A type of algae has been found living in two different habitats. Habitat A has a higher concentration of carbon dioxide than Habitat B. Based on this finding, which statement describes the most likely outcome? Choose the correct answer. A. Habitat A will have reduced amounts of atmospheric carbon dioxide.
B. The algae in Habitat B will have an increased rate of photosynthesis.
C. The algae in Habitat A will have an increased rate of photosynthesis.
D. Habitat B will have higher amounts of dissolved oxygen.

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.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
