Which process is characterized by the movement of particles from an area of high concentration to an area of low concentration across the plasma membrane without the use of energy? a hypertonic transport b active transport c passive transport d dynamic equilibrium

Restless tectonic plates move (shift) between one and fifteen centimeters per year month day minute

Facilitated diffusion move large molecules and/or polar molecules across the cell membrane. what does facilitated diffusion use to do this?

Molecules like glucose and amino acids are not lipid soluble, so cannot cross the cell membrane by simple diffusion. instead, they are shuttled across by carrier proteins in the membrane from high to low concentration. does this process require energy from the cell? this is an example of what type of molecular movement?
