Answer: hypotonic, isotonic, hypertonic
Explanation: The tonicity of a solution depends in part on its concentration of the solute that can not pass the membrane (non penetrating solute) relative to that inside the cell.
Hypotonic solution (hypo means less): contains less concentration of non penetrating solute relative to that inside the cell. Water will enter the cell and the cell will swell and late. 
Isotonic solution (Iso means same): it contains thesame solute relative to that in the cell, there will be no net movement of water across the plasma membrane.
Hypertonic solution (hyper means more) Hypertonic solution contain more solute relative to that in the cell. Hence the cell will lose water to its environment and may shrink and die.
 
        
             
        
        
        
Answer:
different assessments of environmental factors
Explanation:
In humans, for predicting the future phenotype of any individual, the PSR is used. 
A trait may be defined as the state of a character that is a distinct variation of the phenotypic characteristic of any organism.
The following factors contributes to the differences in the complex trait risk predictions in the different laboratories :
-- differing methods of the combining risk from the multiple genetic variants.
-- genotyping of the different variants.
-- selection of the different genetic variants for such risk determination.
Thus the factor which does not contribute is :
"different assessments of the environmental factors."
