Answer to Question 1

Answer: High-energy environments typically occur in fast-moving water, such as a rushing stream or river with high discharge. Common rock types in high-energy environments include breccia and conglomerate, where sediment is lithified. Low-energy environments form in organically rich sediments or areas where water is stagnant or barely moving, such as an ocean basin. Coal and black shale form from the compaction of organic debris and fine-grained muds, respectively.

Answer to Question 2

Answer: Contact metamorphism occurs when a rock is intruded by magma. The heat alters the form of the rock while remaining a solid, causing a metamorphic reaction. Regional metamorphism occurs during mountain building events when large quantities of rock are subjected to intense pressure and high temperatures.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).

Addicts to opiates often avoid treatment because they are afraid of withdrawal. Though unpleasant, with proper management, withdrawal is rarely fatal and passes relatively quickly.

Did you know?

There are major differences in the metabolism of morphine and the illegal drug heroin. Morphine mostly produces its CNS effects through m-receptors, and at k- and d-receptors. Heroin has a slight affinity for opiate receptors. Most of its actions are due to metabolism to active metabolites (6-acetylmorphine, morphine, and morphine-6-glucuronide).

Asthma is the most common chronic childhood disease in the world. Most children who develop asthma have symptoms before they are 5 years old.
