a negative control is a simple that you will give you a negative result. you are testing for the presence of proteins simple sugars starch and lipids in various foods what would be the best negative control 1. artificial cytoplasm , because it is good buffer 2. a solution contains protein , sugar, starch, but no lipids 3. candy because it has no nutritional value 4. distilled water because it does not contain any of the molecules you are tasting for

i'm gonna put a couple so you can chose from

explanation:

if you know the fur color of the offspring mice, you can use the ratios to identify the genotypes of the parents.

if either parent mouse passes a dominant allele, the offspring will have black fur.

if the parental mice has two different fur color (i.e white and black) , the color of the offspring's fur would be either black, white, or the combination of both (grey)

hope this : )

a few examples of ethical concerns involving genetically engineering of humans include

-privacy of genetically tested people

- potential side effects

-long term effects
