Amino acids are the monomers of proteins. each amino acid consists of a carbon atom bound to a hydrogen atom, an amino group (-nh2), a carboxyl group (-cooh), and a variable r group. which functional group acts as an acid?

The -COOH group of the protein molecule act as acid .

Explanation:

According to Arrhenius law the substance that can donate proton in an aqueous solution is known as acid.

    From this point of view it can the stated that the carboxylic group -COOH act as acid because -COOH group donates proton in aqueous solution and exist as COO-.Thus -COOH group of a protein molecule act as an acid.

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 : )
