Answer:True
Explanation:
Nerve impulse must reach a certain threshold in a neuron before action potential can be generated to intiate conduction of action potential.
Therefore if mutiple impulses are generated and these are not upto thresholds , no matter how strong the stimulI are-NO ACTION POTENTIAL WILL BE GENERATED.
THIS IS ALL OR NONE PRINCIPLE
The all or none hypotheses can be best explain with flushing of the water closet after using it. If required volume of water is not pumped into the water closet storage above, no matter how long the handle is push, FLUSHING WILL NOT TAKE PLACE.Thus the threshold volume of water must be met.
It seems that this question missed the choices which are as follows:
<span><span>A. </span></span>Positive impact of a density-dependent limiting factor<span><span /><span>B. </span></span>Positive impact of a hurricane<span><span /><span>C. </span></span>Positive impact of beavers in an ecosystem<span><span /><span>D. </span></span>Positive impacts of dams on society
The correct answer that best describes the given characteristics above which are water storage, clean energy and flood prevention is option D. Positive impacts of dams on society.
Do you have different answers that go with the question?
They are capable of renewing and dividing (multiplying) themselves for long periods of time, they are unspecialized, and they can give rise to other specialized cell types. Hope this helps!! :)
