2.2.Which of the following hormones will NOT inhibit gastric function? A.GIP B.CCK C. Gastrin D.Secretin 2. Which of the following is an example of a negative feedback mechanism involved in gastric regulation? Choose all that apply. A.Entry of food into stomach causes the release of more secretions already present from the cephalic stage. B.As the pH decreases in the stomach, enteroendocrine cells are inhibited. C.Thinking about food causes the vagus nerve to excite the enteric nervous system and gastric secretions are released. D.CCK and secretin causes accessory organs to release secretions. E.GIP, CCK and secretin causes a decrease of gastrin release and decrease in stomach contractions. 3. In a healthy person, during what stage of gastric regulation would you except to find the highest levels of CCK in the blood? A.Cephalic B.Gastric C.Intestinal A.GIP B.CCK C. Gastrin D.Secretin 2.

The differences between the R and S strains of bacteria which Griffith used in his work. What makes the S strain smooth and which of the types is more dangerous when infecting an organism? 1.The R strain has a capsule which makes it appear rough; the R strain is more dangerous. 2.The S strain has a capsule that makes the outer edges smooth; the R strain is more dangerous. 3.The S strain has a capsule that makes the outer edges smooth; the S strain is more dangerous. 4.The R strain has an envelope that makes its edges appear rough; the S strain is more dangerous.. What makes the S strain smooth and which of the types is more dangerous when infecting an organism? 1.The R strain has a capsule which makes it appear rough; the R strain is more dangerous. 2.The S strain has a capsule that makes the outer edges smooth; the R strain is more dangerous. 3.The S strain has a capsule that makes the outer edges smooth; the S strain is more dangerous. 4.The R strain has an envelope that makes its edges appear rough; the S strain is more dangerous.

Question In the experiments of Avery, MacLeod, and McCarthy, which of the following was the key to unlocking the mystery of the “transforming principle.” 1.When DNA in the mix was removed and then put into R strain cells, the R strain cells became the virulent type. 2.This group did not study the transforming principle. 3.When the DNA in the bacterial mixture was isolated and put into the R strain cell, the R strain cells were transformed to the virulent type. 4.Only proteins from the mixture were needed to turn R strain cells into the virulent type. 1.When DNA in the mix was removed and then put into R strain cells, the R strain cells became the virulent type. 2.This group did not study the transforming principle. 3.When the DNA in the bacterial mixture was isolated and put into the R strain cell, the R strain cells were transformed to the virulent type. 4.Only proteins from the mixture were needed to turn R strain cells into the virulent type.
