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.
Answer:
decrease
Explanation:
if the producer is destroyed then all the others are dead
Definitely hypotonic. isotonic wouldn't change weight and hypertonic would lose weight.
Time is scare is the economic concept this dilemma demonstrate.
<h3>Why Time is scare?</h3>
The time is scare because there is an over lap between the team sport or doing the music instruction. This demonstrates that there is not enough time to meet demand.
Two of the tasks require more time than is available. Both team sports and music courses cannot be played because of the lack of time.
Although there is a strong need for time, two things cannot happen at once. The need for time is great, but there is nothing one can do about it; she must choose between the two options presented.
