hydrochloric acid & pepsin are enzymes secreted by cells in your stomach to digest proteins. the presence of partially digested protein in the stomach triggers the secretion of more HCl and pepsin. thus, once digestion begins, it becomes a self-accelerating process. this is an example of a. positive feedback b. negative feedback {Ans: a. positive feedback}when holding your arms out to the side at shoulder level, your fingers are _________ from your midline a. medial b. anterior c. proximal d. posterior e. lateral {Ans: e. lateral}place the events in correct order A: input about the controlled condition is sent to the control center. B: if needed, the control center sends output to an effector. C: effector can produce a response that helps maintain homeostasis. D: receptor monitors a controlled condition E-control center evaluates the value of the controlled condition compared to the set point. a. A, E, D, B, C b. D, A, E, B, C c. A, D, E, C, B d.
