。
可见,古人早已认识到书写之于思想传承、文明演进的价值。
而在“传遗后世子孙”方面,铜器铭文(即所谓“金石”“盘盂”)更有着无可比拟的优势。
当古人认识到生命的有限性之后,青铜材质所具有的永存性,便寄托了他们对“永恒”的希冀,或者说是对生命“不朽”价值的追寻。
中国早期关于生命价值的体认,最有代表性的便是“三不朽”说。
《左传•襄公二十四年》记载晋范宣子与鲁叔孙豹讨论何谓“死而不朽”。
范宣子认为,自己家族自古至今皆有官职,这便是不朽。
但叔孙豹认为这只是“世禄”,并非不朽,真正的不朽应如鲁国臧文仲“既没,其言立”,即死后其言论仍能流传后世。
进而他便论述了“三不朽”的观念:“约闻之:‘大上有立德,其次有立功,其次有立言。
’虽久不废,此之谓不朽。
”即当时人们认为要在有限的生命中追求德、功、言三者的树立与传承,这样才能实现人生的崇高价值。
此种“生命价值观”后为儒家所继承并发扬,构成了中华文明的重要思想底色。
当然,“三不朽”的价值观并非《左传》所创,它应来自更久远的传承,并有逐步演化的过程,这一点便可从铜器铭文的发展中找到线索。
最早的铜器铭文非常简单,有的仅由一个或数个名词组成,稍复杂的也仅是一个主谓句。
商代晚期才有长篇铭文,其主要进步是能完整叙述一连串事件且有清晰的因果联系。

仿真模拟卷(一)(时间:40分钟满分:90分)一、选择题(每小题6分,共36分)1.下列化合物与其功能不符的是()。
A.自由水——细胞中的良好溶剂B.葡萄糖——细胞中的直接能源物质C.脂肪——细胞中的储能物质D.脱氧核糖核酸——细胞中的遗传物质解析葡萄糖是细胞生命活动所需要的主要能源物质,ATP才是细胞中的直接能源物质,B错误。
答案 B2.如图表示细胞凋亡过程,其中酶Ⅰ为核酸内切酶,能够切割DNA形成DNA 片段;酶Ⅱ为一类蛋白水解酶,能选择性地促进某些蛋白质的水解,从而造成细胞凋亡。
下列相关叙述,错误的是()。
A.凋亡诱导因子与膜受体结合,可反映细胞膜具有信息交流的功能B.死亡信号发挥作用后,细胞内将有新型蛋白质的合成以及蛋白质的水解C.吞噬细胞吞噬凋亡细胞时,利用了细胞膜选择透过性的特点D.酶Ⅰ能切割DNA分子而酶Ⅱ不能,表明酶具有专一性的特点解析细胞膜上的受体接受并传递信息,可反映出细胞膜具有信息交流的功能,A正确;从题干信息可知,细胞凋亡过程中有凋亡基因的表达以及蛋白水解酶水解蛋白质的现象,B正确;吞噬细胞吞噬凋亡细胞时,利用的是细胞膜的流动性,C错误;不同酶催化的底物不同,可反映出酶的专一性,D 正确。
答案 C3.下列关于生物科学研究方法的叙述不正确的是()。
A.将各种细胞器分离开时,常用的方法是差速离心法B.研究碳在代谢中的转化途径时,常用同位素标记法C.对数学模型进行检验或修正时,常用观察法或实验法D.调查土壤中小动物类群的丰富度,常用标志重捕法解析土壤中小动物因为个体较小,难以做标记,所以不能用标志重捕法,应用取样器取样法调查,所以D项错误。
答案 D4.下图1表示某二倍体动物的一个性原细胞经减数分裂过程传递基因的情况;图2表示该动物的性原细胞在正常分裂过程中,每条染色体上DNA含量和细胞中染色体组变化情况,下列有关分析正确的是()。
A.根据图1中生殖细胞的基因组成情况,可以肯定染色体数目变异发生在细胞①中B.在图1中,若不考虑基因突变,则一个精原细胞产生的精子中基因型只有2种C.图2左图中基因突变和基因的表达主要发生在A点以前D.图2中在BC段不会发生基因重组,CD段和GH段变化的原因相同解析图1生殖细胞中含有B和b,说明减数第一次分裂后期同源染色体未分离,A正确;不考虑基因突变,但是减数分裂四分体时期可能出现交叉互换,则一个精原细胞可能产生4种精子,B错;基因突变主要发生在DNA复制时期,在AB段,C错;图2左图可表示有丝分裂和减数分裂,其中BC段对应有丝分裂的前期和中期、减数第一次分裂及减数第二次分裂的前期和中期,故BC段可发生基因重组,D错。
答案 A5.下列关于全球性生态环境问题的描述,不正确的是()。
A.化学燃料的大量燃烧会导致温室效应、酸雨等环境问题B.引入外来物种不一定增加当地的生物多样性C.解决粮食短缺问题的一个重要措施是大量开垦草地等D.保护森林就是将合理利用森林资源和保护森林资源有机结合起来解析化学燃料的大量燃烧产生大量的CO2,会导致温室效应、酸雨等环境问题。
如引入外来物种在竞争中占优势地位可能会造成当地物种减少,不一定增加当地的生物多样性;解决粮食短缺问题主要依靠科技,大量开垦草地会破坏当地的生态平衡。
答案 C6.如图表示下丘脑参与人体稳态调节的三种方式。
下列相关叙述中,错误的是()。
A.抗利尿激素可以促进肾小管和集合管对水的重吸收,它是由下丘脑分泌并释放的B.如果甲状腺激素分泌过多,会抑制激素④和①(或②)两种激素的分泌C.胰岛中的B和C两种细胞虽然分泌的激素不同,但它们含有相同的核基因D.图中的A最可能是生长激素解析抗利尿激素是由下丘脑分泌、垂体释放的,A错误。
根据激素分泌调节中的反馈调节可知,甲状腺激素分泌过多会抑制垂体(分泌激素④)和下丘脑(分泌激素①或②)的分泌活动,B正确。
图中的B和C分别是胰岛B细胞和胰岛A细胞,虽然它们分泌的激素不同,但由于来自同一个受精卵,所以含有相同的核基因,C正确。
垂体可以分泌生长激素,所以图中的A最可能是生长激素,D正确。
答案 A二、非选择题(4小题,共39分)29.(10分)图1表示萌发小麦种子中发生的相关生理过程,A~E表示物质,①~④表示过程。
图2表示测定消过毒的萌发的小麦种子呼吸商(呼吸商指单位时间内进行呼吸作用的生物释放二氧化碳量与吸收氧气量的比值)的实验装置。
请分析回答:(1)图1中,催化过程①②的酶存在于细胞的________,物质E表示________。
(2)图2实验装置乙中,KOH溶液中放置筒状滤纸的目的是_____________。
(3)假设小麦种子只以葡萄糖为呼吸底物,在25 ℃下经10 min观察墨滴的移动情况,如发现甲装置中墨滴不动,乙装置中墨滴左移,则10 min内小麦种子中发生图1中的________(填序号)过程;如发现甲装置中墨滴右移,乙装置中墨滴不动,则10min内小麦种子中发生图1中的________(填序号)过程。
(4)在25 ℃下10 min内,如果甲装置中墨滴左移30 mm,乙装置中墨滴左移200 mm,则萌发小麦种子的呼吸商是________。
(5)为校正还应设置一个对照装置,对照装置的大试管和小烧杯中应分别放入________________。
解析本题考查呼吸作用基本知识和基本实验技能。
(1)图1中A、B、C、D、E分别是丙酮酸、CO2、[H]、O2、酒精。
①④③依次为有氧呼吸的第一、二、三阶段,①②分别是无氧呼吸的第一、二阶段,无氧呼吸的场所为细胞质基质,其中含有与无氧呼吸有关的酶。
(2)KOH溶液扩散到筒状滤纸上,增加吸收CO2的面积。
(3)葡萄糖做细胞呼吸底物时,有氧呼吸产生的CO2体积与消耗的O2体积相等。
甲装置中CO2不能被吸收,墨滴不移动,说明产生的CO2体积与消耗的O2体积相等,只进行有氧呼吸(过程①④③)。
乙装置墨滴左移是因为产生的CO2被KOH溶液吸收,有氧呼吸消耗氧气使装置内压强减小;若乙装置不动,说明不进行有氧呼吸,甲装置墨滴右移,说明进行无氧呼吸(①②)。
(4)乙装置墨滴左移200 mm是消耗的氧气的体积,与甲装置对照分析可知释放的二氧化碳体积为200-30=170(mm),所以呼吸商为170=0.85。
200(5)温度等物理因素也会引起气体体积的变化,校正时设置的对照装置中要排除生物呼吸作用的影响。
因是与装置甲作对照,故对照装置中大试管应放等量的煮沸杀死的小麦种子,小烧杯中的液体则和原装置中相同,为清水。
答案(1)细胞质基质酒精(2)增大吸收二氧化碳的面积(3)①④③①②(4)0.85(5)等量煮沸杀死的小麦种子、清水30.(11分)某雌雄同株植物花的颜色由两对基因(A和a,B和b)控制,A基因控制色素合成(A:出现色素,AA和Aa的效应相同),该花的颜色随细胞液pH 降低而变浅。
其基因型与表现型的对应关系见下表。
(1)B________________,BB和Bb的效应________(填“相同”或“不同”)。
(2)纯合白色植株和纯合红色植株作亲本杂交,子一代全部是粉色植株。
推测该亲本杂交组合可能为______________。
(3)为了探究两对基因(A和a,B和b)是否在同一对同源染色体上,某课题小组选用基因型为AaBb的粉色植株进行自交实验。
①实验步骤:第一步,粉色植株(AaBb)自交;第二步,__________________。
②预期实验结果(不考虑交叉互换)及结论:a.若子代植株花色为粉色∶白色=1∶1,则两对基因在一对同源染色体上;b.若子代植株花色为________________,则两对基因在两对同源染色体上;c.若子代植株花色为________________,则两对基因在一对同源染色体上。
竖线(|)表示相关染色体,请用点(·)表示相关基因位置,在下图圆圈中依次画出a、b、c三种情况中基因和染色体的关系。
(4)若上述两对基因位于两对同源染色体上,则粉色植株(AaBb)自交后代中,白色植株的基因型有________种。
解析(1)由表可知:A基因存在的情况下,没有B基因,花表现为红色,出现一个B基因,花表现为粉色,出现两个B基因,花表现为白色,说明B基因为修饰基因,负责淡化颜色,而且Bb和BB的效应不同。
再结合题干信息,该花的颜色随细胞液pH降低而变浅,说明B基因可降低细胞液pH,增强细胞液的酸性,进一步推测应该是B基因控制的蛋白质将H+运输进了液泡,那么该蛋白质只能是载体蛋白,位于液泡膜上。
(2)纯合白色植株和纯合红色植株作为亲本进行杂交,子一代全部是粉色植株,而粉色植株的基因型为A_Bb,纯合红色植株只能是AAbb,由此推测纯合白色植株的基因型为AABB 或aaBB。
(3)若两对基因(A和a,B和b)在两对同源染色体上,根据基因自由组合定律,则基因型为AaBb的个体的自交后代的基因型及比例为AABB∶AaBB∶aaBB∶AABb∶AaBb∶aaBb∶AAbb∶Aabb∶aabb=1白色∶2白色∶1白色∶2粉色∶4粉色∶2白色∶1红色∶2红色∶1白色,因此,红色∶粉色∶白色=(1+2)∶(2+4)∶(1+2+1+2+1)=3∶6∶7;当基因A、B在同一染色体上、基因a、b在同一染色体上时,则AaBb自交子代基因型及比例为AABB∶AaBb∶aabb=1∶2∶1,即白色∶粉色=1∶1;若A、b在同一条染色体上,a、B在另一条染色体上时,AaBb自交子代基因型为AAbb∶AaBb∶aaBB=1∶2∶1,即红色∶粉色∶白色=1∶2∶1。
(4)若这两对基因位于两对同源染色体上,则粉色植株(AaBb)自交后代白色植株的基因型有AABB、AaBB、aaBB、aaBb、aabb 5种。
答案(1)液泡膜将H+运输进液泡不同(2)AABB×AAbb(或aaBB×AAbb)(3)①观察并统计子代植株花的颜色和比例②b.粉色∶红色∶白色=6∶3∶7c.粉色∶红色∶白色=2∶1∶1圆圈中a、b、c三种情况中基因和染色体的关系如图所示(答案合理即可)(4)531.(9分)稳态是人体进行正常生命活动的必要条件,当机体处于不同的外界环境或生理状态时,体内的一些组织、器官、系统的功能也会发生相应的改变,但是人体并不会因此而失去稳态。
