Which of the following is not an example of active transport? I. Facilitated diffusion II. Osmosis III. Diffusion
klasskru [66]
I. Facilitated diffusion is your answer. 
Active transport <span>is the movement of molecules across a cell membrane into a region of higher concentration, this process requires energy. Both osmosis and diffusion are passive transportations which means that they don't require energy.
Hope this helps!

Concentration cell based on the Ni2 -Ni cell reaction.
Alex73 [517]

Answer:

Explanation:

The missing diagram contained in this question is first attached in the image below.

The objective of this question is to determine how ions migrate when the cells are operating by assuming the solutions are composed of Ni(NO3)2.

From the information provided:

In this instance, the ions tend to move first from cathode to anode in terms of raising the concentration of Ni(2+) at the anode, resulting in the development of a dead cell. The initial concentration of [Ni(2+)] in the anode solution is 1.00 × 10⁻³ M, which gradually increases to 0.5 M, during which both the cathode and the anode possess the same concentration at the same point.

This causes Q(equilibrium constant) to equal  1 as well as log(Q) to equal 0, indicating that the cell is dead.

As a result, the cell will cease to operate, and nothing will migrate from the left to the right side.
