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】
考点39》生态系统的物质循环、信息传递及其稳定性1.D解析:碳元素在生物群落与无机环境之间主要以CO2的形式循环,A正确;枯落物中的碳为有机碳,可经分解者转化为无机物,形成土壤碳,也可转化进入绿色植物体内,B正确;绿色植物的光合作用吸收CO2,故植树造林可以“抵消”碳排放,C正确;杉木人工林中的有机碳最少,不是“抵消”碳排放、实现“碳中和”的最佳选择,D错误。2.D解析:生态系统中的能量流动是逐级递减的,据此可推知甲是生产者,甲残留的DDT浓度为0.04ppm,进而推知该生态系统的水体中DDT的浓度小于0.O4ppm,A正确;由题意可知,DDT难以被降解而在生物体内蓄积,说明DDT在代谢中不易分解,具有生物富集作用,B正确;丁种群个体死亡后释放的DDT难以被降解,可能通过各营养级生物的富集再次进入丁种群,C正确;在生态系统中,生物所处的营养级越低,所获得的能量就越多,但处于同一营养级的生物获得的能量差异不显著,据此分析表中的信息可推知:该生态系统中的四个种群的能量流动渠道是两条食物链,即甲→乙→丁和甲→丙→丁,D错误。【易错点拨】DDT在代谢中不易分解,具有生物富集作用,因此含量越高说明该生物所处营养级越高,和营养级所含的能量成反比。3.D解析:信息传递在生态系统中的作用包括:生命活动的正常进行,离不开信息的作用;生物种群的繁衍,离不开信息传递;调节生物的种间关系,进而维持生态系统的衡与稳定,A正确。海龟的舌尖处有两条红色突起,它在捕食时,先张开口并让舌头来回摆动,这是一种行为,因此属于行为信息,其中红色突起需要通过光传递信息,属于物理信息,B正确。动物的特殊行为能够对同种或异种生物传递信息,称为行为信息,C正确。食物链的起点应为生产者,D错误。4.D解析:呼伦贝尔草原就是一种处于生态衡的系统,其生产一消费一分解的生态过程正常进行,A正确;负反馈调节使生态系统达到或保持衡与稳态,当生态系统遇到破坏或干扰时,对抗破坏或干扰使该草原恢复衡的调节机制是负反馈机制,B正确;处于生态衡的生态系统具有结构衡、功能衡和收支衡三大特征,故该草原处于生态衡时会表现为结构衡、功能衡和收支衡,C正确;春夏季,该草原物质和能量的输入一般大于输出,而秋冬季一般会输出大于输入,D错误。5.D解析:由图可知,甲生态系统的结构和功能曲线波动幅度较大,所以甲生态系统抵抗力稳定性较弱,乙生态系统抵抗力稳定性较强,A正确;若乙生态系统受到干扰的时间提前,干扰强度不变,乙生态系统恢复自身原状的周
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。
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
