The discovery of numerous new species made it unfeasible to organize them all according to a hierarchy that reflected their complexity.
The potato does not increase in size because it is only a segment of the plant. Water absorbed from the soil is taken up by the roots and transported to other parts like leaves, but the potato itself does not directly absorb water from the soil.
Response:
2, 1, 4, 3.
Explanation:
The cell membrane potential can be described as the difference in electric gradient between the inside and outside of the cell. Ions play a critical role in creating this voltage difference.
Transmission of nerve impulses occurs through propagation. The cell maintains a resting membrane potential. The opening of sodium channels allows the inward movement of sodium ions, increasing the positivity of the membrane potential and causing depolarization. Subsequently, potassium ions begin to diffuse into the cell while sodium ions exit, resulting in the cell's repolarization.
Thus, the correct sequence of events is 2, 1, 4, 3.
