Answer: A. Geological processes continue over millions of years.
A swamp is a wetland which exhibit the growth of vegetation. It consist of vegetation which is being dominated by trees. When these trees die, the wooden parts sank below the water. The wood remains being deposited at the bottom of the water body causes the formation of coal. Coal formation results due to the wood being compressed and buried. It takes millions of years for the transformation of wood into coal in the geosphere of the swamp region.
Hence, formation of coal is a geological process and it takes millions of years for it's formation.
Changes in local environments can have global effects for several reasons. Animals, like birds, migrate from region to region. A change in one of their environments can cause behavioral changes which will affect other organisms living in these environments. Air and water move among regions.
To find the average number of cell cultured per area, you have to divide the total cell count with the total area. The cultured cells contains 7 x 10^5 cells count in 50 ml of medium area. The number would be: 7 x 10^5 cells / 50ml= 0.14x 10^5 cells /ml= 1.4 x 10^4 cells/ml
