71.以下有關特定診斷試驗的敘述何者正確? (A)在疾病盛行率為80%的族群測試時,試驗的敏感性(sensitivity)會比在疾病盛行率為20%的族群測試時為高 (B)敏感性為60%的試驗,會比敏感性為70%的試驗,更可能發生假陽性結果 (C)對疾病盛行率為80%的族群測試時,試驗的陽性預測值(positive predictive value)會比在疾病盛行率為20%的族群測試時 為高 (D)降低特異性(specificity)可以減少假陽性結果

2.A shell explodes into two fragments, one fragment 25 times heavier than the other. If any gas from the explosion has negligible mass, then (A) the momentum change of the lighter fragment is 25 times as great as the momentum change of the heavier fragment. (B) the momentum change of the lighter fragment is exactly the same as the momentum change of the heavier fragment. (C) the momentum change of the heavier fragment is 25 times as great as the momentum change of the lighter fragment. (D) the kinetic energy change of the heavier fragment is 25 times as great as the kinetic energy change of the lighter fragment. (E) the kinetic energy change of the lighter fragment is 25 times as great as the kinetic energy change of the heavier fragment.

24.下列何者為引起家禽傷寒的病原? (A)Salmonella Typhimurium (B)Salmonella Heidelberg (C)Salmonella Gallinarum (D)Salmonella Kentucky

68.蛋白質純化可以根據溶解度、大小、電荷和結合親和力來純化。關於蛋白質純化,下列敘述何者錯誤?(A)蛋白質可以藉由半透膜(semipermeable membrane)透析,降低蛋白質溶液中的離子濃度 (B)蛋白質可以藉由凝膠過濾管柱(gel-filtration column)根據蛋白質大小分離,其中較小的蛋白質會較快通過管柱 (C)蛋白質可以藉由離子交換管柱(ion-exchange column),根據蛋白質淨電荷進行分離 (D)組胺酸標記蛋白質(His-tagged protein)可以藉由 Ni2+金屬親和性管柱(metal affinity column)進行分離
