The interactions between biomolecules are often stabilized by weak interactions such as hydrogen bonds. how might this be an advantage to the organism?

The answer is;  They stabilize protein structures and, in addition, the weak interactions allow for reversibility.

They allow protein to be easily folded and unfolded without expending too much energy. An example is their significance in maintaining the alpha helices and beta sheets of proteins, and allowing for DNA to be easily unzipped for biochemical processes such as replication or duplication.  

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 : )
