Materials are able to move across a cell membrane through one of two methods: active transport or passive transport. what is the difference between active transport and passive transport?

Essentially the answer is in the names. Active transport requires energy to facilitate to movement of the materials while passive transport is something like osmosis which is when the material moves based on concentration in an effort to create equality between the two sides. Basically passive is when the materials move under the own power

Explanation:

i think that d. wind is the answer.   i missed the question when i answered a. currents.

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.
