Answer:
3) away from the area where it is more concentrated
Explanation:
A substance that moves across a cell membrane without using the cell's energy tends to move away from the area where it is more concentrated.
It is known as passive transport.
It is the process in which substance without using the cellular energy tend to move down the concentration gradient.
It is also known as simple diffusion.
All other options are incorrect because,
In case of active transport substance move against the concentration gradient i.e to wards the area of higher concentration.
This process require energy.
Cilia helps in movement of the organism, it can pass the content (gases like CO2, O2) so they can transport. It can migrate an organism to more sustainable environment
