Answer:
The second one I I think I could be wrong not sure
Answer:
True
Explanation:
The soil compaction results in an increase of bulk density of soil which cause the particle to move closer to each other thus resulting in mass per unit volume.
it also reduces the pore percentage in the soil hence decrease the permeability of the soil. lesser the permeability of soil higher is the chances of stagnation of water.
Answer: option B is correct.
Explanation:
Okay let us fill in the gap in the question;
"In a resting state, sodium (Na+) "is at a higher concentration outside the cell and potassium (K+) is more concentrated inside the cell. During an action potential, the sodium levels INCREASE inside the cell''.
The answer is option B. The levels of sodium inside the cell increase because Sodium (Na^+) enters while the potassium (K^+) moves out of the cell and NOT that the sodium(Na^+) leaves/moves out of the cell. The Sodium(Na^+) outside the content of the cell is more positive than the the content of the cell, this will enhance the sodium ion(Na^+) to move inside the cell thereby INCREASING the sodium levels in the cell.
