Answer the following question given this paragraph: When most of the chyme has been absorbed, the small intestinal wall becomes less distended. At this point, the localized segmentation process is replaced by transport movements. The duodenal mucosa secretes the hormone motilin, which initiates peristalsis in the form of a migrating motility complex. These complexes, which begin in the duodenum, force chyme through a short section of the small intestine and then stop. The next contraction begins a little bit farther down than the first, forces chyme a bit farther through the small intestine, then stops. These complexes move slowly down the small intestine, forcing chyme on the way, taking around 90 to 120 minutes to finally reach the end of the ileum. At this point, the process is repeated, starting in the duodenum. Q: What is the natural movement called within your intestines? Choices: - proteolysis - progress - fibroblasts - peristalsis A:
peristalsis

Ques: Answer the following question given this paragraph: Bronchitis is an inflammation of the bronchi, the air passages that conduct air into the lungs. The bronchi become red and swollen with infection. Acute bronchitis is usually caused by viruses or bacteria, and may last several days or weeks. It is characterized by a cough that produces phlegm, or mucus. Symptoms include shortness of breath and wheezing. Acute bronchitis is usually treated with antibiotics. Q: What is the usual treatment for acute bronchitis? Choices: - surgery - physical therapy - pesticides - antibiotics A:
Ans: antibiotics

Answer the following question given this paragraph: Energy is the ability to cause changes in matter. For example, your body uses chemical energy when you lift your arm or take a step. In both cases, energy is used to move matteryou. Any matter that is moving has energy just because it's moving. The energy of moving matter is called kinetic energy. Scientists think that the particles of all matter are in constant motion. In other words, the particles of matter have kinetic energy. The theory that all matter consists of constantly moving particles is called the kinetic theory of matter . You can learn more about the theory at this URL: http://www. youtube. com/watch?v=Agk7_D4-deY . Q: What is the ability to cause changes in matter? Choices: - force - hydrogen - pressure - energy A:
(A).
energy
Ques:Answer the following question given this paragraph: The exact cause of supervolcano eruptions is still debated. However, scientists think that a very large magma chamber erupts entirely in one catastrophic explosion. This creates a caldera into which the surface collapses ( Figure below ). The composition of the eruption is felsic or highly felsic. Q: What kind of eruption do scientists think is caused by a very large magma chamber erupting entirely in one catastrophic explosion? Choices: - brucei eruption - mangxamba eruption - supermagma eruption - supervolcano eruption A:

Ans:supervolcano eruption
Ques: Answer the following question given this paragraph: If evolution can take a very long time, how can we visualize how it happens? Charles Darwin came up with the idea of an evolutionary tree to represent the relationships between different species and their common ancestors ( Figure below ). The base of the tree represents the ancient ancestors of all life. The separation into large branches shows where these original species evolved into new species. Q: Who created the idea of an evolutionary tree to represent the relationships between different species and their common ancestors? Choices: - Carl Sagan - Scopes - Isaac Newton - charles darwin A:
Ans:
charles darwin
