which describes simple diffusion?

solute molecules move across a cell membrane from areas of higher concentration to areas of lower concentration.

substances move across a cell membrane, a process that requires energy in the form of atp.

substances move across the cell membrane, a process that requires no energy.

water moves across a cell membrane in a manner that is dependent on the concentration of solutes.

The answer is "Solute molecules move across a cell membrane from areas of higher concentration to areas of lower concentration."

Explanation:

Simple diffusion specifically involves the movement of (small, uncharged) solutes across a cell membrane. Since diffusion is part of the passive transport umbrella, it also requires no energy since the solutes move down the concentration gradient - from areas of high concentration to areas of low concentration.

Hope that helps! :)

answer; /// i believe that the correct answer is; ///a combination of the birth and death

interphase   is the cell cycle stage in which the cell acquires nutrients, creates and uses proteins and other molecules and starts the process of cell division by replicating the dna. it is the longest stage in the eukaryote cell cycle.

the following   can go wrong during interphase:   a base pair could be mismatched during the duplication process causing a mutation.   correct answer: c
