护理入学考试生物
方法
- 说出这道题的主题:细胞结构、物质运输、细胞分裂、DNA 与蛋白质合成、遗传、生物分子、微生物或实验设计。
- 回忆关键规则:A–T 和 G–C,扩散由高浓度向低浓度,水向溶质更多的一侧移动,有丝分裂保持而减数分裂减半染色体数目。
- 对于杂交,先写出亲本的基因型,列出配子,并填好庞尼特方格再计数。
- 对于实验,标出自变量、因变量和控制变量,并问一问证据是支持还是仅仅提示了结论。
- 把每个选项与所问的问题对照,而不是只看它是不是一句真话。
公式表、每个专题的关键方法步骤和 8 道练习题,完整解答附在最后。
肩袖由冈上肌、冈下肌、小圆肌和哪块肌肉组成?
后纵隔内有哪个结构?
哪种 ABO 血型的血浆中同时含有抗 A 和抗 B 抗体?
肾小球出球小动脉收缩而入球小动脉不变时,往往会:
What do the spindle fibres do during cell division?
A plant cell is placed in a strong salt solution. Its membrane and cytoplasm pull away from the cell wall. What is this called?
What colour is phenolphthalein indicator in a basic solution?
Water is split as 2H₂O → 2H₂ + O₂. What volume of O₂ at STP (0 °C and 1 atm) forms from 2 mol of water?
答案: C · 肩胛下肌
SITS:冈上肌、冈下肌、小圆肌(teres minor)和肩胛下肌。大圆肌位置很近,但不属于肩袖。
答案: C · 食管
后纵隔内有食管、降主动脉、奇静脉和胸导管。心脏和升主动脉在中纵隔;胸腺在上纵隔和前纵隔。
答案: B · O 型
O 型血的人没有 A 或 B 抗原,同时产生抗 A 和抗 B 抗体。AB 型有两种抗原,但两种抗体都没有。
答案: C · 升高肾小球毛细血管压和 GFR
出球小动脉收缩把血液留在肾小球中,使其压力和 GFR 升高。血管紧张素 II 就是这样起作用的,这也是 ACE 抑制剂可能降低 GFR 的原因。
答案: A · They attach to chromosomes and move them to the poles
Spindle fibres are microtubules that attach to the centromeres. They line chromosomes up at metaphase and then pull sister chromatids (or homologous chromosomes in meiosis I) to opposite poles.
答案: C · Plasmolysis
Plasmolysis is the shrinking of the cytoplasm away from the wall of a plant cell as water leaves by osmosis. Crenation is the shrinking of an animal cell, lysis is bursting, and turgor is the pressure of a full cell.
答案: D · Pink
Phenolphthalein is colourless in acidic and neutral solutions and turns pink in basic solutions (above about pH 8–10). It is widely used in acid–base titrations.
答案: A · 22.4 L
2 mol H₂O gives 1 mol O₂ (ratio 2 : 1). At STP, 1 mol of gas occupies 22.4 L. The 2 mol of H₂ formed would fill 44.8 L.
