Answer:
The correct answer is - the large cross-sectional area and greater length of the cytoplasmic core get less resistance than the smaller cross-sectional area.
Explanation:
The greater length and the large cross-sectional area of the cytoplasmic path or core get less resistance than the resistance of the current path which is the small cross-sectional area of axoplasm. This leads it to greater resistance than the resistance of the current path through the extracellular fluid.
Other than this there is also an unequal distribution of the ions that leads to the increase in potential difference as higher Na+ ions present in cytoplasm and high amount of K+ ion present in axoplasm.
Answer:
C - a geyser
Explanation:
When underground water and gases are heated by magma, they may shoot up to the surface as mud, water, or smoke, creating some very strange landscapes: Gases rise to the surface and form bubbling muddy pools of decomposed volcanic rock particles and water mixed together.
