Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is true of diffusion?Choose 1 answer:
A
Diffusion of particles along the concentration gradient will occur until particles are equally distributed in all areas of the solution.
B
Diffusion of particles against the concentration gradient will occur until all the particles have dissolved
C
Diffusion of particles along the concentration gradient will occur until the particles move fully from one side of the solution to the other.
D
Diffusion of particles against the concentration gradient will occur until random motion occurs.
Explanation: 

Detailed explanation-1: -Diffusion of particles along the concentration gradient will occur until the particles move fully from one side of the solution to the other.

Detailed explanation-2: -Answer and Explanation: The correct answer is b. Molecules will move from high to low concentration until equilibrium is reached. This is a passive process, so it does not require energy.

Detailed explanation-3: -Which of the following must be true for diffusion to occur? There must be areas of different concentrations.

Detailed explanation-4: -Diffusion: The movement of molecules in the direction of concentration gradient Le from a region of higher concentration to that of lower concentration is called diffusion.

Detailed explanation-5: -Diffusion of particles along the concentration gradient will occur until particles are equally distributed in all areas of the solution. Diffusion of particles against the concentration gradient will occur until random motion occurs.
