Answer:
B. they are pumped by proteins that require ATP hydrolysis and when the electrical charge gradient repulses or attracts them
Explanation:
Hello,
Ions move in the direction opposite to that favored by the chemical concentration gradient when they are pumped by proteins that require ATP hydrolysis and when the electrical charge gradient repulses or attracts them because active pumping moves ions against their chemical concentration gradients and the Nernst equation describes how membrane potentials can yield electrical gradients to motivate ion movement.

In order to find your answer you need to be <span>measuring entropy, so you will be using the following formula:

They allow us to see further and are able to focus on light from distant object. This is done by refracting or reflecting the light using lenses or mirrors.
Answer is: there is 1,368·10²⁵ atoms of carbon.
N(C₃H₈) = 4,56·10²⁴.
From molecular formula: in one molecule of propane there is three atoms of carbon:
N(C) = 3 · 4,56·10²⁴.
N(C) = 1,368·10²⁵.
