abhisar · Answer

Well that's correct.

abhisar · Answer

$\bf Osmosis$ is a special kind of diffusion in which water as a solvent moves from its higher concentration area to lower concentration area across a semi-permeable membrane.

abhisar · Answer

$\bf Active-Transport$ is on other hand is a process in which substances are transported from lower concentration region to higher concentration region by using energy.

abhisar · Answer

$\bf Facilitated-Transport$ is a kind of transport system which is guided by $\bf Channel-Proteins$. This system does not require energy and transports the material from higher to lower concentration.

abhisar · Answer

The only option left is $\bf Diffusion$. It is the process in which gases spread from their higher concentration to lower concentration.
