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。
1公式与方法
护理入学考试化学
方法
- 找出已知和所求：粒子、公式、状态变化、浓度、pH 或质量。
- 利用元素周期表：原子序数给出质子数，族给出价电子数和常见的离子电荷。
- 只用系数来配平方程式，逐个元素配平，最后配氧和氢。
- 对于量的计算，按质量 → 摩尔 → 摩尔比 → 摩尔 → 质量的路径，溶液则用 M = mol/L 和 C₁V₁ = C₂V₂。
- 记住 pH 是对数标度：一个单位相差 10 倍。

1.人体解剖学
答案: A · 输卵管壶腹部
为什么是这个答案
受精通常发生在输卵管壶腹部。胚胎随后移行到子宫着床。
答案
A · 输卵管壶腹部
2.人体解剖学
答案: C · 其内脏神经与脐部皮肤一样在 T10 进入脊髓
为什么是这个答案
来自中肠结构的内脏痛牵涉到脐周的 T10 皮节。当壁腹膜发生炎症时，疼痛便定位到右髂窝。
答案
C · 其内脏神经与脐部皮肤一样在 T10 进入脊髓
3.人体生理学
答案: A · 刺激肝脏的糖原分解和糖异生
为什么是这个答案
由 α 细胞分泌的胰高血糖素作用于肝脏，促进糖原分解，并由非糖物质生成新的葡萄糖。
答案
A · 刺激肝脏的糖原分解和糖异生
4.人体生理学
答案: C · 压力感受器反射使心率加快、血管收缩
为什么是这个答案
血液淤积在腿部，血压下降；压力感受器发放减少，几秒内交感活动增强、迷走活动减弱，心率和血管张力随之升高。
答案
C · 压力感受器反射使心率加快、血管收缩
5.护理入学考试生物
答案: A · A group where everyone in the population has an equal chance of being chosen
为什么是这个答案
In a random sample, chance decides who is chosen, so the sample is more likely to represent the whole population. Convenience and volunteer samples can be biased.
答案
A · A group where everyone in the population has an equal chance of being chosen
6.护理入学考试生物
答案: D · The sample did not represent that group
为什么是这个答案
Results can only be applied confidently to people similar to those studied. Age and sex may change how a drug works, so the findings need to be tested in a more representative sample.
答案
D · The sample did not represent that group
7.护理入学考试化学
答案: B · Hydrolysis
为什么是这个答案
Hydrolysis uses water to break the bonds between monomers, as when enzymes break starch into glucose or proteins into amino acids. It is the reverse of condensation.
答案
B · Hydrolysis
8.护理入学考试化学
答案: D · It has one valence electron like group 1 metals, but it is a nonmetal gas
为什么是这个答案
Hydrogen has one electron, which explains its position in group 1, but it is a nonmetal gas (H₂) that usually forms covalent bonds, as in H₂O and CH₄. It is not an alkali metal.
答案
D · It has one valence electron like group 1 metals, but it is a nonmetal gas
