Solution
The correct options are A Heterogeneous C Diffuses slowly through animal membrane The statements (A) and (C) are true for colloidal solution. These are heterogenous (two phase) systems that diffuses slowly through animal membrane (parchment). These solutions do not settles by just gravity. Colloidal solutions show Tyndall effect (the particles scatter the light).
