a. One normal allele produces as much melanin as two normal alleles.
b. Each defective allele produces a little bit of melanin.
c. Two normal alleles are needed for normal melanin production.
d. The two alleles are codominant.
e. The amount of sunlight will not affect skin color of heterozygotes.

it marks things for degradation via the proteasome. it alters there celluar location.

the potatoes have high sugar concentrations and although these potatoes were different we could seethe effects that their sugar concentrations had in different environments. for example, the potatoes in sample a, were placed in pure water. this created a hypertonic environment and caused the potatoes to draw in water from its surroundings. we saw the opposite happen with the potatoes in sample b when placed in the sodium chloride solution. the potatoes in this case were in a hypotonic solution and therefore lost water to their surroundings.
