I believe D because if the fertilizer had a concentrated source of nitrate (which plants do need) then when watering that can go into the ground water which is underground <span />
If i remember correctly asexual reproduction came first because without asexual reproduction the cells would not have been able to produce other cells so what few cells there were reproduced asexually and then it evolved onto sexual reproduction later in development
The water would come out the bucket in one direction which is downwards
Answer:
depolarization leading to action potentials
Explanation:
The voltage-gated Na+ channels are responsible for rapid depolarization phase of the action potential. Action potential generation require depolarization of neuronal membrane which is acquired by influx of sodium ions through voltage gated sodium ion channels. If the Na+ channels are blocked, there will be no influx of sodium ions to cause depolarization hence action potential will not be generated.
Answer:
Explanation:
-Sodium-potassium pump (exchange of sodium and potassium ions across cell walls)
-Amino acids moving along the human intestinal tract.
-Calcium ions moving from cardiac muscle cells.
-Glucose moving in or out of a cell.
-A macrophage ingesting a bacterial cell.
