Answer:
The sodium-potassium pump contributes to the resting membrane potential.
Explanation:
This is the stage in which the neuron is not depolarize. 3Na+ are pumped outside through the sodium channels, while K+ channels are open for2 K+ to enter the cells.After some time the Na+ channels closed up. However some K+ channels still leaks , so that K+ still escape out of the cells to the external environment ,which contains more of Na+. Therefore at this stage there are more Na+ outside the neuron compare to the inside the neuron. Therefore the inside of the neuron is negative , because more K+ are leaving the cells, leaving negatively charged anions inside, and the outside is positive due to more Na+ are outside, and because the K+ leaking outwards.
The regulation of the Na+ and K+ ions movements is regulated by sodium potassium pumps along the membrane of the neuron. if the potential at this stage is measured, it has a value of -70mv, and it is called membrane potential.

Answer:
Ball-and-stick models show the bonds between atoms, but not the relative sizes of the atoms. Space-filling models show the relative sizes of atoms, but not the bonds between atoms.
Explanation:
Chemically, it is hard to understand the complex structure and shapes of the atoms and molecules. For better understanding, scientists have different models that help show the molecules in different prospects. For example, ball-and-stick and space-filling models.
The ball-and-stick model shows the three-dimensional arrangement of atoms and bonds. This model has a limitation that the identification of atoms requires a key to color representations. This model also does not show the relative size of atoms.
The space-filling model shows a three-dimensional arrangement as well as the relative size between atoms. Bonding between atoms can sometimes be difficult to distinguish in this model.
