In many people, the production of lactase diminishes through age and they become lactose intolerant.

label test-tubes 1 – 6. Attract a line 1 cm from the bottom of every test tube and another line 2 centimeter from the bottom of each tube. Fill in Table 1 come specify which tube will get which check substance. Include the appropriate test solution to the level that the 1 cm line. Add Benedict"s reagent come the 2 cm line of each tube. Mix gently. Document initial shade in Table 5.1. This is the shade after Benedict’s reagent has been added but before heat. Boil, or warmth tubes in the warm water bath for 5 minutes.
