The release of gastrin, which triggers the stomach to release pepsin
The release of secretin, which triggers the liver to release bile
The release of secretin, which triggers the stomach to release pepsin

Answers

The answer is The release of secretin, which triggers the liver to release bile.

Secretin is the hormone released from the duodenum. It signals the secretion of bile in the liver. Bile helps digestion of lipids in the stomach.
Through the process of elimination:
- Pepsin is a hormone that breaks down proteins to the smaller peptides. So, pepsin does not breaks down lipids of high-fat meal.
- Gastrin is a hormone that triggers the gastric glands to secrete hydrochloric acid and pepsinogen, inactive form of pepsin.

Final answer:

This integral part of the eye widens or narrows to allow more or less light to enter, respectively. The pupil's size is regulated by the surrounding muscle structure, the iris, which adjusts depending on the intensity of light present. Unlike the cornea and fovea, which have different roles, the pupil specifically controls light entrance.
