Hоmeоstаsis refers tо the аbility of the body to mаintain internal environment relatively stable despite fluctuations in the external environment. It is one of the central themes in life sciences and it depends on biofeedback loops. Below is biofeedback loop demonstrating homeostasis of thyroid hormone secretion. A. What type of a hormone is a thyroid hormone: protein, steroid, or amine? Explain your reasoning. (1 pts.) B. Based on the above image, what type of biofeedback loop does the regulation of thyroid secretion follows: positive or negative? Explain your reasoning. (1 pts.) C. What mode of regulation does the secretion of thyroid hormone follows: hormonal, neuronal, or humoral? Explain your reasoning. (1 pts.) D. Thyroid hormone is responsible for regulating basal metabolic rate. An increase in thyroid hormone in the body above the amount naturally produced would increase metabolic rate and lead to decrease in weight. Suppose a person with a normal thyroid gland took thyroid pills. The amount of artificial thyroid hormone she is taking via pills is the same as the amount produced naturally by her thyroid gland. Would she lose weight? Why or why not? (1 pts.)
