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:
Vegetative propagation
Explanation:
Vegetative propagation does not require seeds or spores. Instead, offspring grow from a part of the parent plant.
Answer:
C) Its physical appearance
Explanation:
The way I remember what phenotype is, is that both physical and phenotype begin with a p.
Hope this helped :)
Answer:
Velocity
Explanation:
This would be an example of velocity because it is both speed and direction.
Process converts energy from one form to another, some energy converts
