When does osmosis occur?
When two solutions, with different concentrations are separated by a semi permeable membrane. The flow will be from high concentration to low.
What is osmosis controlled by?
Osmosis is controlled by the permeability of the osmotic membrane and the equilibrium of the solutions on either side of the membrane. If the solutions have unequal concentrations or osmotic pressures, and the molecules in the solution can pass through the membrane, then the solutions will mix until both sides have equal concentrations. If the membrane is impermeable, then nothing will happen.
Components of the cell membrane constantly shift. The model describes this characteristic of the cell membrane.?
Yes, the Fluid Mosaic Model of the cell membrane describes this characteristic.
What best describes a cell that is isotonic for a substance?
The solute concentration is equal on both sides of the cell membrane
What does osmosis and active transport have in common?
Osmosis is the movement of water (solvent) over a semipermeable membrane - as long as there is a difference in concentrations of osmotically active substances (proteins for instance) on the two sides of the membrane, the water keeps moving to the side where concentration is higher, until there's no longer a difference. Water hence moves freely, passively, from a lower water concentration to a higher one. Active transport usually happens against an electrochemical gradient, i.e. energy (ATP) is used to pump a substance (solute) over a non-permeable membrane from lower to higher concentration. In this case it is the specific substance, not water, that moves over the membrane. The way of movement is different and the transported molecule is different in the two scenarios, but in both cases the molecule moves from a lower to a higher concentration with a membrane separating the two solutions.

Which term describes the the difference in the concentrations of a substance across cell membrane's?
Tonicity best fits the single word you are looking for. One side is hypertonic and the other will be hypotonic.
