Blood calcium must be tightly regulated to prevent health problems. In the case of low blood calcium, chemoreceptive cells within the parathyroid glands detect the drop in Ca2+. This signals the synthesis of the hormone parathyroid hormone (PTH). PTH enters the blood, inhibits the loss of calcium in the urine, and encourages osteoclasts and osteocytes to resorb bone and release calcium into the blood, leading to a return to homeostasis. Is this an example of negative or positive feedback? In this example, what structure is the receptor? What structure is the integrating (control) center? What structure(s) serve as effectors? List at least one example.

Ricаrdо wаnts tо study the аcademic perfоrmance of graduate students in the United States. First, he decides that he will study schools in only 15 states and he randomly selects those states. He then randomly selects 30 schools from these 15 states. Over a period of 3 months, Ricardo travels to these 30 schools and studies the academic performance of their students. Identify the sampling technique used by Ricardo in this scenario.
