Write the formula that forms when Gallium and Nitrogen bond. Look up the charge of the positive cation (metal) first.
Look up the charge of the negative anion (nonmetal) second.
Criss-cross those charges so you have a number of each atom in the formula that lets the overall charge cancel out.
Reduce subscripts if you can.
GaN
Ga3N3
Ga3N2
GaN2
Ga2N
GaN3

The labels are not given to represent but the correct answer would be one of these:

-Uses energy

- low concentration to high concentration movement

Explanation:

Active transport and passive transport both are transport methods of the molecules and substances in or out of the cell through the cell membrane. Passive and active transport has only one thing which is the movement of the substance through or across the cell membrane.

However, there are differences in these types of diffusion are:

Active Transport                                        Passive Transport

-Uses energy                                                - a form of diffusion

-Moves from low to high concentration    - from high  to low concentration
