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 <u>increase </u>inside the cell.
During an action potential, the potassium level inside the cell decreases, and the sodium level inside the cell increases. That is to say, there is an outflow of potassium and an inflow of sodium ions.
Action potential usually occurs when an electrical signal disrupts the balance of Na+ and K+ within a cell membrane, briefly depolarizing the concentrations of each.

Answer:
This question lacks options, however, it can be answered based on general understanding of forest layers.
The difference in photosynthetic rate is as a result of the amount of sunlight received by plants in the canopy and the forest floor.
Explanation:
Canopy of a forest refers to the collection of the crowns of trees found above the ground layer of a forest while the forest floor is the ground level of the forest. Plants that grow in the canopy are directly exposed to sunlight and receives most of the light from the sun while plants that grow in the forest floor are least exposed to sunlight as the crowns of the plants in the canopy covers/masks them.
Based on this, the rate at which the plants in the canopy layer photosynthesize will he higher than that of the plants in the forest floor because the amount of sunlight is a determinant of the photosynthetic rate.
