37.[生物一选修1：生物技术实践](15分)1。作为世界上最重要的长纤维作物之一，黄麻在全世界的产量和种植面积仅次于棉花，享有“金色纤维”之称，在麻纺工业中发挥了重要作用。请回答下列有关问题：(1)沤麻是获取黄麻纤维的重要步骤，主要是在潮湿环境中利用一些细菌的作用分解黄麻韧皮部的果胶，从而将麻纤维释放出来，以便于后续处理。实验小组尝试从收割后的黄麻地里分离出高效分解果胶的细菌，应选用以为唯一碳源的固体培养基来筛选目的菌。有同学建议先将土壤悬液接种到液体选择培养基中培养一段时间后再接种到固体培养基中进行筛选，这样做的好处是色继筛色。染液，以方便挑选目的菌株若要筛选纤维素分解菌，则需要在培养基中添加(2)小华同学在使用高压蒸汽灭菌锅对培养基进行灭菌时，压力达到设定要求，而锅内并没有达到相应温度，最可能的原因是净织内纥烟。培养基灭菌后，小华用平板划线法分离土壤浸出液中的目的菌，划线的某个平板培养后，第一划线区域的划线上均不间断地长满了菌落，第二划线区域的第一条线上无菌落，其他划线上有菌落。造成划线无菌落的不当操作可能有钓适走虹也因(答2点)。(3)分离出目的菌后，某同学尝试用海藻酸钠对目的菌固定化，以便于重复使用，结果凝胶珠难以成形，导致实验失败的原因可能是固定化细胞失败后，该同学又尝试分离目的菌中分解果胶的酶，他可以采用的方法有位场2花电径么是乱(答2种)。38.[生物选修3：现代生物科技专题](15分)腺病毒载体疫苗的全称是重组新冠病毒疫苗(5型腺病毒载体)，只需要接种1剂。针对新冠肺炎病毒的腺病毒载体重组疫苗是将刺突蛋白基因重组到改造后无害的腺病毒内，导人人体，在体内产生刺突蛋白，刺激人体产生抗体，其技术路线为：刺突蛋白基因→腺病毒基因表达载体→人体。陈薇院士团队联合开发的新型冠状病毒（腺病毒载体重组疫苗）的原理如图：RNA提取总逆转录，D八①法择性，S基因@，构建含S注人人或动基因的重物体内⊙S蛋白引起免病毒RNA扩增的DNA反应组腺病毒请回答下列问题：(1)改造后的腺病毒载体应具备的条件之一是具有,以便外源基因插入其中。(2)过程①所用的酶是TagDNA聚合酶，其作用是欲选择性扩增出以便根据这一序列S基因的DNA,前提是要有一段设计特异性的引物(3)过程②构建含S基因的重组腺病毒时，其S基因应插入腺病毒载体的之间(4)该疫苗是将S蛋白基因插人到改造之后的腺病毒基因组中，待腺病毒侵染人体后，可引发机体的免疫反应。请用文字和箭头写出腺病毒载体疫苗进入机体后产生抗体的过程：为了提高疫苗的安全性，常采用复制缺陷型腺病毒为载体，目的是(5)为了检验表达的S蛋白是否与病毒S蛋白有相同的免疫反应特性，可用S蛋白与新冠病毒肺炎康实验，进行检测。复患者血清进行这兴妙知生会国统一考试（冲刺卷）·理科综合（一）第12页（共12页）】
25.(20分)如图所示，固定斜面倾角为日，在斜面顶端垂直斜面固定一挡板。木板P放在16.可视为质点的两个小球P和Q用长度为L的轻质细线相连，P和Q处在空中同一位三、非选择题：包括必考题和选考题两部分。第22题~第32题为必考题，每个试题考生置（距离地面足够远）。若把P以速度1水平向北抛出，同时把Q以速度2水平向南都必须作答。第33题~第38题为选考题，考生根据要求作答。斜面上，恰好静止，木板上端到挡板的距离为d。小滑块Q放在木板P的下端，P和Q质量均为m,P与Q之间的动摩擦因数是P与斜面间动摩擦因数的2倍，系统处于静抛出，经过时间细线被拉直；若把P以速度，水平向东抛出，同时把Q以速度2水(一)必考题：共129分。止状态。一质量为2m的小木楔以平行斜面向上的初速度射人滑块且没有穿出，该过平向南抛出，经过时间2细线被拉直。下列判断正确的是22.(5分)小马同学在做“研究匀变速直线运动”的实验时，实验室老师为他准备了如下器材：程作用时间极短。已知P、Q与挡板的碰撞均没有能量损失，最大静摩擦力等于滑动A.>tB.t
