The map shows areas of upwelling climate scientist predict that upwelling may intensify along the western coast of the United St

Andreas93 [3]

Answer:

Option (A)

Explanation:

Upwelling usually refers to the rising up of denser, deep-sea cold water to the surface of the ocean, replacing the less dense warm air.

It takes place both near the coastal areas and in the broad open ocean.

The deeper cold water is highly rich in the valuable nutrients, and as they rise up they carry these nutrients and distribute them in the upper region of the ocean water body. The marine organisms are directly dependent on these nutrients, thereby helps in biological productivity.

Thus, the intense upwelling occurring in a particular area in the ocean signifies the abundance of marine species.

Hence, the correct answer is option (A).

Answer:

The correct answer is: fat in the small intestine.

Cholecystokinin, abbreviated to CCK, is a hormone produced in the small intestine that participates in digestion. Its secretion is stimulated by fatty acids in the small intestine (more specifically, in the duodenum) and by the introduction of hydrochloric acid.

Cholecystokinin has the functions to 1) contract the gallbladder so it releases the stored bile into the intestine, and 2) stimulate the secretion of pancreatic juice, which induces satiety.
