There are choices for this question namely:

a. cementation of clastic sediments and precipitates from seawater
b. compaction and recrystallization of volcanic material 
c. regional metamorphism of sedimentary and igneous rocks 
d. contact metamorphism of unconsolidated gravel

The correct answer is that the bedrock of the Adirondock mountains is formed mainly by regional metamorphism of sedimentary and igneous rocks. The geology of the Adirondock mountains formed around 5 million years ago with rocks over 1000 million years old. At this very ancient age, the sedimentary and igneous rocks in the Adirondock mountains have undergone extensive heat and pressure hence regional metamorphism of the existing sedimentary and igneous rocks.

Why is bacteria placed in the kingdom prokaryotes

sukhopar [10]

Prokaryotes are chiefly defined as cells without a nucleus to contain the genetic information. Bacteria do not have a nucleus but, like prokaryotes, a nucleoid region in the center where the DNA can be found. Bacteria also do not have membrane-bound organelles, but they do have ribosomes to synthesize proteins. Bacteria vary a lot in the different structures they can have, but these basic factors make bacteria prokaryotes.
