survey carried out three years ago，we can see a growing trend among old consumers，I believe this trend will continue(与三年前所进行的调查结果相比，我们可以看到老年消费者的消费趋势，我认为：这个趋势会继续上升)”，由此可以看出，Sam认为老年消费者的消费趋势将继续呈上升态势。故选项B 是正确答案。
Figure 4 describes the theoretical results expected: a ratio close to 1 or -1 (for a flip ratio) (with yellow color) should be observed at the spot corresponding to the cross-hybridizing gene (used as control) whereas the color at the spot corresponding to the tested gene (deleted gene ...

Biology Direct BioMed Central Hypothesis Open Access Diverse bacterial genomes encode an operon of two genes, one of which is an unusual class-I release factor that potentially recognizes atypical mRNA signals other than normal stop codons Pavel V Baranov*1,2, Bente Vestergaard3,4, Thomas Hamel...
Which of the following best describes how ribosomes will interact with other organelles within a cell? a) They will break down other organelles by secreting digestive enzymes. b) They will provide energy to other organelles through cellular respiration Which cell organelle is called the headquarters...
The disclosure which follows describes such molecules. It was found that nucleic acid molecules encoding the proteins of the invention were expressed in the presence of IL-9, but not in its absence. Hence, these molecules are, inter alia, "markers" for the expression or effect of IL-9 in ...
This example describes preparation of a cDNA library for expression cloning of muOX40-L. The cDNA expression library was made essentially as described in U.S. Pat. No. 4,968,607, the disclosure of which is incorporated by reference herein. Briefly, murine lymphoma cells from the line S49.1...
