1.护理预科数学(入学考试)
答案: x = 20
比与比例:比 a : b 比较两个量。比例中两个比相等,a/b = c/d,用交叉相乘求解:a·d = b·c。把一个量按 m : n 分配,就把它分成 m + n 等份;一方得 m 份,另一方得 n 份。
答案: C · Plants and algae that make food by photosynthesis
为什么是这个答案
Producers (autotrophs) make their own food using light energy. Herbivores are primary consumers, predators are higher consumers and fungi and bacteria are decomposers.
答案
C · Plants and algae that make food by photosynthesis

为什么是这个答案
活动的肌肉需要大量 ATP,所以肌肉细胞中布满线粒体,有氧呼吸就在其中进行。
答案
D · 线粒体
17.护理入学考试化学
答案: D · 使速率加快
为什么是这个答案
温度越高,具有至少等于活化能的碰撞越多,所以反应更快。浓度、表面积和催化剂也会提高速率。
答案
D · 使速率加快
18.护理入学考试化学
答案: A · Each carbon is covalently bonded to four others in a giant network
为什么是这个答案
Diamond is a giant covalent (network) structure. Melting it means breaking a huge number of strong covalent bonds, not just weak forces between molecules, so its melting point is very high.
答案
A · Each carbon is covalently bonded to four others in a giant network
