Organisms don’t all reproduce the same way. however, by comparing the cells embryos mode of reproduction of these organisms, many similarities between them are revealed. these similarities suggest that they’re evolutionarily physically poorly linked. this type of study is called developmental biology.

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.

answer: the answer is b
