Of fresh green paper strips were placod in sucrose solutions of varying concentrations to investigato the
changes in mass. The striper, each measuring (4 x 0.5 cm were to cut from the walls the truit at
total of 18 strips were out and the mass of each dortorminod Three stripes were then placed
in the following solutions: 0. 20.4, 0.6,0.8 $ to lomol Idms, rospectively theree were placed
in distilled worler. All were lett for 30min and then removed & rewoiched The mean
mous of each group of three strips was calculanted. The results were recorded on a table shown below

Agroup of 50 adult male humans were in a clinical study to determine how much niacin is toxic. during the first two weeks of the study, members of the group consumed only a formula diet that was nutritionally complete, except it contained 24 mg niacin, which is 1.5 times the rda for niacin (males). at that point in the study, all members reported feeling fine. during the next week, they were given a formula that contained 48 mg niacin. within a few days of consuming this formula, 90% of the participants reported feeling ill, and they complained of having upset stomachs and reddened facial skin. at that point, researchers gave the subjects a formula that contain 16 mg niacin. after a week of consuming the new formula, all participants reported feeling well again. based on this information, the researchers concluded that the amdr for niacin is between 16 and 24 mg/day. ul for niacin was between 24 and 48 mg/day. human requirement for niacin is 16 mg/day. eer for niacin was 16 mg/day.
