Question

multiple answer 1 point
water moves via osmosis ______. (select all that apply)
from an area with a low concentration of other solutes to a higher one
from an area with a high concentration of other solutes to a lower one
through aquaporins
through the phospholipids

multiple answer 1 point
at equilibrium, select all that apply
there is no net movement of solute or solvent
there is not movement of molecules
the concentration of solute is homogeneous
solvent and solute molecules still move
solvent moves from high to low concentration

Explanation:

Osmosis is the diffusion of water across a semi - permeable membrane. Water moves from an area of lower solute concentration (higher water concentration) to an area of higher solute concentration (lower water concentration). Aquaporins are channel proteins that facilitate water movement. At equilibrium, there is no net movement of solute or solvent, but molecules still move randomly, and the solute concentration becomes homogeneous.

Answer:

For the first question:

• from an area with a low concentration of other solutes to a higher one

For the second question:

• there is no net movement of solute or solvent
• the concentration of solute is homogeneous
• solvent and solute molecules still move
