Question

the concentration of solutes is the same both inside and outside of the cell the concentration of solutes is less outside the cell than inside the cell the concentration of solutes is greater outside the cell than inside it the diffusion of water across a selectively permeable membrane the movement of molecules from a region of high concentration to a region of low concentration by means of random molecular motion a membrane that allows only specific molecules to move into or out of the cell A. diffusion B. isotonic C. hypotonic D. hypertonic E. osmosis F. selectively permeable

Answer 1

Answer: The concentration of solutes is the same both inside and outside of the cell : isotonic

The concentration of solutes is less outside the cell than inside the cell : hypotonic

the concentration of solutes is greater outside the cell than inside it: hypertonic

the diffusion of water across a selectively permeable membrane: osmosis

the movement of molecules from a region of high concentration to a region of low concentration by means of random molecular motion :   diffusion

a membrane that allows only specific molecules to move into or out of the cell : selectively permeable

Explanation:

The solutions having same osmotic pressure and hence same molar concentration are termed as isotonic.

If a solution is of lower osmotic pressure it is called as hypotonic with respect to the concentrate solution.

The more concentrated solution is said to be hypertonic with respect to the dilute solution.

Osmosis is defined as the process in which molecules of a solvent tend to move through a semipermeable membrane from a region of low concentration solution to a region of more concentrated solution.

Diffusion can be defined as a phenomenon that occurs in liquid or gases which is the process of movement of solute particles from area of high concentration to low concentration.

Selectively permeable membrane is a membrane which allows selective movement of molecules.
