Answer:

C. Osmosis

Explanation:

Osmosis is the net movement of solvent molecules, usually water, from a region of lower solute concentration to a region of higher solute concentration through a partially permeable membrane. Osmosis is a very useful for moving materials in and out of the cell.

Solutions are mixtures of solutes and solvents. The main aim of osmosis is for all the mixture part to be uniform and the solvent equally dispersed to all the part of the solution.

Osmosis is controlled to a large extent by concentration gradient.

Diffusion on the otherhand is the movement of molecules of a substance from one position to another.

Facilitated diffusion and active transport are just mechanisms for transport within a cell or a body.

Answer:s

In order to test for balance and positioning(proprioception)   as a measure of  neurological function, or to test level   of intoxication alcohol  during driving, Romberg test is usually conducted,which can be negative or positive.It is generally used to investigate the cause of loss of motor control in individuals.

Explanation:

A positive result  showed that her  ataxia was due to loss of positioning due to loss of  sensory from sensory neurons.However if negative as in the case of Susan, then it  is to due to abnormality/dysfunctions   in the cerebellum, and not due to loss of sensory functions,
