( 3 ) 請依其理念為嘉科實中設計一門教案，用以提升學生藝術鑑賞的不同層次與能力。(10 分)

( 2 ) 六個層次如何應用在作品的鑑賞學習上？(各 1 分、共 6 分)

 ( 1 ) 請問除了材料與環境層次之外的四個層次分別為何？ (各 1 分、共 4 分)

50. To study the function of the essential cytosolic Hsc70 genes in yeast, researchers constructed a shuttle vector in which a copy of the Hsc70 gene was ligated to the GAL1 promoter. The vector was then introduced into haploid yeast cells in which all four copies of the Hsc70 genes had been disrupted. Following introduction of the vector, you would expect that: (A) the yeast cells would grow on both glucose and galactose media. (B) the yeast cells would grow on glucose but not galactose medium. (C) the yeast cells would grow on galactose but not glucose medium. (D) on transfer to either glucose or galactose medium, the vector-carrying cells would eventually stop growing because of insufficient Hsc70 activity. (E) None of the above.

49. The enzyme telomerase uses mechanisms that involve: (A) repeating sequences at the telomeres. (B) having RNA oligonucleotides to act as templates as part of the enzyme. (C) allowing the end of the chromosome to get a little shorter each time a cell divides. (D) both repeating sequences at the end of chromosomes and RNA oligonucleotides to act as templates as part of the enzyme. (E) All of the above.

48. Which of the following descriptions about human metabolism is    correct   ?

(1) The Cori cycle is the synthesis of alanine from pyruvate in skeletal muscle and the synthesis of pyruvate from alanine in liver.

(2) Glucokinase in the liver acts in the conversion of liver glycogen to glucose 1-phosphate.

(3) The largest energy store in a well-nourished human is liver glycogen.

(4) Among its numerous metabolic effects, the protein leptin makes muscle and liver cells more sensitive to insulin.

(5) The hormone insulin decreases appetite. (A) 1 and 4. (B) 2 and 5. (C) 1 and 3. (D) 4 and 5. (E) 4 only.
