高三第一轮复周测卷胞，C项错误：根据题表中数据可知，用浓度为25%的盐破溶液处理后，分裂期细胞数与观察细胞数的比值最高，说明该浓度更适合用于洋葱根尖细胞的解高，D项正确。【答案D3.存活因子是一种存活信号，它与细胞表面的受体结合后，启动细胞内部信号途径，抑制测亡发生，过程如图所示。下列叙述正确的是存活因子转录因子Bd-2基因周亡程序RNA蛋白激酶,。细胞凋亡注：→表示促进，表示抑制ABc-2基因仅存在于将要调亡的动物细胞中B.Bck-2基因的转录需转录因子，DNA聚合酶等的参与C.存活因子通过调控B2蛋白的合成来抑制细胞凋亡D.转录因子、ATP合成酶从细胞质进人细胞核通过0层膜【解析】B2基因不仅仅存在于将要调亡的动物细胞中，其存在于几乎所有的动物活细胞中，A项错误；Bl2基因的转录需转录因子、RNA聚合晦等的参与，B项错误；由题图可知，存活因子通过调控Bb2基因的表达，抑制细胞调亡，C项正确：转录因子从细胞质通过枝孔进入细胞核，通过0层膜，动物细胞中ATP合成的场所有细胞质基质和线粒体，细胞校中不能合成ATP,故ATP合成晦不进入细胞核，D项错误。【答案】C4.K1oho基因是一种与衰老密切相关的基因，它通过调控离子通道、信号通路或其他基因表达而发挥抗衰老、保护肾脏及心血管等作用。研究发现，Klotho基因缺陷小鼠寿命缩短了80%，而Klothe0基因过度表达后能够延长雄鼠30.8%、雌鼠19.0%的寿命。下列叙述错误的是A高等动物衰老的细胞内，Klotho基因的表达可能受到了抑制B衰老的细胞萎缩、体积变小，细胞核体积也变小，核膜内折，染色质收缩C.细胞代谢产生的自由基可能会攻击Kloth0基因，导致细胞衰老D.将更多的Klotho基因转入细胞后，可能不能完全阻止细胞衰老【解析】Klotho基因是一种与衰老密切相关的基因，它通过调控离子通道、信号通路或其他基因的表达而发挥抗衰老的作用，所以高等动物衰老的细胞内，Kloh0基因的表达可能受到了抑制，A项正确；衰老的细胞水分减少，细胞萎缩、体积变小，细胞核体积增大，核膜内折，染色质收缩，B项错误；根据分析可知，Koh0基因的表达可抵抗衰老，而细胞代谢产生的自由基可导致细胞衰老，可能是细胞代谢产生的自由基会攻击Kloh0基因，导致细胞衰老，C项正确；研究发现，K1oh0基因缺陷的小鼠寿命缩短了80%，而过度表达K1oho基因后能够延长雄鼠30.8%、雌鼠19.0%的寿命，说明细胞衰老不只与Kloh0基因有关，故将更多的Kloh0基因转入细胞后，不能完全阻止细胞衰老，D项正确【答案】B化5.图1表示细胞有丝分裂不同时期染色体数与核DNA数比例的变化关系；图2、图3分别是高等动细物甲，高等植物乙细胞有丝分裂的部分图像。下列叙述正确的是+染色体与核DNA数目比8AB7结构H微D五细胞分裂时期图1图2图3A图1中BC段进行核DNA复制，染色体数目加倍38【24G3ZCJ生物-R-必考-SX】

群落的水结构指群落的水配置状况或水格局，其主要表现特征是镶嵌性，不同林分密度下的植物种类存在差异体现了群落的水结构。【小问2详解】随林分密度的增大，白桦对阳光、养分等的竞争加剧，影响自身生长，导致均胸径减小。研究表明，人工造林时较为理想的林分密度是1200株hm2,此密度下白花均胸径最大，草本种数最多、灌木种数最多。【小问3详解】①碳元素在生物群落和无机环境之间以CO2的形式进行循环。植被中碳的去向与能量流动相辅相成，碳的去向为呼吸作用散失、流向消费者和分解者。林分密度为1000株hm2时土壤微生物分解能力增强，有机物分解速度快，导致土壤碳储量均较低。林分密度为1000株m2时密度过大净光合效率下降，植被碳储量降低，输入土壤的有机碳减少。适宜的林分密度能较好地实现土壤对碳的固存，提高了固定C02的能力，降低大气中C02浓度，缓解温室效应，这是生物多样性的生态学功能，这体现了生物多样性的间接价值。【小问4详解】人类活动往往会使群落演替按照不同于自然演替的速度和方向进行。不合理的人工林组成与结构及经营措施会导致一系列的生态问题，这主要违背了生态工程的整体、协调、循环、自生原理，最终影响碳汇林业的可持续性。21.下图是B细胞与辅助性T细胞(Th细胞)相互作用之后B细胞被活化的过程图。CD80/86是B细胞识别抗原后表达的蛋白，CD4OL是活化后的Th细胞表达的蛋白，BCR是B细胞表面的特异性识别抗原的受体，CD40和MHCⅡ是B细胞表面的组成性蛋白，CD28、TCR是Th细胞表面的组成性蛋白，请回答下列问题。B细胞Th细胞CD80/86CD28照网活化信号②BCR抗原加工、提呈MHCII TCRTh活化抗原Q活化信号活化信号①活化信号②CD40 CD4OLB细胞活●●●细胞因子(1)活化B细胞的第一信号是抗原在B细胞中加工形成的抗原肽，与MHCⅡ形成复合物，提呈给T细胞表面的,从而形成活化T细胞的第一信号。(2)由图可知，活化Th细胞和B细胞的第二信号分别是第21页/共29页
