Answer:
Energy
Explanation:
Usually the inside of the cells is hypertonic to the extracellular matrix. This means there are more ions in the cell than outside. Therefore the cell requires energy to pump more ions into the cell against the concentration gradient. The sodium-potassium pump utilizes energy from ATP to pump Na+ and K+ ions 'uphill' into the cell.

As the vast Pangea continent broke apart due to tectonic
movements, the movement of animals was restricted to their continent hence gene flow

population so as to adapt to the
new habitats. Some animals were unable to adapt
while others such as the reptiles, adapted well.
