Answer:
Outer Core of Earth
Explanation:
The outer layer of core of earth consists of iron as a major constituent. Due to internal high temperature and low pressure (as compared to the inner core) , the iron in this layer exists as liquid iron. Since the earth is rotating continuously on its axis, the liquid iron is also rotating thereby producing magnetic field. Due to magnetic field , this sphere of earth is known as magnetosphere.

Answer:
The correct answer is - The neuron's intracellular charge must get more positive to meet a certain thresh hold in order to depolarize. If the neuron does not hit that threshold, then the neuron will not fire
Explanation:
In neuroscience, the depolarization of neurons shows the all or none law which is also called as all or nothing response. It states that all action potentials have the same size and the potential or strength of a nerve cell does not depend on the stimulus strength as all are the same size.
If a stimulus reaches a particular threshold cell or fiber will fire so either it will fire or not cross the threshold this is all or nothing response or law and depolarization is an example of it.

The sympathetic is used to speed things up, stopping things like digestion in order to supply more blood to the heart and lungs, while the parasympathetic does the opposite; digesting food and working on internal things while the heart rate and breathing rate slow.
