Answer the following question given this paragraph: New species arise in the process of speciation. Allopatric speciation occurs when some members of a species become geographically separated. They then evolve genetic differences. If the differences prevent them from interbreeding with the original species, a new species has evolved. Sympatric speciation occurs without geographic separation. Q: What occurs when some members of a species become geographically separated? Choices: - divergent speciation - symbiotic speciation - reflective speciation - allopatric speciation A:
(A).
allopatric speciation
Ques:Answer the following question given this paragraph: Minerals can form various shapes. Polygons are pictured below ( Figure below ). The shapes form as the minerals are broken along their cleavage planes. Cleavage planes determine how the crystals can be cut to make smooth surfaces. People who cut gemstones follow cleavage planes. Diamonds and emeralds can be cut to make beautiful gemstones. Q: The shapes of minerals form as they are broken along what planes? Choices: - parallel planes - sedimentary planes - calcium planes - cleavage planes A:

Ans:cleavage planes
