The axis is an imaginary line going through the earth so the way the earth is "tilted" would tell you,for example, if the northern hemisphere is tilting toward the sun, it will be summer in the northern hemisphere.
A possible Hypothesis probably .
DNA stands for Deoxyribonucleic Acid, so it's an acid
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.
It should be an explanation on what you wanna learn about in the experiment, it should be based on prior knowledge, it is also different from a prediction
