The process by which hormones are secreted is called:

Negation
Transmission
Endocytosis
Exocytosis

The correct answer is: Exocytosis

Hormones are secreted by endocrine glands through a process called exocytosis. This is when the hormone is produced in the cell and released into the bloodstream through the fusion of a vesicle with the cell membrane. Option A, negation, is the act of denying something and is not related to hormonal secretion. Option B, transmission, refers to the passing of information or signals and is not the process of secretions. Option C, endocytosis, is the opposite of exocytosis and refers to the uptake of substances into a cell. However, in this case, hormones are being released, not taken in, making option C incorrect.
