Quizplus · Accepted Answer

The description clearly matches that of a hormone. Hormones are chemical messengers that are produced by specialized cells in one part of the body and released into the bloodstream. They then travel to other parts of the body where they have specific effects on cells and organs, including regulating developmental processes at different stages of life. Genes, proteins, and carbohydrates are not specific to regulating developmental processes, and pheromones are chemical signals used in communication between animals of the same species.
