This is a digestive hormone released with secretin when food from the stomach reaches the first part of the small intestine. It is made by some of the cells lining the first part of the small intestine.
This is clearly homework, so you need to open your book and read it to get the answer. Wiki will not help you cheat. Time to get to work.

It is Litmus Paper.
If I am remembering my science classes correctly blue or black coloring indicated the presence of starch.
cholecystokinin also known as {CCK}
It is Cholecystokinin (CCK)
A hormone produced principally by the small intestine in response to the presence of fats, causing contraction of the gallbladder, release of bile, and secretion of pancreatic digestive enzymes

Microviili increase the plasma membrane surface area. They are generally found in absorptive cells. (e.g. intestinal cells)
Will give information of presence of blood, undigested food, and presence of intestinal parasites.

ANSWER IS: Gastric secretion can be stimulated before food has entered the mouth.A.Gastric secretion can be stimulated before food has entered the mouth.B.Gastric secretion is enhanced by very low pH (below a pH of 2)C.The presence of food in the stomach prevents hormonal control of gastric secretion.D.Vagus stimulation of the stomach results in decreased secretion of gastric juice.
because of it low pH(making it acidic), the duodenum (the first section of the small intestine) secretes cholecystokinin (CCK), which causes the gallbladder to secrete bile.
The presence of blood may indicate the presence of internal hemorrhoids, or there may be intestinal polyps present which can bleed periodically. Only a doctor using a scope can tell for sure what the problem is.

The digestive juices are the secretions of the digestive tract that break down food. They include saliva, gastric juice, pancreatic juice, bile, and intestinal juice. The digestive juices are secreted by different organs, vary widely in chemical composition, and play different roles in the digestive process. Each is constantly produced by the body in small amounts, but the presence of food as it passes through the digestive tract causes increased production and secretion.
