1、二轮复习联考(一)全国卷 理综生物答案 第 1 页(共 3 页)2023 届高三二轮复习联考(一)全国卷理综生物参考答案1.C【解析】糖蛋白由内质网上的核糖体合成,需经过内质网和高尔基体的加工、折叠和修饰,A 正确;糖蛋白的功能与细胞间的识别和信息传递有关,B 正确;高温会破坏糖蛋白的空间结构,但不会破坏蛋白质中的肽键,因此仍可与双缩脲试剂发生颜色反应,C 错误;糖蛋白具有识别功能,因此细胞表面含有识别激素的糖蛋白,D 正确。2.D【解析】只有实验“低温诱导植物染色体数目的变化”需要在低温条件下培养根尖,A 错误;漂洗根尖使用的是清水,而不是体积分数 95%的酒精,B 错误;观察细胞时,应先在
2、低倍镜下找到分生区细胞,再换用高倍镜观察,C 错误;两个实验观察的均为根尖分生区的细胞,D 正确。3.C【解析】基因的转录需要 RNA 聚合酶的催化,不需要解旋酶,A 错误;一个基因控制合成不同的多肽链与转录后形成的前体 mRNA 的加工、拼接有关,B 错误;翻译过程是以成熟的 mRNA 为模板,tRNA 携带氨基酸在核糖体上进行脱水缩合形成多肽,此过程需要消耗能量,C 正确;人成熟的红细胞没有细胞核和各种细胞器,因此不会发生呼吸酶基因的表达,D 错误。4.B【解析】神经递质只能由突触前膜释放到突触间隙,该方式为胞吐,A 正确;神经递质 A 与 NMDA 结合后会引起大量 Na+内流进入细胞,
3、从而引起突触后神经元兴奋,B 错误;药物氯胺酮和神经递质 A 均能与 NMDA 结合,氯胺酮与 NMDA 的结合会阻止神经递质 A 与 NMDA 的结合,C 正确;氯胺酮可抑制 NMDA的功能,既抑制 NMDA 的识别,也抑制 Na+内流,因此静脉注射氯胺酮不会引起突触后膜动作电位的电位差增大,D 正确。5.D【解析】烟粉虱吸食植物叶肉的汁液,因此两者之间的关系是寄生,A 错误;能量传递效率指的是相邻两个营养级间的同化量比值,不是两个或两种生物间的同化量比值,B 错误;采用样方法调查烟粉虱的种群密度时,应做到随机取样,C 错误;茉莉酸属于化学信息,通过化学信息可以调节种间关系,D 正确。6.C
4、【解析】第二组亲本均为弯曲尾,后代出现了正常尾,说明弯曲尾对正常尾为显性性状,F1中雌雄个体表现型不同,说明控制该性状的基因位于 X 染色体上,因此控制弯曲尾的基因为 XA,A 正确;亲本中、个体的基因型均为 XaY,个体的基因型为 XAY,均为纯合子;根据第三组 F1中弯曲尾和正常尾比例为4:1,说明中含有纯合子,B 正确;第三组弯曲尾和正常尾的比值未出现典型的 3:1 或 1:1 比例,与亲本中既有纯合子又有杂合子有关,但该性状的遗传仍然遵循分离定律,C 错误;第二组 F1中雌性个体的基因型及比例为 XAXA:XAXa=1:1,雄性个体的基因型及比例为 XAY:XaY=1:1;F1产生的雌
5、配子中,XA:Xa=3:1,产生的雄配子中,XA:Xa:Y=1:1:2,F2中雌性弯曲尾中,XAXA:XAXa=3:4,因此雌性弯曲尾中纯合子的比例为 3/7,D 正确。29.(10 分)(1)叶绿体基质和线粒体(2 分)(2)有(1 分)Rubisco 酶催化的是一类化学反应(2 分)升高(增加)(1 分)CO2的浓度升高时,Rubisco 与 O2的结合减少,减少 C5的消耗,增加了有机物的生成(合理即可,2 分)(3)光呼吸增强能量损耗,避免高温对叶绿体的破坏(合理即可,2 分)【解析】(1)由题图可知,光呼吸发生的场所为叶绿体基质和线粒体。(2)Rubisco 酶具有专一性,原因是酶的
6、专一性指的是酶只能催化一种或一类化学反应,而 Rubisco 酶催化的是一类化学反应。CO2的浓度升高时,Rubisco 与 O2的结合减少,减少 ATP、NADPH 和 C5的消耗,即增加了有机物的生成。(3)高温干旱导致植物气孔关闭,CO2吸收减少,光呼吸为植物提供更多 CO2,从而促进光合作用的发生。二轮复习联考(一)全国卷 理综生物答案 第 2 页(共 3 页)且光呼吸增强能量损耗,避免了高温对叶绿体的破坏。30.(9 分)(1)神经递质和高血糖(2 分)(2)胰岛素不敏感型小鼠(1 分)注射一定量的阿司匹林溶液(1 分)正常小鼠和胰岛素不敏感型小鼠(1 分)注射等量的生理盐水(1 分
7、)血糖含量(1 分)实验组小鼠的血糖含量低于对照组胰岛素不敏感型的小鼠,与对照组正常小鼠的血糖基本相同(合理即可,2 分)【解析】(1)人类糖尿病无论是型还是型,多饮、多尿、多食是其共同外在表现。在体液调节中,高血糖可直接作用于胰岛 B 细胞,引起胰岛素分泌;在神经调节中,传出神经释放的神经递质也可引起胰岛 B细胞分泌胰岛素。(2)若要验证阿司匹林能恢复胰岛素的敏感性,使血糖恢复正常。实验组选取胰岛素不敏感型小鼠,对小鼠进行的处理是注射一定量的阿司匹林溶液,对照组选取正常小鼠和胰岛素不敏感型小鼠,对小鼠进行的处理是注射等量的生理盐水,然后放在相同条件下培养一段时间,测定小鼠的血糖含量。预期实验
8、结果:实验组小鼠的血糖含量低于对照组胰岛素不敏感型的小鼠,与对照组正常小鼠的血糖基本相同。31.(8 分)(1)生态系统的组成成分、食物链和食物网(营养结构)(2 分)PCB 为难降解的化合物,几乎无法为生物体提供能量(1 分)呼吸作用以热能形式散失(及未利用)(1 分)(2)在机体内浓度超过环境浓度的现象(1 分)PCB 不易被生物排出,积累在生物体内,下一营养级生物在取食时,PCB 沿着食物链逐级聚集(合理即可,2 分)全球性(1 分)【解析】(1)生态系统的结构包括生态系统的组成成分、食物链和食物网。流经该湖泊水体的主要能量中不包括 PCB 中所含的能量,原因是 PCB 为难以降解的化合
9、物,几乎无法为生物体提供能量。鱼类所同化的能量,除了图中表示的流向下一营养级、流向分解者的能量外,还包括在呼吸作用中以热能形式散失(以及未利用的能量)。(2)鱼从湖泊水体吸收并积蓄 PCB,使其在机体内浓度超过环境浓度的现象,称作生物富集。食鱼鸟中PCB 的浓度会高于鱼,原因是 PCB 不易被生物排出,积累在生物体内,下一营养级生物在取食时,PCB 沿着食物链逐级聚集,积累在食物链的顶端。PCB 可以通过水和生物迁移等途径扩散到世界各地,说明生物富集现象具有全球性的特点。32.(12 分)(1)易饲养、繁殖快、子代数量多、相对性状明显易于观察、染色体少(答出两点即可,2 分)只有GAL4 基因
10、和 UAS 序列同时存在才能呈现绿色荧光(2 分)(2)将 F1中绿色荧光翅个体相互交配得到 F2,统计 F2的表现型及比例(2 分)11(2 分)97(2 分)(3)绿色荧光翅无色翅=11(2 分)【解析】(1)果蝇常作为遗传实验的材料,原因是果蝇易饲养、繁殖快、子代数量多、相对性状明显易于观察、染色体少。由于只有 GAL4 基因和 UAS 序列同时存在才能呈现绿色荧光,亲本中只含有两个基因中的一个,因此亲本雌、雄果蝇的翅不表现绿色荧光。(2)若用基因 G 表示 GAL4 基因,A 基因表示 UAS,未插入两种基因的另一条同源染色体相应位置上的基因用相关小写字母 g 或 a 表示,不论亲本果
11、蝇的基因插入一对还是两对同源染色体,甲的基因型为 Ggaa,乙的基因型为 ggAa。欲判断插入基因的位置,可将 F1中的绿色荧光翅雌雄个体杂交,若雌果蝇细胞中外源基因插入到 3 号染色体上,则 F2个体基因型 GgAa:GGaa:ggAA=211,表现型之比为绿色荧光翅无色二轮复习联考(一)全国卷 理综生物答案 第 3 页(共 3 页)翅=11;若雌果蝇细胞中外源基因没有插入到 3 号染色体上,两对基因自由组合,故 F2中绿色荧光翅无色翅=97。(3)若绿色荧光蛋白基因插入了 3 号染色体,两对基因不能独立遗传。(2)中 F2的所有果蝇进行自由交配,根据配子法,F2产生的雌、雄配子 Ga:gA
12、=11,所以 F3的表现型之比仍然为绿色荧光翅无色翅=11。37.(15 分)(1)秸秆还田的玉米地中富含纤维素,更易获取纤维素分解菌(2 分)碳源、氮源、水和无机盐(2分)凝固剂(琼脂)(1 分)(2)以纤维素为唯一碳源(2 分)增加纤维素分解菌的浓度,以确保能够从样品中分离得到纤维素分解菌(2 分)(3)平板划线法(2 分)刚果红染料(2 分)发酵产纤维素酶(2 分)【解析】(1)由于秸秆还田的玉米地中富含纤维素,更易获取纤维素分解菌,因此从玉米地寻找纤维素分解菌。图、图的培养基中都含有的营养成分为碳源、氮源、水和无机盐,图不同于图的成分为凝固剂(琼脂)。(2)可在培养基中添加以纤维素为唯
13、一碳源的选择培养基,通过选择培养增加纤维素分解菌的浓度,以确保能够从样品中分离得到纤维素分解菌。(3)图采用的接种方法为平板划线法。为了鉴别纤维素分解菌,可在平板中添加刚果红染料,选取有透明圈的菌落,为了确定得到的为纤维素分解菌,还需要进行发酵产纤维素酶的实验。38.(15 分)(1)Ti 质粒上的 T-DNA 可转移 DNA,并将其整合到该细胞的染色体 DNA 上(2 分)限制酶和 DNA连接酶(2 分)能吸收周围环境中 DNA 分子(2 分)(2)含潮霉素的培养基(2 分)含有草甘膦抗性基因的愈伤组织(玉米细胞)(2 分)(3)一定激素和营养(2 分)生芽(2 分)生根(1 分)【解析】(
14、1)采用 Ti 质粒转运草甘膦抗性基因的原因是 Ti 质粒上的 T-DNA 可转移 DNA,并将其整合到该细胞的染色体 DNA 上。过程用到了限制酶和 DNA 连接酶。过程用 Ca2+处理农杆菌细胞,使细胞处于一种能吸收周围环境中 DNA 分子的生理状态,然后与重组质粒混合,完成转化作用。(2)在培育抗除草剂玉米的过程中存在两次筛选,第一次筛选利用含潮霉素的培养基,筛选得到含基因表达载体的农杆菌;第二次筛选可利用 GUS 基因表达产物进行鉴定,目的是获得含有草甘膦抗性基因的愈伤组织(玉米细胞)。(3)脱分化需要在一定激素和营养等条件的诱导下进行,由愈伤组织到植株的再分化过程中,先诱导生芽再诱导
15、生根,并且此过程每日需要给予适当时间和强度的光照。学科网(北京)股份有限公司2023 届高三二轮复习联考(一)全国卷2023 届高三二轮复习联考(一)全国卷英 语 试 题英 语 试 题注意事项:注意事项:1.答卷前,考生务必将自己的姓名、考生号等填写在答题卡上。2.回答选择题时,选出每小题答案后,用铅笔把答题卡上对应题目的答案标号涂黑。如需改动,用橡皮擦干净后,再选涂其他答案标号。回答非选择题时,将答案写在答题卡上。写在本试卷上无效。3.考试结束后,将本试卷和答题卡一并交回。考试时间为 120 分钟,满分 150 分第一部分 听力(共两节,满分 30 分)第一部分 听力(共两节,满分 30 分
