Which example represents an abiotic factor in an aquatic ecosystem?
Water lilies float on top of a pond.
O A population of bass is living in a lake.
O The pH of a lake is decreased by acid rain.
O Dragonflies feed on small insects near a pond.

the endomembrane system i think

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!
