【練習題】【學測物理】91 補考單選63-35:概算能力 西元1808 年,道耳吞提出原子說,主張物質是由原子所組成,其後,亞佛加厥提出分子的概念。 然而原子與分子到底有多大?究竟一克的氫氣有多少個原子?用現在的說法,一莫耳的原子或分 「子是多少?這個問題,早已由美國著名的政治家也是科學家—富蘭克林,在西元1773年寫給朋友 的一封信中提及。他曾將一茶匙的油倒在湖面上,發現油會迅速擴張,直到蓋住約半畝的湖面就 不再擴張了。 XO- 假設油分子的形狀是正立方體,此實驗中一茶匙油的體積約為5.0立方公分,半畝湖面的面積約 為2.0 × 107平方公分,油的密度約為0.95克/立方公分,回答以下問題 (1)假設覆蓋在湖面的油層只有一個分子厚,則一個油分子的大小約為多少埃? (1 埃=10-8 公分)(A)10-2 (B)10-1 (C)100 (D)101 (E)10² (F)103 (G)104 (H)105 (2)湖面上約有多少個油分子?(A)1020 (B)1021 C)1022 (D)1023 (E)1024 (3)假設油分子的質量為每莫耳200克,根據富蘭克林的觀察作估算,下列何者最接近一莫耳油中 所含分子的數目?(A)1020 (B)1021 (C)1022 (D)1023 (E)1024 【答:(1)D (2)A (3)C】

劃螢光筆的這句不太懂，為何是用that?🙏

國中英語 關係代名詞 用來引導關係子句修飾名詞(後位修飾) , 被 修飾的名詞稱為「先行詞」,而關係子句又稱 為形容詞子句。不同種類的先行詞須用不同的 關係代名詞,文法:N+關係代名詞+ 子句。 ▶who:先行詞是「人」,如: The girl who is talking on the phone is my sister. (那個正在講電話的女孩是我姐 姐。) ▶which:先行詞是「事物」,如: The story which is told by my grandpa is very interesting.(我爺爺 說的那個故事很有趣。) ▶that: 1、一般狀況下取代 who/which,如: Ms he the boy that you are talking about? (他就是你們在談論的男孩嗎?) 2、先行詞同時包含人和人以外的事物,如: The man and his dog that are crossing the street helped the police catch the thief the other

想問一下第40題的d，不是只有生殖細胞的基因改變才可以傳給下一代嗎？ 謝謝🙏

B 109年指考 生物科 閱讀二 第8頁 共11 頁 自然界並不存在藍色的玫瑰。2004年,日本與澳洲的科學家利用RNA干擾(RNA interference, RNAi)技術,成功使玫瑰花的黃烷酮醇酵素(簡稱DFR)基因的表現量下降, 並同時轉殖入「能促使鮮藍色翠雀花素(Delphinidin)產生的酵素基因,因而創造了藍玫 瑰品種。這項RNA干擾技術是將基因DFR的基因片段轉殖入玫瑰,以產生雙股RNA;這雙 股RNA具有傳遞性,可以有效地在組織間移動,進而產生小片段的干擾RNA(簡稱siRNA), siRNA再與多個蛋白質形成RISC,RISC可進一步與DFR mRNA形成互補作用並切斷此 mRNA,導致無法表現DFR蛋白質,即基因靜默。當基因DFR靜默時,其他顏色的花青素 合成量會減少,而在翠雀花素累積的情形下,產生藍色的花色。依上文所述及習得的知識, 回答下列問題。 39.RNA干擾的技術,主要是造成目標基因表現的哪一步驟無法進行? (A)轉錄 (B)轉譯 40. 下列有關藍玫瑰培育成功的敘述,何者正確? (C)轉譯後的修飾 (A)RNA干擾的技術不具專一性,容易影響到其他相似基因 (B)只要引進單股的RNA即可有效率地造成花色的改變 (C)基因的靜默無法在細胞間傳遞 (D)藍玫瑰的特徵可以遺傳至下一代 (D)啟動子無法結合
