Answer:
Two European men and two Polynesian women settled on a previously uninhabited tropical island. All four of the settlers have brown eyes, a dominant trait, but one of the Europeans is heterozygous and carries the recessive gene for blue eyes. No new settlers arrive,and nobody leaves the island.After a few generations,the percentage of blue-eyed individuals increases from the original zero to 25 percent.This is probably due to which of the following factors?
genetic drift
Explanation:
Genetic drift entails when there are changes in the gene frequency which occur in a gene that is existing. From the analogy above, it is a known fact that only gneetic drift could allow such to happen as mutation will only occur with a sudden change of gene which is not the case described above
A cell is made up of different structures
I think it’s A... not sure! Because you have no A so maybe A
Solar energy<span> drives the </span>cycle by evaporating water<span> from the oceans, lakes, rivers, and even the soil. Other </span>water<span> moves from </span>plants to<span> the atmosphere through the process of transpiration.</span> Plants put down roots into the soil to draw water and nutrients<span> up into the stems </span>and leaves. Some of this water<span> is returned to the air by transpiration (when combined with evaporation, the total process is known as evapotranspiration).
