Use the following information to answer the question(s) below.
two populations of birds with somewhat different coloration live on opposite sides of a peninsula. the habitat between the populations is not suitable for these birds. when birds from the two populations are brought together, they produce young whose appearance is intermediate between the two parents. these offspring will breed with each other or with birds from either parent population, and all offspring of these pairings appear intermediate to various degrees.
what keeps the two populations separate?

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

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.
