A population of animals is split in half by a river. Before speciation is completed, the two halves are rejoined when a drought causes the river to run
dry. How would this impact the two populations?
O A. The two halves would be reproductively isolated.
B. Traits that had developed through mutation would still exist only in
one of the halves.
C. Speciation would still occur, because the two halves would be too
different genetically to interbreed.
D. The likelihood of speciation would decrease as genes were shared
between the two groups.

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
