※ 引述《slin (slin)》之銘言： : Adult female rats who have never before encountered rat pups : will start to show maternal behaviors after being confined with a : pup for about seven days. This period can be considerably shortened : by disabling the female’s sense of smell or by removing the scent-producing : glands of the pup. : Which of the following hypotheses best explains the contrast described above? 題意: 成年但還未接觸幼鼠的母鼠如果把他們和幼鼠關在一起的話大約七天會有母性的行為如果說把成年母鼠的嗅覺除去或是把幼鼠分泌氣味的拿掉母鼠會快一點去照顧幼鼠 (就是說不用到七天就會去發揮母愛了) contrast: 有嗅覺七天 <--->沒嗅覺較短時間我的看法是對比在這拉可以聞到幼鼠的氣味應該會較快發揮母愛為啥還拖比較久 --->找解釋 : (A) The sense of smell in adult female rats is more acute than that in rat : pups. 成年母鼠的嗅覺較敏銳 ...無關如果較敏銳的話為啥拿掉嗅覺後反而可縮短 : (B) The amount of scent produced by rat pups increases when they are in the : presence of a female rat that did not bear them. 幼鼠分泌的氣味會增加 ...無關如果可以解釋的話為什麼去除掉母鼠的嗅覺器官和幼鼠的scent-producing glands 反而可縮短呢 : (C) Female rats that have given birth are more affected by olfactory cues : than are female rats that have never given birth. 有生過的母鼠較易受影響題目沒有拿生過和未生過的做比較 : (D) A female rat that has given birth shows maternal behavior toward rat pups : that she did not bear more quickly than does a female rat that has never : given birth. 同C : (E) The development of a female rat’s maternal interest in a rat pup that ~~~~~~~~~~~~~ 發展和時間相關要注意 : she did not bear is inhibited by the odor of the pup. ~~~~~~~~~~~~~ 聞到味道了所以受限那聞不到味道變快了 (好像可以理解) 概念大概是成年母鼠聞到幼鼠散發的氣味知道他不是自己的小孩所以不會去照顧所以時間被拉長了聞不到味道不知道是不是自己的小孩看到幼鼠就先去照顧了 : 答案是E : 這題我跟我朋友討論了很久,我們對於題目的意思,以及問題中的"contrast",還有正確 : 答案為什麼是E,都有所疑惑,是不是可以請版友不吝告知,謝謝大家了,,, -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 122.124.100.56
