Ques: Answer the following question given this paragraph: Pancreatic Secretion Regulation of pancreatic secretion is the job of hormones and the parasympathetic nervous system. The entry of acidic chyme into the duodenum stimulates the release of secretin, which in turn causes the duct cells to release bicarbonaterich pancreatic juice. The presence of proteins and fats in the duodenum stimulates the secretion of CCK, which then stimulates the acini to secrete enzyme-rich pancreatic juice and enhances the activity of secretin. Parasympathetic regulation occurs mainly during the cephalic and gastric phases of gastric secretion, when vagal stimulation prompts the secretion of pancreatic juice. Usually, the pancreas secretes just enough bicarbonate to counterbalance the amount of HCl produced in the stomach. Hydrogen ions enter the blood when bicarbonate is secreted by the pancreas. Thus, the acidic blood draining from the pancreas neutralizes the alkaline blood draining from the stomach, maintaining the pH of the venous blood that flows to the liver. Q: The entry of acidic chyme into the duodenum stimulates the release of what? Choices: - progesterone - gastrin - oxygen - secretin A:
Ans: secretin

Ques: Answer the following question given this paragraph: Competition within a species is called intraspecific competition. It leads to natural selection within the species, so the species becomes better adapted to its environment. Q: Competition within a species is called what? Choices: - reproducible competition - species competion - internal competition - intraspecific competition A:
Ans: intraspecific competition

Ques: Answer the following question given this paragraph: Most of the steps of cellular respiration take place in the mitochondria. Q: Where do most of the steps of cellular respiration take place? Choices: - ribosomes - nucleus - cytoplasm - mitochondria A:
Ans: mitochondria

Ques: Answer the following question given this paragraph: All that magma and gas pushing upward can make the volcano's slope begin to swell. Ground swelling may change the shape of a volcano or cause rock falls and landslides. Most of the time, the ground tilting is not visible. Scientists detect it by using tiltmeters, which are instruments that measure the angle of the slope of a volcano. Q: Instruments that measure the angle of the slope of a volcano are called what? Choices: - aberration meters - velocity meters - angle meters - tilt meters A:
Ans:
tilt meters
