Soooo... thanks for the free points. Also I really need brainliest please
Answer:
1. Potassium
2. increasing towards zero
3. hyperpolarization
4. voltage-regulated Potassium
Explanation:
Membrane potential can be defined as the difference in electric charges inside and outside of a cell. The resting membrane potential (RMP) occurs when there is no net current across the membrane and therefore the cell is in a non-excited state. At the RMP, sodium ions (Na+) are more concentrated inside the extracellular fluid (ECF) than inside the intracellular fluid (ICF), while potassium ions (K+) are more concentrated inside the ICF. The diffusion of K+ outside the cell triggers its hyperpolarization, by becoming the membrane potential more negative compared to the resting potential. As the potential nears +35 mV, the voltage-regulated potassium channels are open, thereby K+ ions leave the cell down its concentration gradient, while voltage-gated Na+ channels become saturated and inactivate.
The answer is D<span>. Cell walls are made of cellulose. Cell membranes are made of proteins and phospholipids

Answer:
I don't know correct answer but I think it is <em>night time</em> in b point.
Answer:
I believe the answer is A because if shrimp eat phytoplankton, and squid eat shrimp this should work. I am not positive but I hope this helps.
