Answer:
Diffusion is the net movement of any substance from a higher concentration region to the lower concentration region. It is conducting by a concentration gradient.
Osmosis is a process in which solvent (molecules) pass through a semipermeable membrane (SPM) from a lower concentration solution region to a higher concentration region so it equalizes the concentrations on each side of the SPM.
A <u>hypotonic solution</u> is a solution that has a higher concentration of solutes inside the cell than outside of the cell. Thus the movement of water is from outside to the inside of the cell.
A <u>hypertonic solution</u> is a solution in which solutes concentration is greater outside the cell and low concentration inside. The movement of water is from inside the cell to outside the cell.
An <u>isotonic solution</u> where two solutions having the same concentration inside and outside of the cell so there is free movement of molecules across a semipermeable membrane.

In excessive earnings nations the bulk of humans die of simply vast organizations of reasons: cardiovascular sickness and cancer. As cardiovascular sicknesses declined, extra humans died from cancer. The proportion of deaths from maximum different vast reasons of dying increased, too. This has brought about more range in reasons of dying. Generally, wealthier international locations have a better common existence expectancy than poorer international locations, which may be argued to be done via better requirements of living, extra powerful fitness systems, and extra assets invested in determinants of fitness (e.g. sanitation, housing, education).
Thus, option a is the correct choice.
