The experiment to test whether cigarette smoke affects the functioning of the various parts of the digestive system . Introduction: The smoke of cigarette is a complex mixture of chemical compounds bound to aerosol particles or present free in the gaseous phase. The particulate phase poses the risk for cancer, cardiovascular disease, and heart disease. Acrolein and acetaldehyde are respiratory irritants; and cyanide, arsenic, and the cresols were the primary sources of cardiovascular risk. Other chemical classes of concern include other metals, N-nitrosamines, and polycyclic aromatic hydrocarbons (PAHs). The particulate phase includes carboxylic acids, phenols, water, humectants, nicotine, terpenoids, paraffin waxes, tobacco-specific nitrosamines (TSNAs), PAHs, and catechols.

Can you help me with these questions? (A)Rank the test tubes in order of greatest amount of digestion to least amount of digestion. For each tube, explain why it would have exhibited that level of digestion. (B)How could the experiment be modified to further test human digestion actions? What variables would you change? What would you keep the same? (C)In which test tube was the activity most like that of a real human stomach? Explain. Here is the picture.
