Answer 19

One more question. This one is a little long.

Is blood clotting an example of a positive or negative feedback mechanism? Explain your answer based on the description of the mechanism.

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.

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.

Answer 20

I know blood clotting is positive feedback.
