The DNA structures of prokaryotic and eukaryotic cells share similarities and differences. One way in which they are the same is thatboth have sugar-phosphate backbonesmost of the DNA is in the form of plasmidsboth have a singular circular chromosomethe DNA is packaged into several linear pieces

Subduction zones form when an oceanic plate collides with another oceanic plate or continental plate. the continental crust is lighter and less dense than oceanic crust. continental crust's density is approximately 2.7 grams per cubic centimeter. oceanic crust is thinner and the average density is about 3.3 cubic centimeters. when the two crustal plates converge the oceanic plate always bends and subducts beneath a continental plate. once the oceanic crust subjects, the rocks are subjected to changes in heat and pressure. because of this, we would expect to find rocks in the area of a subduction. a) clastic b) igneous c) metamorphic d) sedimentary
