In order for a genetic mutation in a species to result in the formation of a new species, what must occur?
a. the original species must become extinct.
b. the new species must be unable to breed with the original species. eliminatec) the new species must be visibly different from the original species.
d. the new species must have a larger population than the original species.

B. the new species must be unable to breed with the original species

Explanation: If two organisms can breed with each other, they are members of the same species. For speciation to occur, the new species must be unable to breed with the original species.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
