Earth's mantle plays an important role in the evolution of the crust and provides the thermal and mechanical driving forces for plate tectonics. Heat liberated by the core is transferred into the mantle where most of it (> 90%) is convected through the mantle to the base of the lithosphere.
        
                    
             
        
        
        
Answer:
Guillain-Barre syndrome.
Explanation:
Guillain-Barre syndrome may be defined as the a rare disorder in which the nerves of an individual are attacked by the body's immune system. The symptoms include tingling, weakness and paralysis.
The spinal nerves gets progressively reduced causes the muscle weakness. The individual get attacked by the paralysis in a 24 to 72 hours of the period. The peripheral nervous system of the body gets damaged in this disease.
Thus, the answer is Guillain-Barre syndrome.
 
        
             
        
        
        
Well, considering if the deer and the hawk have a direct predator prey relationship, where the deer are the prey, then the hawk population will also drop quite a lot, unless they have some other major food sources, but chances are they'll still drop.
If it's NOT a direct predator prey situation, for example: The deer happen to eat something that the hawks also eat, or the deer are prey for something the hawks eat:
If the deer eat something the hawks eat, by them dropping it means there will be more food supply for the hawks, meaning as the deer population drops, the hawk population will go up.
If the deer are PREY to something the hawk eats, then by there being less deer, then whatever the primary consumer of the deer is will also drop. If the hawk eats that predator, then there will be less of those predators, and less prey, meaning the hawk population will still drop
You were most likely given a food web to look at. Seeing how you didn't post that, I just gave you the only 3 situations that could happen.

The correct statement describing environmental consequence of unsealed Landfills is : ( A ) Landfills can produce carbon dioxide that leak into the atmosphere 
A landfill is composed of 4 essential components and some are ; 
- bottom linear
- hydrogeologic component and 
- A cover ( seal ) 
Given that a landfill constitutes of about 40 to 60 percent of C0₂ the environmental consequence of not providing a proper seal for the landfill will be the leakage of C0₂  into the atmosphere. while
The release of Heavy metals as leach ate into the surrounding can be controlled with the provision of a system in the landfill, materials in landfill undergo decomposition for a long period of time.
Hence we can conclude that  Landfills can produce carbon dioxide that leak into the atmosphere.
