A
Koalas in current populations are no longer able to successfully breed with other species.

(Choice B)
B
The current koala populations are less likely to be able to adapt to environmental changes.

Koalas in current populations are more resistant to new diseases.

(Choice D)
D
The current koala population is less likely to be inbred.

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
