Shortness of breath or difficulty in breathing is also called dyspnea and can be acute or chronic. It has various causes, but mainly can be caused by a problem in the heart or the lungs. Since your heart and lungs are both involved in the transportation of the oxygen to the tissues and the removal of carbon dioxide, any problems occurring to these systems can affect breathing.
B-type Natriuretic Peptide (BNP) reflect the systolic and diastolic activity of the heart and its blood levels can show any heart failure. A BNP test and can help the nurse decide whether the cause of the dyspnea is a heart failure or some respiratory problem.
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.

<span>Which storm is likely to cause quick destruction along a narrow path?
</span>
<span>A.tornado
B.hurricane
C.thunderstorm
Your answer would be a A.Tornado
</span>
<span>Which clouds are best associated with a thunderstorm?
A.high cumulonimbus
B.towering funnel clouds
C.swirling clouds with a calm center</span>
Thunderstorms occur in association with a type of cloud known as a cumulonimbus. So, <span>A.high cumulonimbus
</span>
<span>Which statement best describes the formation of a hurricane?
A.Air pressure differences over the ocean cause fast, spinning winds.
B.An updraft of warm, moist air builds a cumulonimbus cloud.
C.A downdraft of air meets spinning updrafts.
</span>
Hurricanes begin as tropical storms over the warm moist waters of the Atlantic and Pacific Oceans near the equator. As the moisture evaporates it rises until enormous amounts of heated moist air are twisted high in the atmosphere.
<span>A.Air pressure differences over the ocean cause fast, spinning winds.
</span>
<span>How are hurricanes and thunderstorms similar?
A.Both cover an area as large as 650 km.
B.Both involve the formation of large cumulonimbus clouds.
C.Both form when warm air rises, then cools quickly to form clouds.</span>
Hurrica<span>nes and thunderstorms are both convective storms fueled by warm, moist air. </span><span>C.Both form when warm air rises, then cools quickly to form clouds.
</span><span>Is this statement true or false?
Hurricanes are classified by three stages in which updrafts of air
billow up, updrafts and downdrafts swirl the wind up and down, then
downdrafts cause clouds to come apart.
A.True
B.False
This would be true
</span>
<span>Which severe weather condition forms over warm, tropical areas?
A. tornado
B. hurricane
C. thunderstorm
</span>
Thunderstorms result from the rapid upward movement of warm, moist air. They can occur inside warm, moist air masses and at fronts. As the warm, moist air moves upward, it cools, condenses, and forms cumulonimbus clouds that can reach heights of over 12.45 miles.
Hurricanes develop in warm, tropical regions where the
water is at least 80 degrees Fahrenheit The
storms also require moist air and converging equatorial winds.
A tornado can form where winds blow at
different speeds causing rotation which can tighten and speed into a
funnel cloud if caught in the flow of air moving into the storm.
Rain and hail can cause the funnel to bend downward.
<span>B. hurricane is your answer
Hope it helped :)
