Answer: Option B) Common salt
Explanation:
An inorganic compound is one that does not contain carbon at all or contain carbon atoms that are not covalently bound to other atoms.

Answer:
C
Explanation:
a difference in the pH of an environment changes enzymes activity
Their differences may eventually stop the separated squirrels from breeding with one another this is an example of an Allopatric speciation
Explanation:
In allopatric speciation, species from the same population evolve some different characters due to the differences in geographical locations.
In this scenario, the species become reproductively isolated and diverge.
The mating times of the squirrel have changed due to the environmental changes.
They no longer interbreed and hence no viable offspring thus sexually isolated from each other.
