Saturated and liquid at room temperature i believe
Answer:
c. 10
Explanation:
The pH scale ranges from 0 to 14.
0 is the most acidic
7 is neutral
14 is the most alkaline
10 is near 14
i think it's the independent variable
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.
