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.

Vascular plants that have seeds surrounded by fruit are called as Angiosperms.
<h3>
Explanation:</h3>
Plants that have specialized vascular tissues that carry materials from one part of the plant to another is a vascular plant. The two types of vascular tissue, xylem and phloem, help in transportation of water, minerals, and the products of photosynthesis throughout the plant. Two types of vascular plants that produce seeds are : Gymnosperms and Angiosperms.
Gymnosperms are plants whose seeds are not enclosed by a fruit. The seeds are unenclosed or present on the surface or leaves. These seed are configured as cones. E.g: Cedar, pine
Angiosperms are fruit-bearing flowering plants with their seeds enclosed inside a fruit or flower. E.g: Apple, Eggplant
I think the correct answer would be branching of leaf veins. It is the most common feature of plants which are susceptible to the herbicide mentioned above. It kills plants through changing how cells grow. Hope this answers the question.
Answer:
As the redeposited minerals build up after countless water drops, a stalactite is formed. If the water that drops to the floor of the cave still has some dissolved calcite in it, it can deposit more dissolved calcite there, forming a stalagmite.
