1、所供应的溶液A和溶液B,其一为蔗糖,另外是转化酶.利用以下所供应的物料和一条透析管进行实验,以鉴别溶液A和溶液B.①本立德溶液;②二缩脲溶液;③大试管;④100毫升烧杯⑤1毫升移液管.描述你的方法.记录及解释所得的结果.保留所有测试样本,并加标记,以供评审.(注:透析过程需时约40分钟)(30分)2、将所供应的老鼠解剖,以展示泌尿生殖系统的其中一面(左面或右面).绘图显示所完成的解剖,并加标记.将解剖恰当地展示,以供评审.(注:不须解剖供应血液部分)(30分)3、样本C显示动物和静脉的横切面.(1)绘低倍标示图,以显示动脉和静脉的构造.(2)利用所供给的铜线,测定动脉和静脉管壁厚度的比例.列明计算的步骤.
1. The supplied solution A and solution B, one of which is sucrose, and the other is invertase. The experiment was conducted using the following materials and a dialysis tube to identify solution A and solution B.1 Ben Lid solution; 2 Urea solution; 3 large test tubes; 51 ml beaker with 51 ml pipette. Describe your method. Record and interpret the results. Keep all test samples and mark them for review. (Note: The dialysis process takes about 40 minutes. Minutes) (30 points) 2. Dissected the supplied mouse to show one side of the genitourinary system (left or right). The drawing shows the completed anatomy and marks. The anatomy is properly displayed for review. (Note: Don’t dissect the blood supply.) (30 points) 3. Sample C shows the cross-section of the animal and vein. (1) Draw a low magnification map to show the structure of the artery and vein. (2) Use the supplied Copper wire, determine the ratio of arterial and venous wall thickness. List the steps for calculation.
