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.

Explanation:
A three dimensional universe is comprised of three measurements, width, breadth, and height.
In a three-dimensional universe, the position of a spacecraft is defined by its location. In a four-dimensional system, the spacecraft defines a line that represents events through which the object passes.
