Answer:
Blocking effect
Explanation:
The scenerio described in the question is blocking effect. Blocking effect According to Kamin can be regarded as effect of conditioning of an association that exist between two different stimuli, i.e a conditioned stimulus and unconditioned stimulus which is been impaired if, at the process of conditioning, conditioned stimulus is been presented along with unconditioned stimulus which has been connected along with the unconditioned stimulus. It explained that blocking of conditioning to a stimulus is possible provided that the stimulus is been reinforced in conjunction along with previously conditioned stimulus.

Answer:
C. placing cells in an environment with a lower solute concentration than that in the cells.
Explanation:
In pathological or diagnostic laboratories, to perform the differential leukocytes count (DLC) or white blood cells (WBC) count which are granulocytes, lymphocytes and monocytes we should first lyse the erythorcytes or red blood cells (RBC) with RBC lysis buffer. When RBC's lysis occur then only WBC's remain in the solution. Then, we add the hypotonic solution or lower solute concentration solution. By adding the hypotonic solution the cells will swell and increase in size.
So, the researchers used the hypotonic solution or lower solute concentration solution to increase the size of cells to differentiate between them.
Note:
In hypotonic solution the cells are increased in size or swell.
In hypertonic solution the cells are decrease in size or shrink.
In Isotonic solution the cells size remain same as normal.
