Question

Which statements about particle movement in the image to the right are true? Check all that apply

Answer 1

Answer:

The correct answer is it occurs naturally by diffusion.

Explanation:

Diffusion is one of the most important passive transport mechanism which helps in the movement of small molecules and gases across the plasma membrane down their concentration gradient.

   In simple words diffusion deals with the transport of small molecules and gases from the region of high concentration to the low concentration region untill the contration of both the regions become equal.

Answer 2

Answer:

It occurs naturally by diffusion

Explanation:

Diffusion is the movement of molecules from the region of higher concentration to the region of lower concentration without necessarily having a medium.

There are three types of diffusion namely: expansion diffusion, stimulus diffusion, and relocation diffusion.

For the movement to occur, energy is not needed because the particles move along the concentration gradient with sometimes the help of carriers (protein carriers).
