The correct answer is - e. longer life expectancy.
The chronic diseases most commonly affect the older population, due to the weakening of the body as it gets into the latter stages of its existence. Since the life expectancy has increased significantly in the last century, and it is further increasing, even though with lower tempo nowadays, there's more and more people that reach older life, thus the number and percentage of the chronic diseases is ever-growing, especially in the developed countries where the population is in general aging as well.
Answer: The release of methane from thawed permafrost
Explanation:
With increasing global warming, permafrost in the arctic is melting. The carbon and methyl clathrates present in permafrost escape into the atmosphere to form carbon dioxide and methane, both greenhouse gases.
In the Arctic, molecules of methane are trapped in ice crystals as methyl clathrates. When the temperature increases, these crystals release methyl clathrates which become methane when in contact with the atmosphere.
The cause of the increasing atmospheric 
is due to the the thawing of dead organisms present in the permafrost. As the permafrost melts, these organisms decay and release into the atmosphere.
New crust typically forms from separating plates, so it would be A: divergent boundary.
Answer:
-5x² +6x
Explanation:
The given expression is :
-3x(x-4)-2x(x+3)
It can be done as follows :
-3x(x-4)-2x(x+3) = (-3x)(x)-(-3x)(4) - 2x(x)-2x(3)
= -3x² +12x -2x² -6x
= -3x²-2x² +12x-6x
= -5x² +6x
Hence, the equivalent expression is equal to -5x² +6x.
