Answer:
The tryptophan synthase enzyme catalyzes the synthesis of tryptophan. This enzyme is found in all kingdoms except animals.
Tryptophan synthase has a hydrophobic channel that facilitates the passage of an intermediate from one enzyme to the other during the biosynthesis of tryptophan, which makes faster the metabolic process.
Abiotic means non-living. So the correct answer is "the lack of oxygen in coastal waters"
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.
