Answer: Mercury has been well known as an environmental pollutant for several decades. As early as the 1950's it was established that emissions of mercury to the environment could have serious effects on human health. These early studies demonstrated that fish and other wildlife from various ecosystems commonly attain mercury levels of toxicological concern when directly affected by mercury-containing emissions from human-related activities. Human health concerns arise when fish and wildlife from these ecosystems are consumed by humans.
During the past decade, a new trend has emerged with regard to mercury pollution. Investigations initiated in the late 1980's in the northern-tier states of the U.S., Canada, and Nordic countries found that fish, mainly from nutrient-poor lakes and often in very remote areas, commonly have high levels of mercury. More recent fish sampling surveys in other regions of the U.S. have shown widespread mercury contamination in streams, wet-lands, reservoirs, and lakes. To date, 33 states have issued fish consumption advisories because of mercury contamination.
These continental to global scale occurrences of mercury contamination cannot be linked to individual emissions of mercury, but instead are due to widespread air pollution. When scientists measure mercury levels in air and surface water, however, the observed levels are extraordinarily low.
Explanation:
3. It's because of the heat underneath the crust of the Earth. Because heat rises, the molten rock and such underneath the crust rises to the top and then the movement underneath causes things on top to move.
4. Plates are the different sections that the lithosphere has been cracked into. These plates once all fit together as a giant plate called Pangaea.
5. An earthquake is a sudden, sometimes violent shaking of the ground, as a result of the shifting of tectonic plates, or volcanic eruption.
6. On the magnitude scale, earthquakes range from 2.5 or less (usually never felt but strong enough to be detected by seismograph) to 8.0 or higher. Causes extreme damage; enough to destroy whole cities at once if close enough to the epicenter.
7. Depends on what kind you're looking for. I'd look it up for your specific topic.
8. To apply a forces to something, usually resulting in a stretch.
9. The action of compressing something, to flatten or squeeze by pressure
10. A strain on the layers of something because of pressure, resulting in the shifting of those layers.
11. In areas undergoing extension or stretching. It's when the crust is extended.
12. The hanging wall drops relative to the footwall.
13. This is what happens when the hanging wall <u>rises</u> relative to the footwall. (The opposite of a normal fault)

Answer:
A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O).
Explanation:
This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids.
Water is used in many reactions in the body, both enzymatic and chemical. Water within blood and lymphatic system is responsible for the transport of hormones, antidotes oxygen and nutrients.
Metabolism can be described as entirety of chemical reactions which take place within a cell, the result of which is energy for processes which take place in the body.
