My daughter Kelly is a cautious person. She needs to warm up to situations, and is hesitant to try new things. When with close friends, she becomes a leader who laughs loudly and chants, “Girls rule, boys drool.” But when that comfort zone is not around her, she is shy and nervous.
This has been challenging for me at times. “Shy” is not a word that I think has ever been used to describe me. But this bas been a year of firsts for my girl that has filled her with a new sense of confidence. This year she moved to lap lane in swimming where she was preparing for a swim team. This year she learned to ride a bike without training wheels. And this year she completed her first kids’ triathlon (三项全能).
On Saturday, with a thunderstorm coming soon and my son’s birthday party later in the day, we all went out in the dark of the morning for Kelly to participate in her first triathlon. We practiced transitions from swim to bike to run with her, we got all the equipment she'd need, and we kept talking about the race. But as we waited the two hours for the older kids to finish before her turn, she held my leg a little harder and told me she loved me a few too many times. She was nervous but trying to keep it together.
And then it was her turn. From the second she jumped into the water, my heart soared. My daughter transformed into the most confident human being I had ever seen. She dominated that swim, crushed that bike ride and ran to the finish with the biggest

天津市和平区高三生物第三次质量调查试题（含解析） 理科综合生物学科试卷 第Ⅰ卷 一、单项选择题（共6小题，每小题6分，共36分） 1.下列有关酶的叙述，正确的是（） A. 在线粒体的基质中存在着大量的分解葡萄糖的酶 B. 酶可被水解为氨基酸或脱氧核苷酸 C. 人 的造血干细胞和肌细胞中不存在相同的酶D. 以底物的种类作为自变量，可验证酶的专一性【答案】D 【解析】【分析】1、有氧呼吸和无氧呼吸第一阶段相同，发生的场所都是细胞质基质，线粒体中不能分解葡 萄糖； 2、酶的绝大多数本质是蛋白质，少数是RNA。酶的专一性可以用相同的底物，不同的酶来验证，也可以用相同的酶，不同的底物来验证；所有细胞中都有与呼吸作用相关的酶。【详解】葡萄糖的分解属于呼吸作用的第一阶段，发生的场所是细胞质基质，线粒体基质中不能分解葡萄糖，因此，线粒体基质中不存在大量分解葡萄糖的酶，A错误；酶的绝大多数本质是蛋白质，少数是RNA，因此，酶可被水解为氨基酸或核糖核苷酸，B错误；人的造血干细胞和肌细胞中都存在与呼吸作用相关的酶，C错误；酶的专一性，可以用不同的底物，同一种酶来验证，D正确；因此，本题答案选D。 2.下表是能量流经某种植食性动物时的情况，下列说法正确的是（）
200/J cm a? A. X表示的能量为2 40/J cm a? B. 流向第三营养级生物的能量至多为2 C. 该植食性动物同化的能量中有20%通过呼吸作用散失掉 D. 表中四个量之间没有一定的数量关系 【答案】B 【解析】 【分析】 1、某一营养级（最高营养级除外）同化的能量去向有：呼吸作用消耗的能量，流向分解者的能量，流入下一营养级的能量，未被利用的能量； 2、能量流动的特点是：单向流动，逐级递减。单向流动是指在食物链中，能量只能从低营养级流向高营养级，而不能倒过来流动；一般来说，在输入到某一个营养级的能量中，只有10%-20%的能量能够流到下一营养级。 【详解】同化量=摄入量－粪便量=530-330=200J/（cm2·a），同化量有两个去向，即同化量=呼吸消耗量+生物用于生长发育和繁殖的能量，即200=X+110，因此，X表示的能量为90 J/（cm2·a），A错误；流经某种植食性动物（第二营养级）的能量为200 J/（cm2·a），按最高的传递效率20%来计算，则流向第三营养级的能量至多为200×20%=40 J/（cm2·a），B 正确；该植食性动物同化的能量通过呼吸作用散失的百分比是：90/200×100%=45%，C错误；表中四个量之间有一定的数量关系，D错误；因此，本题答案选B。 3.下列关于配子基因型异常发生时期的判断，正确的是（）
