The repository of bile produced by the liver is one of the gallbladder's top priorities.
Bile is required to break down the body's fats and lipids, making it vital for digestion. In addition, it helps in the metabolism of bilirubin, which is produced when RBCs break down.
The gallbladder serves several essential purposes, including the following:
- The ability to empty and restock its bile reserves in response to intestinal hormones like cholecystokinin.
- To assist in controlling the bile's chemical makeup (the percentage of water, bile salts and more)
- To regulate the small intestine's bile flow.
- To contract (secreting bile into the biliary tract and duodenum)

Answer:
D. contact metamorphism
Explanation:
When there's a volcanic activity in certain area, very often it happens that there's magma that intrudes into the cold rock in the surrounding area. The intrusion of the hot magma into the cold rock layers causes big changes into the structure of the rocks. The high temperature and high pressure manage to influence the structure of the preexisting rocks, mostly on the places where the magma touches the cold rocks, leading to the formation of metamorphic rocks. This type of metamorphism is known as contact metamorphism.
