The dispersal of ink in a beaker of water is an example of?
a) diffusion
b) osmosis
c) active transport
d) endocytosis

The best answer is A

Diffusion is said to be the movement of particles, molecules ions from a region where they are more concentrated to a region where they are less concentrated.

Diffusion does not require a semi - permeable membrane and is purely dependent upon the free energy of the diffusing substance only.

Ink particles spread (diffuse) from the drop of ink where they are more concentrated  to all the part of the water in the beaker until they are evenly distributed, thus reaching a state of equilibrium.

i would say the prokaryotic cells the prokaryotic cells are less complex, are usually found only in unicellular organisms and have more limited capabilities than eukaryotic cells.
