Snowshoe hares are related to rabbits and live in cold regions. In warm weather, they have a brown coat and spend many hours feeding on vegetation. To avoid predators they either remain still and try to blend into their habitat, or use their powerful hind legs to flee. What change brought about by the winter season would help these animals avoid predators in the snowy climate?

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.
