Aselectively permeable membrane divides a container in half. one half of the container, side a, is filled with a starch solution, while the other half, side b, is filled with an iodine tincture. starch is a large macromolecule that forms a milky white solution when dissolved. an iodine tincture contains very small iodide ions and is a brown solution. iodide ions turn dark blue when they react with starch molecules. after several hours, side a is dark blue, while side b is brown. which statement describes the diffusion of solutes through the membranea. the membrane excluded the iodide ions, but the starch molecules diffused through. b. both the starch molecules and the iodide ions diffused through the membrane. c. the membrane excluded both the starch molecules and the iodide ions .d. the membrane excluded the starch molecules, but the iodide ions diffused through.

Asubstance is held in an open container. its particles move past one another at random speeds but do not leave the container. heat is removed from the system, and the particles slow down. when enough heat is removed, the particles no longer have enough speed to overcome the weak attractive forces between them. when this happens, the substance enters its solid state. the process described above is known as .
