Answer the following question given this paragraph: Neural Responses to Food In reaction to the smell, sight, or thought of food, like that shown in Figure 34.20, the first response is that of salivation. The salivary glands secrete more saliva in response to stimulation by the autonomic nervous system triggered by food in preparation for digestion. Simultaneously, the stomach begins to produce hydrochloric acid to digest the food. Recall that the peristaltic movements of the esophagus and other organs of the digestive tract are under the control of the brain. The brain prepares these muscles for movement as well. When the stomach is full, the part of the brain that detects satiety signals fullness. There are three overlapping phases of gastric controlthe cephalic phase, the gastric phase, and the intestinal phaseeach requires many enzymes and is under neural control as well. Q: What does the stomach produce to help digest food? Choices: - acetic acid - lactic acid - amino acid - hydrochloric acid A:
hydrochloric acid

Answer the following question given this paragraph: An electromagnetic wave is a wave that consists of vibrating electric and magnetic fields. A familiar example will help you understand the fields that make up an electromagnetic wave. Think about a common bar magnet. It exerts magnetic force in an area surrounding it, called the magnetic field. You can see the magnetic field of a bar magnet in Figure below . Because of this force field, a magnet can exert force on objects without touching them. They just have to be in its magnetic field. An electric field is similar to a magnetic field (see Figure below ). An electric field is an area of electrical force surrounding a charged particle. Like a magnetic field, an electric field can exert force on objects over a distance without actually touching them. Q: A wave that consists of vibrating electric and magnetic fields is called what? Choices: - mechanical wave - thermal wave - propagate wave - electromagnetic wave A:
(A).
electromagnetic wave
Ques:Answer the following question given this paragraph: The horizontal motion of a projectile does not influence its free fall. Q: What influence does the horizontal motion of a projectile have on free fall? Choices: - decrease acceleration - vertical - increase acceleration - none A:

Ans:none
Question: Answer the following question given this paragraph: An underwater earthquake creates a tsunami this way: The movement of the crust displaces water. The displacement forms a set of waves. The waves travel at jet speed through the ocean. Since the waves have low amplitudes and long wavelengths, they are unnoticed in deep water. As the waves reach shore they compress. They are also pushed upward by the shore. For these reasons, tsunami can grow to enormous wave heights. Tsunami waves can cause tremendous destruction and loss of life. Fortunately, few undersea earthquakes generate tsunami. Q: What type of amplitudes and wavelengths avoid detection in deep water? Choices: - high and long - high and wide - low and wide - low and long A:
Answer:
low and long
