you hypothesize that slow fish who can't easily escape predators gain more from schooling fish than fast fish do. assuming that the effects of school size on competition for food are the same for both species, which of the models best illustrates how the costs and benefits of schooling will differ for fast fish as compared to slow fish

passive transport is a movement of biochemicals and other atomic or molecular substances across cell membranes without need of energy input. unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.

so, according to what that says, i believe it's hypertonic and hypotonic.

good luck!
