D. It allows a variety of substances to dissolve in and around cells.
Explanation:
The shell of hydration is important to life because it allows a broad range of substances to dissolve in and around the cells. 
- The shell of hydration allow for water to dissolve a wide range of substances and disperse them uniformly in it. 
- Water serves a solvent capable of dissolving a wide range of substances because it forms a hydration shell round them. 
- This allow for materials to be in solution around the cell. 
- Diffusion and osmosis can readily now take place.

Answer:
Incomplete dominance
Explanation:
Incomplete dominance is the expression of phenotype of two paired alleles (i.e dominant and recessive allele) all together. 
Usually when two alleles get paired, the characteristics of the dominant allele is expressed while the characteristics associated with recessive alleles are expressed only when the two recessive allele get paired. 
Here in this case the characteristics of both type of allele are expressed i.e. both orange and purple strips appear in the offspring. Hence, this case shows the incomplete dominance.
