Other hypotheses for the tree of life present the Archaea as the ancestors to all other organisms. Make a sketch of a phylogenetic tree that presents Bacteria and Eukarya as more closely related to each other than to Archaea, and has Archaea as a sister group to Bacteria and Eukarya. Drag the appropriate labels to their respective targets. Place more closely related groups in alphabetical order from the top to the bottom.

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.
