【評論主題】23.圖7是某分子的結構式,W、X、Y、Z代表四種不同的原子,已知此分子是組成蛋白質的基本單元之一。下列敘述哪些正確?(應選3項) (A)W為氮(B)X為氧(C)Y為碳(D)Z為氫(E)此分子有14個
【評論內容】
組成蛋白質的主要元素為碳、氫、氧、氮、硫。
其中W為五價,X為四價,Y為六價,Z為一價,因此可以得知:
W=氮N
X=碳C
Y=氧O或硫S
Z=氫H
由上得知(A)和(D)正確
而圖中W和Y旁的點點是未形成鍵結的價電子,共有14顆,因此(E)正確
得到正解(A)(D)(E)

【評論內容】
A 由於交流電源為變動的電場,故產生了變動的磁場,進而與電磁爐產生電磁感應,並產生感應電流,故增大電流將使變動磁場量值更大,進而產生更大的感應電流
B 由於永久磁鐵未產生變動磁場,故無應電流產生
C 直流電源並不會產生變動電場
D 在使用交流電的情況下,匝數愈多產生的應電流愈大
