Answer:
A. 2 speciation events and 5 extinctions
B. 5 speciation events and 1 extinction
Explanation:
As we can see from the diagram, there were only 2 ,aim speciation events for lineage A. The extinction events were 5 for the A lineage. Hence, as the extinction event was more rapid than the speciation event so lineage A contains only one species.
On the other hand, the diagram shows that for lineage B there were 5 speciation events and just 1 extinction event. Hence, the number of species in lineage B were more at the time zero as just one extinction had occurred.
Answer:
Both A and B
Explanation:
Burning fossil fuels produces carbon dioxide.
Cellular respiration produces carbon dioxide.
Both produce carbon dioxide.
Both A and B.
Cold air will underlie warmer air at higher altitudes. :^)

Energy is released when a chemical bond forms between two identical atoms
Answer: An extra cytoplasm enhance survival of a developing oocyte in such a way because cytoplasm serves as a reservoir of lipids, polysaccharide and lipids for the developing embryo.The more the cytoplasm content, more will be the nutrients for the developing embryo. The cytoplasm forms the yolk and provides nourishment to the developing embryo. As we know that the developing embryo requires more nutrition and the main source of nutrition is cytoplasm because the sperm has no reservoir of its own to provide nutrition to embryo.
Thus, an extra cytoplasm enhance the rate of survival of a developing oocyte.
