Hi there!
A nonrenewable resource is when you use something once, it cannot be used again, natural gases is an example.
Using this information, C. Coal is your answer.
Hope this helped! ♥♥
Answer:
Concentration gradient
Explanation:
Concentration gradient of the ions across the membrane generates the membrane resting potential.
Concentration gradient means that there is unequal distribution of the ions on different sides of membrane. For example, the concentration of K ions is much higher within the cell then out of the cell. Opposite is with the Na ions. When ions move from the area of their higher concentration to the are with the lower concentration, we say they move down the gradient or diffuse (no energy required). On the other hand, movement of ions against their gradient means that this process requires energy and involves protein pumps.
You need to give all the information. if a car is going 100 mph and a train is going 40 mph then the car will get there first. But you need to provide all the information in order to get a valid answer
I believe you use the pH scale with comparing acids and bases.
I think the answer is the last option or D) but i think i am wrong
