Habitat isolation, in which two different species occupy different habitats (e. g. one lives in the forest canopy, while the other lives among the vines of a rain forest) is an example of a(n):

Speciation

Explanation:

When two species live in different habitats is called ecological isolation or habitat isolation. The two species can interbreed but they are not likely to meet each other. For example one species occupy forest canopy, while the other lives among the vines of a rain forest. This is an example of prezygotic barrier of speciation.  

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called
