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】

1/20=2/5=40%,F2植株的基因型及比例为AA：Aa:aa=3:4:1。(5)植株甲、植株乙均为隐性突变植株，若植株的花色受一对等位基因控制，则植株甲和植株乙进行杂交，子一代仍为白花，而实际将植株甲和植株乙进行杂交，F,均为红花植株，因此可推测该植株的花色（至少）受两对等位基因的控制，突变为植株甲和植株乙的隐性基因不是同一对等位基因。

13.D【解析】取纵坐标为1，计算K≈10，A项正确：Cs取代Rb反应的衡常数c(Cs)Ka=10,因此{TizO18}团簇对于Cs具有比Rb大的亲和力，D项错误。14.D【解析】碳碳双键、醛基都能与溴水反应，向丙烯醛溶液中滴加溴水，溶液褪色，碳碳双键和醛基均能使溴水褪色，不能说明丙烯醛中含有碳碳双键，A项不符合题意；溴乙烷和NaOH乙醇溶液共热，产生的气体中含有乙醇蒸气，乙醇、乙烯都能使酸性高锰酸钾溶液褪色，高锰酸钾溶液褪色不能说明有乙烯生成，B项不符合题意；将花生油与NOH溶液混合，充分加热后分层消失，是由于油脂在碱性条件下水解生成了易溶于水的高级脂肪酸钠和甘油，C项不符合题意。15.D【解析】有机物C为苯甲醇，和乙醇均属于醇类，但不是同系物，A项错误；有机物A为乙醛，碳原子有sp3、sp杂化两种，B项错误；乙酸苯甲酯可与氢氧化钠溶液反应，C项错误。16.C【解析】乙二胺和三甲胺[N(CH3)3]均属于胺，乙二胺分子中含有N一H键，乙二胺分子间可以形成氢键，三甲胺分子间不能形成氢键，所以乙二胺的沸点比三甲胺高，C项错误。17.(1)5s25p2(1分)；B(1分)(2)A(2分)(3)①3(2分)②sp2(2分)③N>O>C(2分)×343(④（是，72分：NXax02分）3【解析】(1)S元素与Si元素为同主族元素，位于第五周期，所以其价层电子排布式为5s25p;根据洪特规则，同一能级电子要优先以自旋相同的方式分别占据不同的轨道，所以该排布式违反了洪特规则。(2)[S(OH)。]2-中，O原子和H原子之间为ō键，也为极性共价键，Sn原子和O原子之间有。键和配位键，所以该物质中不含π键。(3)该物质结构中，每个N原子都含有一个双键，所以N原子的杂化类型为sp;根据第一电离能的变化规律：同一周期从左往右呈增大趋势，VA族与IA族反常，故第一电离能：>O>C。×34(4)根据均裤法，该晶胞中含有专个CSnS,则CSnS的密度为Nax(aX100)名·cm3。18.(1)三颈烧瓶（或三口烧瓶，1分）；B(2分)(2)使酯化反应向正反应方向进行，提高苯甲酸的转化率(2分)；油水分离器中水面保持稳定（或油水分离器中水层高度不变，2分）(3)水浴加热(1分)(4)除去硫酸和苯甲酸等酸性杂质(2分)；除去残留的水(1分)【高二化学·参考答案第2页（共4页）】·23-494B·

向下排空气法收集；吸收尾气时要防止倒吸，因此选用F装置。(2)浓硫酸、五氧化二磷是酸性干燥剂，氨气是碱性气体，氨气不能用浓硫酸、五氧化二磷干燥，应该用碱石灰或生石灰千燥，故选BD。(3)浓盐酸具有挥发性，挥发出的氯化氢和氨气发生反应生成氯化铵白色固体，故现象为产生白烟，有关化学方程式是NH3+HCI=NH4CI。(4)可将NH转化为NH3进行检验，具体实验方案为：取样，向该氨肥溶液中加入浓NaOH溶液并加热，将湿润的红色石蕊试纸置于试管口，若观察到红色石蕊试纸变蓝，则证明氨肥中含有NHt。(5)生石灰与水反应生成Ca(OH)2并放出热量。实验室利用此原理，向生石灰中滴加浓氨水，可以快速制取氨气。此方法属于固液不加热制取气体，应选的气体发生装置是c。
