Answer:
The populations become adapted to different environments and eventually become so different that they cannot interbreed to produce fertile offspring.
Speciation is the evolution of one species into two different kinds, and when they become isolated, that is the final step, since they cannot interbreed any longer.
Catastrophism is associated with major changes that occurs once at a time in a species while gradualism is associated with tiny changes that occurs over a period of time that finally contributes a bigger evolutionary change.
<u>Explanation:</u>
The events that are sudden, short-lived, violent occurring worldwide thereby changing the shape of the Earth is Catastrophic. This process is opposite to contrast to gradualism which is also called as uniformitarianism. This process is associated with slow and also incremental changes. Erosion is the best example for this process.
The formation of major mountain chains and great floods are some of the examples of Catastrophism. Both are associated with the changes that occurs in a species by the time taken for the changes determines whether it is Catastrophism or gradualism.

Answer:
option C
Explanation:
with regards to the classification of life on the earth, the phylogenetic tree of life has been redrawn to show the three domains which include the archae, the bacteria and the eukarya. This is also known s the three domain syatem over the five-six domain system. This tree also fundamentally recognizes the difference between the two prokaryotes groups which is the archae and the bacteria. in terms of the phylogeny, the tree depicts that all life on earth share a common ancestor with the eukarya group been derived later in time.
