Sunlight, because it provides a source of energy.
What’s the picture for the question that you need an answer for?
Answer:
C.
Explanation:
The glutamine Synthetase of E. coli can collectively and totally be hindered and inhibited by various and numerous nitrogen-containing compounds like histidine, tryptophan, glycine, alanine, etc at optimum concentrations. But, individually at higher concentrations, these inhibitors can only inhibit the catalytic enzyme action partially. In this way, GS is constrained by total feedback restraint. Consequently, histidine will repress GS halfway. The excess GS movement can uphold NH+, absorption, and E. coli growth development.
The birds have different mating seasons would answer the question whether the two bird species are actually the same species or just two different ones. The reason for this is that when two bird species have different mating seasons this actually tells us that they most likely don't mate with each other and for that reason it wouldn't be really possible for them to be one species.
