Question: Answer the following question given this paragraph: Digestion of Carbohydrates Carbohydrate digestion begins in the mouth (Figure 20.5 "The Principal Events and Sites of Carbohydrate Digestion"), where salivary -amylase attacks the -glycosidic linkages in starch, the main carbohydrate ingested by humans. Cleavage of the glycosidic linkages produces a mixture of dextrins, maltose, and glucose. (For more information about carbohydrates, see Chapter 16 "Carbohydrates". ) The -amylase mixed into the food remains active as the food passes through the esophagus, but it is rapidly inactivated in the acidic environment of the stomach. Figure 20.5 The Principal Events and Sites of Carbohydrate Digestion. Q: Where does carbohydrate digestion begin in the body? Choices: - stomach - intestines - throat - mouth A:
Answer: mouth

Question: Answer the following question given this paragraph: Reptiles have a circulatory system with a heart that pumps blood. Reptiles also have a centralized nervous system with a brain.

They use their tongue to smell scents. That's what the blue-tongued lizard in Figure below is doing. Some reptiles also have a heat-sensing organ that helps them locate the warm bodies of prey animals such as birds and small mammals.
