生活中的生物知识:

某人在家里卫生间发现大量的小蚂蚁,他怀疑自己患了糖尿病,于是去弄了一点药品回来,自己动手鉴定。请问他买回来的是什么药品()(根据课本知识回答)。

答案

参考答案:

NaOH和CuSO4

解析:

(1)碘是甲状腺合成甲状腺激素的重要原料之一,碘缺乏时,合成的甲状腺激素不足,反馈调节引起垂体分泌过量的TSH,刺激甲状腺增生肿大;Fe.Mn.B.Zn.Mo.Cu等元素在细胞中的含量很少,属微量元素;

(2)盐中的氯离子可使唾液淀粉酶的活性大大提高;

(3)暗红色的血红蛋白在氧浓度高的地方易与氧结合,形成鲜红色的氧合血红蛋白;血红蛋白是一种蛋白质,高温可使其失去活性;

(4)大量喝水后使胃液酸性降低,直接影响胃蛋白酶的催化活性;

(5)苏丹Ⅳ染液可将蛋黄中的脂肪染成红色;

(6)摄入大量的胆固醇,吸收进入血液后滞留在血管壁,使血管壁增厚,官腔变细;

(7)雌性激素可促进女性第二性征的出现;

(8)葡萄糖与斐林试剂反应产生砖红色沉淀,斐林试剂由NaOH和CuSO4配制而成。考点:本题考查的是生活中的生物知识。

The black and white bird came ashore on a beach in the south of the North Island nearly 4,000 miles away from its usual habitat. The creature’s astonishing journey was witnessed by a woman walking her dog as the two-foot bird waddled out of the water in front of her. She said, “It was out of this world to see it. It was this glistening white thing standing up on the sand and I thought I was seeing things.” The tale of the lost penguin is similar to the 2006 children’s film Happy Feet, in which a young penguin finds himself far from home during a voyage of discovery.

Conservationists believe it has completed an incredible journey for such a young bird — it is estimated to be around 10 months old. The most likely explanation for its appearance in New Zealand is the hunt for food. Experts said it may also have rested on an ice floe (浮冰) during its travels and was carried north for a great distance before it made a swim for dry land. Colin Miskelly, a curator of New Zealand Museum, said, “They can spend months at a time in the ocean and come ashore only to moult (脱毛,换毛)or rest.” Mr. Miskelly said the brave bird would have to find its way back south soon if it was going to survive. He said, “It is probably hot and thirsty and has been eating wet sand.” “It doesn’t realize that the sand isn’t going to melt inside it because they typically eat snow — their only liquid.”

New Zealand residents have been warned to give the bird a wide berth — it can inflict (予以) painful bites if threatened.
