What is the all or nothing response of local response?
It's just a way of saying that a neuron (or sensory cell) can either (only) respond or not respond (depending on the strength of the stimuli). Which is why your nervous system is said to be pulse modulated rather than amplitude modulated. OR A strong stimuli results in more pulses, not stronger pulses.
2 Define refractory period and differentiate between absolute and relative refractory periods?
refractory period is the interval between action potential , the absolute refractory period is the period in which second action potential can not be initiated but in relative refractory period the second action potential can be initiated by the more strong stimulus.
Is strong a common noun?
No, the word strong is an adjective, a word to describe a noun, for example a strong odor, a strong rope, a strong will, etc.

What can increase a strong stimulus?
threshold stimulus
Minimum level of stimulation required to trigger a neural impulse?
An action potential needs to occur to trigger the neurons but the action potential depends on whether a stimulus is able to bring the membrane potential to a certain level termed the THRESHOLD. This threshold is about -55 mV for most neurons, but the stimulus needs to bring the membrane potential to this certain level or it will not be triggered. Relating to the ALL-OR-NONE PRINCIPLE, which if the threshold is not acquired then an action potential will not occur but once a stimulus is strong enough to depolarize (making the inside of the cell less negative going from -70 mV to -55 mV) it will trigger. The resting potential is -70 mV which the stimulus needs to bring it up to -55mV.
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
What is an example sentence for exceptionally?

Flight or fight hormone?
The fight or flight response is a physical response; a strong stimulus or emergency causes the release of a chemical called nor-adrenaline (also called norepinephrine)
Similarities between systematic desensitization and flooding?
In both situations, a subject is voluntarily exposed to a noxious, anxiety-producing or otherwise aversive stimulus for the purpose of overcoming the subject's strong response to the stimulus. There may be other similarities, but no others are coming to mind.
What is fiction trigger?
A fiction trigger is an element in a book, movie, or story that evokes a strong emotional response in the audience or reader. It might include themes, scenes, or events that have the power to provoke emotional reactions such as fear, sadness, or excitement.

What is present in a vaccine to make white bloood cells create antibodies?
A vaccine usually contains a weakened form of the virus, strong enough to trigger your immune response but weak enough to be defeated by it.
When a neuron receives a stimulus that is very strong?
all or none fashion
Is conducting stimulus strong enough to generate a nerve impulse?
It depends on the strength of the stimulus. A threshold voltage has to be reached before the nerve can be stimulated.
