Answer: The mechanism for this process is osmosis.
Explanation: We are given a beaker having 2 compartments, one having 25% glucose solution and one having 5% glucose solution. So, the transport of solution will happen from compartment A to compartment B by the mechanism of osmosis.
Osmosis is a process in which solvent particles move from the compartment having higher concentration to lower concentration through a semi-permeable membrane.
This mechanism will be followed for the transport mechanism from compartment A to compartment B.
