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:
The “recommended temperature limit” indicates limit of the temperature that is good for our world.
Explanation:
The temperature related to the “recommended temperature limit” means that in the graph there is a limit of temperature for our world's environment. if the temperature is between this limit, there is less or no adverse effect on our environment while on the hand, if the temperature exceeds from this limit, then it adversely affected our world because the concentration of carbondioxide gas in the atmosphere increases due to this increase temperature..
Answer:
D
Explanation:
Nutrition wise euglena is a producer, but locomotion wise it is classified as animal. Other example is chlamydomonas
Plants absorb<span> nutrients and </span>water<span> through their roots, but photosynthesis — the </span>process<span> by which </span>plants create<span> their fuel — occurs in the leaves. Therefore, </span>plants<span> need to </span>get<span> fluids and nutrients from the ground up through their stems to their </span>parts<span> that are above ground level. Just as animals, </span>plants<span> also contain vascular.</span>
