1.) Does the data in the table provide sufficient evidence of the value for the threshold potential? Why or why not? 2.) A student remarked that at 180 mV of stimulus, it is expected that 100 g mass is lifted by the muscle fiber. Do you agree or disagree? Why or why not? 3.) How would you modify this experiment so that the mass lifted by the muscle contraction continues to increase for every trial?

4.) A pin can be pressed against the skin lightly and elicit no response from the pain receptor. However, if the pin is jabbed into the finger, the pain receptor may be stimulated and the finger would quickly be withdrawn through a reflex arc.
Use what you know about threshold potential and the all-or-none principle to explain different levels of sensation (light touch or pain).
