1.Consider the energy budgets for a human,an elephant, a penguin,
a mouse, and a snake. The _______ would have the highest total annual
energy expenditure, and the _____ would have the highest energy
expenditure per unit mass.
(A) elephant;human
(B) elephant;mouse
(C) penguin;mouse
(D) human;penguin
(E) mouse;snake
答案给E，但应该是B吧?
2.Which of the following animals uses the largest percentage of
its energy budget for homeostatic regulation?
(A) a hydra
(B) a marine jelly(an invertebrate)
(C) a desert bird
(D) a desert insect
(E) a snake in a temperate forest
答案是E
跟上一题一样的疑问，为什麽不选内温哺乳类的(C)，而是外温的蛇(E)
3.The wolf, his coat glowing in the early spring sunshine,sat atop

(A)heat evaporated away on the gentle breeze

1F：→ Mario3:第3题我觉得是文字叙述的对错问题. 1.有皮草热不易蒸发散失 06/01 15:52
2F：→ Mario3:2.热因蒸发而自口散出(而非传导) 3.体热传导到石头(非蒸发) 06/01 15:54
3F：→ Mario3:4.辐射确实有发生 5.自阳光接收热为辐射(非传导) =>故选D 06/01 15:55
4F：→ Mario3:另外:狗据说不会流汗.所以不是蒸发散热.有风应是指对流散热 06/01 16:03
5F：→ Mario3:但是有皮草就阻挡了对流(convection)效果 06/01 16:04
6F：→ Mario3:...这样说好像也不太对.有毛是保暖不一定能防风 06/01 16:06
7F：→ fireunicorn:舌头... 06/01 16:22
8F：推 nashQQ:1,2题 答案给错了 你写的才是对的 不知错的答案来自何处? 06/01 17:03
9F：→ kilometer:疲倦的狼趴在岩石上娇喘,诱使人选B,我中计了 06/01 18:11
10F：→ kilometer:虽然radiate的量不多,但叙述正确 06/01 18:12
11F：→ kilometer:这是曾正的题库,1,2题大概是想误导故意给错的吧 06/01 18:14
12F：推 NDSHYELLOW:Mar 狗其实会流汗喔 不过确实不是主要散热方式 06/02 00:24
