Answer:
Earth's atmosphere is a layer of gases surrounding the planet Earth and retained by the Earth's gravity.

Answer:
A predominance of pine trees
Explanation:
Usually pine trees become a target of fire and can overcome the soil that has been a exposed to fire. Hence, in a woodland that has been frequented by fire, there is growth of pine trees rather than other trees/plants.
Answer:
I would expect to see a new phenotype in which the new duck hybrid species would express a new mixed courtship dance with the behaviors of both parentals.
Explanation:
The cross between both parentals, each from different species, might produce a new phenotype that exhibits both parental dances. The new dance might be considered a hybrid of the parental dances.
Genetically speaking, we can think that there is a gene codifying for the courtship behavior in one species and another gene expressing a different courtship behavior in the other species. This cross´ product would be a hybrid species that exhibits a part of both parentals´ behaviors.
Despite these similarities, prokaryotes and eukaryotes differ in a number of important ways. A prokaryote is a simple, single-celled organism that lacks a nucleus and membrane-bound organelles.
