Q: Answer the following question given this paragraph: The Esophageal Phase The entry of food into the esophagus marks the beginning of the esophageal phase of deglutition and the initiation of peristalsis. As in the previous phase, the complex neuromuscular actions are controlled by the medulla oblongata. Peristalsis propels the bolus through the esophagus and toward the stomach. The circular muscle layer of the muscularis contracts, pinching the esophageal wall and forcing the bolus forward. At the same time, the longitudinal muscle layer of the muscularis also contracts, shortening this area and pushing out its walls to receive the bolus. In this way, a series of contractions keeps moving food toward the stomach. When the bolus nears the stomach, distention of the esophagus initiates a short reflex relaxation of the lower esophageal sphincter that allows the bolus to pass into the stomach. During the esophageal phase, esophageal glands secrete mucus that lubricates the bolus and minimizes friction. Q: The entry of food into the esophagus marks the beginning of the esophageal phase of deglutition and the initiation of this? A:

OPTIONS:
- relaxation
- digestion
- propagation
- peristalsis

A: peristalsis

input: OPTIONS:
- knowledge
- reproduction
- shelter
- food Now, answer this question: Answer the following question given this paragraph: Consumers are organisms that depend on other organisms for food. They take in organic molecules by essentially "eating" other living things. They include all animals and fungi. (Fungi don't really "eat"; they absorb nutrients from other organisms. ) They also include many bacteria and even a few plants, such as the pitcher plant in Figure below . Consumers are also called heterotrophs. Heterotrophs are classified by what they eat:. Q: Consumers are organisms that depend on other organisms for what? A:
A:
output: food

Answer the following question given this paragraph: The first and longest phase of mitosis is prophase . During prophase, chromatin condenses into chromosomes, and the nuclear envelope, or membrane, breaks down. In animal cells, the centrioles near the nucleus begin to separate and move to opposite poles (sides) of the cell. As the centrioles move, a spindle starts to form between them. The spindle, shown in Figure below , consists of fibers made of microtubules. Q: What is the first phase of mitosis? A:

OPTIONS:
- metaphase
- telophase
- meiosis
- prophase

Answer: prophase

Problem: OPTIONS:
- 42 percent
- 10 percent
- 25 percent
- 33 percent
Q: Answer the following question given this paragraph: Soil erosion is a natural occurrence. However, human activities have greatly accelerated soil erosion. In some locations, soil may now be eroding about 10 times faster than its natural rate. Since Europeans settled in the United States, approximately one-third of the topsoil has eroded away. Q: Since europeans settled in the united states, about what percentage of topsoil has eroded away? A:
Answer: 33 percent

Answer the following question given this paragraph: Saturated hydrocarbons are hydrocarbons that contain only single bonds between carbon atoms. They are the simplest class of hydrocarbons. They are called saturated because each carbon atom is bonded to as many hydrogen atoms as possible. In other words, the carbon atoms are saturated with hydrogen. You can see an example of a saturated hydrocarbon in the Figure below . In this compound, named ethane, each carbon atom is bonded to three hydrogen atoms. In the structural formula, each dash (-) represents a single covalent bond, in which two atoms share one pair of valence electrons. Q: What are hydrocarbons that contain only single bonds between carbon atoms called? A:

OPTIONS:
- caloric hydrocarbons
- unsaturated hydrocarbons
- carcinogenic hydrocarbons
- saturated hydrocarbons

Answer:
saturated hydrocarbons
