Thousands of years ago in a land far away, plate tectonics created a mountain range that separates a population of red parrots. on the east side of the mountain, the recessive trait of blue feathers was selected for because it the parrots avoid predators. however; on the west side of the mountain the parrots kept the trait of red feathers. one day, to escape a storm, a small number of blue parrots migrated to the west side of the mountain where the red parrots dwell. identify and explain the evolutionary mechanism at work in this scenario, then predict how the populations of parrots will be affected by the migration.

the wetland preservation movement began in the u.s. in earnest with the clean water act (cwa) of 1972. although not specifically written to protect wetlands, the cwa is comprised of a series of regulations designed to prevent pollutants from contaminating u.s. waters.

answer: the correct option is d. enzyme

lactase and carbonic anhydrase are the examples of enzymes.

lactase is an enzyme, which is present in the small intestine of mammals. it in the digestion of the disaccharide, lactose ( milk sugar) by converting it into two monosachharide, which are glucose and galactose.

carbonic anhydrase is present in the red blood cells. this enzyme plays significant role in the transport of co₂. it in the conversion of co₂ and h₂o into carbonic acid, which is then dissociated into bicarbonate ions and hydrogen ions.
