I think the best choice to fill in the blank would be disengagement. It is a theory in aging that perceives aging as an inevitable occurrence which results in decreased social interaction between the people in the society and the person. Hope this helps.
Pieces of genes can be inserted into the genetic material of prokaryotes so that they will make the protein products encoded in the genes or copies of the genes themselves
Answer:
b. The frequency of the lap94 allele at different sites results from an interaction between selection and gene flow.
Explanation:
In the southwest portion of the Sound, salinity is relatively low, and selection against the lap94 allele is strong. Moving toward the northeast and into the open ocean, where salinity is relatively high, selection favors a high frequency of the lap94 allele. However, because mussel larvae disperse long distances, gene flow prevents the lap94 allele from becoming fixed in the open ocean or from declining to zero in the southwestern portion of Long Island Sound.
