Question

Fill in the blanks by choosing the correct alternative from those given in the brackets.

d. The process by which molecules distribute themselves within the space they occupy, is _____________. (osmosis/diffusion)

• A. Osmosis
• B. Diffusion

Answer 1

Osmosis:

1. Osmosis is a type of diffusion of solvent molecules across a semipermeable membrane from a region of lower solute concentration toward a region of higher solute concentration.

Diffusion:

1. Diffusion is the means of transport through the free movement of molecules from a region of higher concentration to a region of lower concentration.
2. It helps in the distribution of molecules in a particular space based on the concentration gradient.

Final answer: The process by which molecules distribute themselves within the space they occupy, is diffusion.
