Because that how is belonge
Answer:
<em>The correct option is d) once the electrical impulse reaches a certain level of intensity (its threshold), it fires and moves all the way down the axon without losing any intensity.</em>
Explanation:
In the field of biology, the all-or-nothing law can be described as a principle which focuses on the strength with which a nerve or muscle fibre responds to a particular stimulus, this strength being independent of the strength of the stimulus. The functioning of the impulse is just like the trigger of a gun. The more the force of a stimulus, the more will be the intensity of the nerve impulse.
There is evidence that Emanuel Swedenborg<span> first proposed parts of the nebular hypothesis in 1734.</span>[3][4] Immanuel Kant<span>, familiar with Swedenborg's work, developed the theory further in 1755, publishing his own </span>Universal Natural History and Theory of the Heavens, wherein he argued that gaseous clouds (nebulae<span>) slowly rotate, gradually collapse and flatten due to </span>gravity<span>, eventually forming </span>stars<span> and </span>planets.<span>[2]</span>
A week is the correct answer
Because they can usually predict mostly accurately up to 5-7 days which matches the answer for one week.
Hope that helps :)
