The answer is a) in biogeochemical cycles, nutrients are not synthesized anew but are recycled in the <span>biosphere.

Biogeochemical cycles are pathways by which chemical substances move through biosphere and geosphere (lithosphere), as well as atmosphere and hydrosphere. In these cycles nutrients are recycled, they are not lost. Let's take for example a carbon cycle:
</span>

<span>:- Carbon is released into the atmosphere as carbon dioxide from respiration.</span>

<span>- Producers (plants) absorb carbon dioxide and make carbohydrates in photosynthesis.</span>

<span>- Consumers (animals) eat producers and intake carbohydrates.</span>

<span>- After the death of both producers and consumers, decomposers (such as Actinobacteria, or other bacteria or fungi) eat that dead organisms and carbon are released into the environment.</span>

<span>
</span>

<span>So, carbon is not synthesized anew, but it is recycled.</span>

<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 :)

Dioxin, produced as a by-product of various industrial chemical processes, is suspected of contributing to the development of ca
Degger [83]

Answer: Transcription factors

Explanation:  

The dioxin enters the blood stream and the fat cells and liver cells store it.

While moving inside the cell the dioxin binds to the protein called Aryl hydrocarbon which then binds to the second receptor.  

The complex is then carried to the nucleus of the cell. This tends to on and off certain genes.

This turning on and off of the genes in the cell can lead to serious diseases like cancer, decreased immune function, et cetera.
