What are the three divisions (eras) of the phanerozoic eon?

x would be the most and the least would be y because there are more fruit   and seeds than flock z has insects

the question isn't complete here so i can't right an answer '_'

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!
