Answer:
B - invasive species
Explanation:
Invasive species are species that are not native to a particular habitat but are introduced into that habitat intentionally or by accident.
The Burmese python was released in Florida (where it is not a native species). Because it is not from Florida, it does not have any natural predators there, and it can seriously damage the ecosystems by preying on organisms that have no adaptations against the new predator.
Answer:
Soil getting dug up by moles.
Bacteria cell has chromosomal and plasmid dna and is prokaryotic (without a nucleus). Animal cell is eukaryotic (with a nucleus).
Bacteria cell has cell wall and cell membrane, but animal cell only has cell membrane.
Bacteria cell has no mitochondria, animal cell does.
Bacteria cell has flagella, animal cell doesn’t.
Answer:
Option B, Mammals and reptiles in the post-dinosaur age.
Explanation:
Adaptive radiation is mechanism through which species evolve very fast from common single ancestors. In simple words two different species are said to have evolved through adaptive radiation when they have descended from a single lineage. This is not the case with mammals and reptiles.
Generally in adaptive radiation, a species evolve when it faces new environmental challenges due to change of habitat or area. For example mammals have evolved from dinosaurs.
Hence, option B is correct
