What are the characteristics of supernovae?

2 answers:

5 0

Ans: As the star runs out of nuclear fuel, some of its mass flows into its core. Eventually, the core is so heavy that it cannot withstand its own gravitational force. The core collapses, which results in the giant explosion of a supernova. The sun is a single star, but it does not have enough mass to become a supernova.

The species diversity of an evolutionary lineage will increase when more new member species originate than are lost to extinctio

lesantik [10]

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.
