A student put together the experimental setup shown above. The selectively permeable membrane is permeable to both types of solute molecules shown. 27. Do you expect the distribution of solutes on each side of membrane to change
over time? Explain.

28. Redraw the apparatus making an inference as to where molecules C and D will
be when it reaches equilibrium.

29. Once equilibrium is reached will the molecules continue to move? Explain.

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
