During normal climatic conditions with regular rainfall, the average beak depth for a population of finches was 6.8mm. researchers found that after a drought, average beak depth increased to 8.8mm. birds with deep beaks (> 9mm) were better able to eat large, hard seeds. small hard seeds were also available after the drought, but could only be eaten by birds with shallow beaks (< 7mm). choose the graphical representation and term that best represents what would happen in the post-drought finch population if both types of seeds continue to be available.

The given case is an example of disruptive selection.

The disruptive selection, also known as diversifying selection, illustrates modifications in population genetics in which extreme values for a trait are preferred over transitional values. In this situation, the variance of the trait upsurges and the population is differentiated into two different groups.

the alkaline earth metals (beryllium (be), magnesium (mg), calcium (ca), strontium (sr), barium (ba), and radium (ra)) are a group of chemical elements in the s-block of the periodic table with very similar properties: shiny. silvery-white. hopefully this ? i didn't fully understand the question
