Water is moving across a membrane from solution a into solutionb. What can be inferred? Solution a must be pure water. Solution a must have a lower solute concentration than solution
b. Solution a must have a higher solute concentration than solution
b. Solution a and solution b must have the same concentration of solutes. Solution b must be pure water.

Answers

The answer is solution a must have a lower solute concentration than solution  b.

That is when water is moving across a membrane from solution a into solution b, then solution a must have a lower solute concentration than solution  b.

When solution a have a lower solute concentration than solution  b, then water moves across a membrane from solution a into solution b.
