D) cellular demands.
E) body temperature.

Question

Quizplus · Accepted Answer

Hormone concentration levels are typically regulated through negative feedback mechanisms, wherein an increase in circulating hormone levels triggers a response to decrease further release and secretion of that hormone. This helps maintain a stable balance of hormone levels in the body. Positive feedback may be involved in certain hormone release scenarios (e.g., during childbirth), but it is not the primary mechanism for regulating hormone concentration levels. Cellular demands and body temperature may also have some influence on hormone levels, but they are not the main control factors. The quantity of circulating hormone may be relevant to a certain extent, but it is ultimately subject to regulation through negative feedback.
