Yes, extra chromosomes can be received by the tasmanian devil.
Explanation:
Extra chromosomes can be received by the tasmanian devil due to tumor disease in the tasmanian devil. In the beginning the old genome of tasmanian devil has 13 chromosomes but with the tumor disease, it receives one extra chromosome and completed 14 chromosomes.

I would say B
Explanation:
Because atural selection is the mechanism for how evolution occurs over time.

The correct answer is B. Secondary succession
Explanation:
In ecosystems, secondary succession occurs as certain events such as fires cause vegetation to temporarily disappear from one area. However, as soil is not affected negatively, vegetation grows again after some time, which means there is a secondary growth of vegetation and changes in the structure of an ecological community.
This term applies to the situation in the 1988 fires in Yellowstone Park because the fire destroyed the vegetation in the zone temporarily, but as the soil was intact after years or decades the vegetation will grow again, although this might implied changes in the ecosystem.
