An important response mechanism in our bodies is blood clotting. the response loop is initiated when injured tissue releases signal chemicals that activate platelets in the blood. an activated platelet releases chemicals to activate more platelets, causing a rapid cycle and the formation of a blood clot. a)is blood clotting an example of a positive or negative feedback mechanism? explain your answer based on the description of the mechanism. b)blood clotting must happen quickly in order to be useful to the body. explain how this type of feedback mechanism is useful for accelerating the clotting process. c)imagine that a toxin in the bloodstream denatures the molecules that signal for platelets. predict how this would affect this feedback mechanism and the person’s body as a result.
