Indirect contact transmission occurs when there is no direct human-to-human contact.
Explanation:

Answer:
B) It breaks down polysaccharides such as starch.
Explanation:
Polysaccharides are long chains of monosaccharides like glucose joined together with glycosidic linkages. While plants can simply make glucose via photosynthesis, animals rely on glucose sourced from their diet. In animals, glucose is stored as glycogen; however, plant storage polysaccharides like starch are regularly broken down through digestion using enzymes.
Enzymes are proteins which catalyze chemical reactions like the breakdown of large polysaccharides. Alpha amylase, an enzyme produced in the pancreas, is also found in human saliva; it catalyzes the hydrolysis, or breakdown of starch into glucose. Amylase acts on polysaccharides bonds at random points along the chain by splitting the α 1-4 glycosidic bonds. This produces maltose, dextrin and glucose; this glucose is used in ATP synthesis via <em>respiration, ethyl alcohol fermentation and lactic fermentation</em>.
