Those would be oceans and lakes. Hope this helps and have a nice day!
Answer:
The inside is becoming positive.
Explanation:
The membrane potential may be defined as the difference in the electric potential between the outside and inside of the cell. This potential difference is important for the conduction of nerve impulse.
The depolarization of the cell occur due to the movement of sodium ions inside the cell. The depolarization of the cell changes the membrane potential from -70mV to +30mV. The inside of the cell become more positive than outside of the cell.
Thus, the correct answer is option (a).
Answer: Bottom layer of rock
Explanation:
The bottom layer is the layer of the deposition of the sediments in which sedimentation and cementation occurs to form the rocks. These rocks are formed at the lowest horizon of the soil profile. These rocks are also called bedrocks. The layer present above the rock are younger and the layer at the top is the youngest layer. The older layer at the bottom and the younger layer at the top. This phenomena is called law of superimposition.
Your answer is B, cell wall.
