All Tubes incubated for 20 seconds and are filled with 4mL of H2O2 and TUBE 1: 1mL of catalase TUBE 2: 2mL of catalase TUBE 3: 3mL of H20 (water) TUBE 4: 4mL of sucrase Which tube(S) would demonstrate reactive solutions?​

is this for the e2020 class

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.

it is a. i hope this .
