False. Neurons always fire the same amount.

How can you tell the difference between a stroke across the cheek and a slap across the face?
1. A light touch, such as a stroke on the cheek, generates a low frequency of action potentials. A firmer pressure, such as a slap, elicits action potentials that pass down the axon at a higher frequency. A second factor is the number of sensory neurons activated. A slap stimulates a larger number of pressure sensitive neurons than a stroke does.
Does strong stimuli cause the strength of action potentials to increase?
No, it doesn't become "larger" - the peak potential is always the same - it is a digital signal. Stronger stimulus will cause the nerve cell to fire more often - therefore stimulus strength is translated as action potential frequency.
What is high air resistance?
Air resistance is a friction force, the flow of air over a surface will cause friction and produce drag. Thanks
How does the action of chewing help the enzymes?
The action of chewing breaks the food down into smaller pieces, thus creating a larger surface area exposed to digestive enzymes. The larger surface area enables a larger amount of food to be digested at a given time. Maybe your parents were on to something when they told you to chew your food well.
The body's need for larger and larger amounts of a drug to produce the same effect?
tolerance
What is difference between silicon and germanium semiconductors?
Silicon has a larger bandgap energy than germanium, which contributes to higher junction potentials and ability to operate at higher temperatures.
Is 6.5X284 Norma a short action caliber?
No, 284 is larger than a short action can take.
Strong stimuli cause the amplitude of action potentials generated to increase?
Yes. ....Up to a point. There is a threshold the stimulus must surpass before creating a CAP (compound action potential). Anything below this threshold is called subthreshold. Once the stimulus is strong enough cause a CAP it is a stimulus threshold. At this point the CAP will continue to increase as the intensity of the stimulus increases (now termed suprathreshold) until a maximal stimulus causes a maximum response. Any stimulus stronger than the maximal stimulus is called a supramaximal and does not result in any larger a CAP than the maximum response caused by the maximal stimulus. source: http://www.unmc.edu/physiology/Mann/mann12.html
Why does the frog sciatic nerve give a graded response?
The frog schiatic nerve gives a graded response because the nerve is a bundle of axons and not a single axon (thus it does not show the all or none response of an axon-either generating an action potential or not). If one axon is generating an action potential then a small nerve impulse is witnessed, if all axons are simultaneously generating action potentials then a large nerve impulse is witnessed. Thus the nerve impulse is graded (it can be none, small, medium, large, larger, maximal).
