If the amount of a hormone in blood becomes more than needed how does the body usually balance it?
Answer and explanation
Correct answer: By reducing secretion through feedback control
Homeostasis keeps internal conditions within suitable limits. In negative feedback, a rise in a hormone or its effect is detected by the regulatory system, which reduces stimulation of the relevant endocrine gland and lowers further secretion. Therefore option A describes the usual balancing mechanism. The other options are biologically impossible and do not regulate hormone concentration.
