Answer: It allows the hormone to be degraded which is necessary for cellular metabolism
Explanation: The deactivation of hormonal signaling in our body is a very important mechanism of hormonal regulation. It is because it controls own hormone production and these hormones regulate various cell activities. The mechanism is known as a negative feedback mechanism. By this mechanism the hormone production back to its normal range. The best example to understand this is the thyroid gland regulation in our body. In brian, TRH (thyrotropin-releasing hormone) secreted from the hypothalamus which causes the stimulation of the pituitary gland which may lead to the production of thyroid-stimulating hormone (TSH). This TSH in order causes the stimulation of the thyroid gland to hormonal secretion. When the thyroid hormone level is very high then it provokes the negative feedback mechanism to decrease the secretion of TRH from the hypothalamus. After this level of TSH secreting from the pituitary is decreased. hence this mechanism the thyroid gland secretion is stopped.

Question 1 (1 point) Vasoconstriction occurs when epinephrine (adrenaline) binds to the a-adrenergic receptor on vascular smooth muscle cells. One way to treat high blood pressure is to administer competitive inhibitors that bind to this receptor. The Kd for binding of epinephrine to this receptor is ~UM. Based on the measured affinity (Kd) of the following drugs for the a-adrenergic receptor, which might be good candidates for high blood pressure medication? Drug A: Kd = 0.6 M; Drug B: Kd...
Drosopholia eye development is an example of cell differentiation directed by signal binding to a receptor tyrosine kinase (RTK). In this pathway, R7 photoreceptor development requires a receptor (SEV, sevenless), which is activated by binding to a plasma membrane bound signal (BOSS, bride-of-sevenless) displayed on the adjacent R8 cell Receptor activation leads to activation of RAS via two proteins, Drk (down- stream of receptor kinases) and Sos (son-of-sevenless). Activated RAS leads to activation of a phosphorylation cascade that activates the...

In what way is artificial selection different from natural selection? Question 1 options: A. There is no difference; both have caused evolution throughout the history of life on earth B. Artificial selection applies to changes in domestic animals only, while natural selection applies to all other species C. In artificial selection, human preference is the selecting force; in natural selection, environmental conditions are the selecting force. D. Artificial selection causes one species to change to another, while natural selection only modifies existing species. E. Artificial...
