Answer the following question given this paragraph: Did you ever see a dog sit on command? Have you ever watched a cat trying to catch a mouse? These are just two examples of the many behaviors of animals. Animal behavior includes all the ways that animals interact with each other and the environment. Examples of common animal behaviors are pictured in Figure below . Q: What behavior includes all the ways that animals interact with each other and the environment? Choices: - adaptation - interdependence - instinct - animal behavior A:
animal behavior
Answer the following question given this paragraph: The two major divisions of seed plants are the gymnosperms (seeds in cones) and angiosperms (seeds in ovaries of flowers). Figure below shows how the seeds of gymnosperms and angiosperms differ. Do you see the main difference between the two seeds? The angiosperm seed is surrounded by an ovary. Q: What is the angiosperm seed surrounded by? Choices: - uterus - cone - egg - ovary A:
ovary
Q: Answer the following question given this paragraph: Most human traits have more complex modes of inheritance than simple Mendelian inheritance. For example, the traits may be controlled by multiple alleles or multiple genes. Q: What type of simple inheritance is too simplified to explain most human traits? Choices: - mitosis - spontaneous mutation - etiology - mendelian A:
A: mendelian
Question: Answer the following question given this paragraph: Cell phone signals are carried through the air as microwaves. You can see how this works in the Figure below . A cell phone encodes the sounds of the caller's voice in microwaves by changing the frequency of the waves. This is called frequency modulation. The encoded microwaves are then sent from the phone through the air to a cell tower. From the cell tower, the waves travel to a switching center. From there they go to another cell tower and from the tower to the receiver of the person being called. The receiver changes the encoded microwaves back to sounds. Q: What is the name of the mechanism in which sounds are encoded in microwaves by changing their frequency? Choices: - molecular modulation - shape modulation - mechanical modulation - frequency modulation A:
Answer: frequency modulation

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
Q: Answer the following question given this paragraph: The organs of the respiratory system include the lungs, pharynx, larynx, trachea, and bronchi. Q: Lungs, pharynx, larynx, trachea, and bronchi are part of which system? Choices: - nervous - digestive - neural - respiratory A:
A: respiratory
